373028a166 Code cleanup
Clean up and improve the between-actors collision code:

* Give names to the A, B tuples from BetweenBoxes and call them the stable and
  mover doodads. All ops are from the perspective of the stable (A) box in
  relation to the mover (B).
* Replace the map[*Actor]*Actor collision struct to one that supports arrays of
  colliding actors, enabling one actor to post OnLeave events correctly when it
  overlapped several actors at once.
* Possibly improve on some of the collision bugs along the way.

Some issues remaining:

* If playing AS an offset-hitbox character:
    * Solid hitboxes against closed doors and platforms works OK.
    * Button InHitbox (overlap) checks do not fire (buttons won't press).
* If playing with a non-offset character (e.g. boy.doodad)
    * Solid hitboxes work and Buttons will press correctly.
* Both types of player hitboxes:
    * When touching a static object such as the Start Flag which has an offset
      hitbox of its own: the Start Flag will creep up the level on its Y axis
      when touched before it settles and won't move.

618d4b07c5 WIP: Fix actor collisions with offset hitboxes
When an actor's Hitbox doesn't begin at 0,0 the collision checks between
boxes is buggy. Current progress:

* Player is a 32x64 size sprite with a hitbox of 0,32 32x32 (bottom half)
* Landing onTop works
* Hitting onBottom works
* Bug: colliding from the side currently pushes the player 32px down
  into the floor. With non-offset doodads walking sideways into e.g. a
  locked door halts the X and Y movement until you let go, but offset
  doodads get pushed down mysteriously.

5654145fd8 (Experimental) Run Length Encoding for Levels
Finally add a second option for Chunk MapAccessor implementation besides the
MapAccessor. The RLEAccessor is basically a MapAccessor that will compress
your drawing with Run Length Encoding (RLE) in the on-disk format in the ZIP
file.

This slashes the file sizes of most levels:

* Shapeshifter: 21.8 MB -> 8.1 MB
* Jungle: 10.4 MB -> 4.1 MB
* Zoo: 2.8 MB -> 1.3 MB

Implementation details:

* The RLE binary format for Chunks is a stream of Uvarint pairs storing the
  palette index number and the number of pixels to repeat it (along the Y,X
  axis of the chunk).
    * Null colors are represented by a Uvarint that decodes to 0xFFFF
      or 65535 in decimal.
    * Gameplay logic currently limits maps to 256 colors.
* The default for newly created chunks in-game will be RLE by default.
* Its in-memory representation is still a MapAccessor (a map of absolute
  world coordinates to palette index).
* The game can still open and play legacy MapAccessor maps.
* On save in the editor, the game will upgrade/convert MapAccessor chunks over
  to RLEAccessors, improving on your level's file size with a simple re-save.

Current Bugs

* On every re-save to RLE, one pixel is lost in the bottom-right corner of
  each chunk. Each subsequent re-save loses one more pixel to the left, so what
  starts as a single pixel per chunk slowly evolves into a horizontal line.
* Some pixels smear vertically as well.
* Off-by-negative-one errors when some chunks Iter() their pixels but compute
  a relative coordinate of (-1,0)! Some mismatch between the stored world coords
  of a pixel inside the chunk vs. the chunk's assigned coordinate by the Chunker:
  certain combinations of chunk coord/abs coord.

To Do

* The `doodad touch` command should re-save existing levels to upgrade them.

c4456ac51b Scripting: Bring Self API up to Actor API parity
Updates the Self API to expose more uix.Actor fields:

* Doodad()
* GetBoundingRect()
* HasGravity()
* IsFrozen()
* IsMobile()
* LayerCount()
* ListItems()
* SetGrounded()
* SetWet()
* Velocity() - note: it was Self.GetVelocity() before.

Self.GetVelocity is deprecated and made an alias to Velocity.

5b3121171e Fix touchscreen mode detection
* Touchscreen mode used to be detected based on SDL2 GetNumTouchDevices
  but on a Macbook, the trackpad registers as a touch device - worse,
  GetNumTouchDevices will only start returning 1 the first time some
  devices are touched.
* The result was that on macOS the custom mouse cursor was drawn by
  default, but on the first trackpad touch, would disappear in favor of
  assuming the game is running on a touch screen device (which is not
  the case).
* New method: the render engine has an IsFingerDown boolean which will
  be true as long as at least one finger has registered a FingerDown
  event, but not yet a FingerUp event.
* So as long as one finger is down, the mouse cursor can disappear and
  then it comes back on release. This isn't perfectly ideal for pure
  touch devices (ideally the cursor remains hidden until a mouse
  movement without touch occurs).

a06787411d Resolve circular import errors for Doodle++ plugin
* pkg/plus/dpp is the main plugin bridge, and defines nothing but an interface
  that defines the Doodle++ surface area (referring to internal game types such
  as doodad.Doodad or level.Level), but not their implementations.
  * dpp.Driver (an interface) is the main API that other parts of the game will
    call, for example "dpp.Driver.IsLevelSigned()"
  * plus_dpp.go and plus_foss.go provide the dpp.Driver implementation for their
    build; with plus_dpp.go generally forwarding function calls directly to the
    proprietary dpp package and plus_foss.go generally returning false/errors.
  * The bootstrap package simply assigns the above stub function to dpp.Driver
* pkg/plus/bootstrap is a package directly imported by main (in the doodle and
  doodad programs) and it works around circular dependency issues: this package
  simply assigns dpp.Driver to the DPP or FOSS version.

Miscellaneous fixes:

* File->Open in the editor and PlayScene will use the new Open Level window
  instead of loading the legacy GotoLoadMenu scene.
* Deprecated legacy scenes: d.GotoLoadMenu() and d.GotoPlayMenu().
* The doodle-admin program depends on the private dpp package, so can not be
  compiled in FOSS mode.

6def8f7625 Walk up slopes smoothly, texture freeing improvement
* Fix collision detection to allow actors to walk up slopes smoothly, without
  losing any horizontal velocity.
* Fix scrolling a level canvas so that chunks near the right or bottom edge
  of the viewpoint were getting culled prematurely.
* Centralize JavaScript exception catching logic to attach Go and JS stack
  traces where possible to be more useful for debugging.
* Performance: flush all SDL2 textures from memory between scene transitions
  in the app. Also add a `flush-textures` dev console command to flush the
  textures at any time - they all should regenerate if still needed based on
  underlying go.Images which can be garbage collected.

79996ccd34 ListBoxes Overhaul
* Overhaul the clunky old alpha Edit Level/Doodad menu with a modernized
  version featuring the new ListBox widget.
* The new level loader is a Window that can be spawned from anywhere instead
  of on a dedicated MenuScene.

Updates to doodad scripts:

* Actor.IsOnScreen() checks whether an actor's visual sprite box is on-screen
  in the level viewport. `Self.IsOnScreen()` will check for the current actor.

Other changes

* PlaySound() to deduplicate the same sound effect from playing at once.

cf1bc81f25 Update savegame format, Allow out-of-bounds camera
Updates the savegame.json file format:

* Levels now have a UUID value assigned at first save.
* The savegame.json will now track level completion/score based on UUID,
making it robust to filename changes in either levels or levelpacks.
* The savegame file is auto-migrated on startup - for any levels not
found or have no UUID, no change is made, it's backwards compatible.
* Level Properties window adds an "Advanced" tab to show/re-roll UUID.

New JavaScript API for doodad scripts:

* `Actors.CameraFollowPlayer()` tells the camera to return focus to the
  player character. Useful for "cutscene" doodads that freeze the player,
  call `Self.CameraFollowMe()` and do a thing before unfreezing and sending the
  camera back to the player. (Or it will follow them at their next directional
  input control).
* `Self.MoveBy(Point(x, y int))` to move the current actor a bit.

New option for the `doodad` command-line tool:

* `doodad resave <.level or .doodad>` will load and re-save a drawing, to
  migrate it to the newest file format versions.

Small tweaks:

* On bounded levels, allow the camera to still follow the player if the player
  finds themselves WELL far out of bounds (40 pixels margin). So on bounded
  levels you can create "interior rooms" out-of-bounds to Warp Door into.
* New wallpaper: "Atmosphere" has a black starscape pattern that fades into a
  solid blue atmosphere.
* Camera strictly follows the player the first 20 ticks, not 60 of level start
* If player is frozen, directional inputs do not take the camera focus back.

82884c79ae Signed Levels and Levelpacks
Add the ability for the free version of the game to allow loading levels that
use embedded custom doodads if those levels are signed.

* Uses the same signing keys as the JWT token for license registrations.
* Levels and Levelpacks can both be signed. So individual levels with embedded
  doodads can work in free versions of the game.
* Levelpacks now support embedded doodads properly: the individual levels in
  the pack don't need to embed a custom doodad, but if the doodad exists in
  the levelpack's doodads/ folder it will load from there instead - for full
  versions of the game OR when the levelpack is signed.

Signatures are computed by getting a listing of embedded assets inside the
zipfile (the assets/ folder in levels, and the doodads/ + levels/ folders
in levelpacks). Thus for individual signed levels, the level geometry and
metadata may be changed without breaking the signature but if custom doodads
are changed the signature will break.

The doodle-admin command adds subcommands to `sign-level` and `verify-level`
to manage signatures on levels and levelpacks.

When using the `doodad levelpack create` command, any custom doodads the
levels mention that are found in your profile directory get embedded into
the zipfile by default (with --doodads custom).

ddcad27485 WIP: Chunker size to uint8 and Rectangular Doodads
Convert the Chunker size to a uint8 so chunk sizes are limited to 255px. This
means that inside of a chunk, uint8's can track the relative pixel coordinates
and result in a great memory savings since all of these uint8's are currently
64-bits wide apiece.

WIP on rectangular shaped doodads:
* You can create such a doodad in the editor and draw it normally.
* It doesn't draw the right size when dragged into your level however:
  - In uix.Actor.Size() it gets a rect of the doodad's square Chunker size,
    instead of getting the proper doodad.Size rect.
  - If you give it the doodad.Size rect, it draws the Canvas size correctly
    instead of a square - the full drawing appears and in gameplay its hitbox
    (assuming the same large rectangle size) works correctly in-game.
  - But, the doodad has scrolling issues when it gets to the top or left edge
    of the screen! This old gnarly bug has come back. For some reason square
    canvas doodads draw correctly but rectangular ones have the drawing scroll
    just a bit - how far it scrolls is proportional to how big the doodad is,
    with the Start Flag only scrolling a few pixels before it stops.

a10a09a818 Cheats Menu UI
* Added a Cheats Menu UI accessible from the Settings window's "Experimental"

  the gameplay mode.
* Commonly used cheats all have corresponding buttons to click on, especially
  helpful for touchscreen devices like the Pinephone where keyboard input
  doesn't always work reliably.
* The buttons in the Cheats Menu just automate entry of the cheat commands.
* `boolProp` command has a new `flip` option to toggle their value (e.g.
  `boolProp show-hidden-doodads flip`)

8b5dab6d6f Slippery Pixels + Update Changelog for 0.13.1 2022-10-10 10:52:28 -07:00
ecaa8c6cef SemiSolid Pixels + Icons
* Add new pixel attributes: SemiSolid and Slippery (the latter is WIP)
* SemiSolid pixels are only solid below the player character. You can walk on
  them and up and down SemiSolid slopes, but can freely pass through from the
  sides or jump through from below.
* Update the Palette Editor UI to replace the Attributes buttons: instead of
  text labels they now have smaller icons (w/ tooltips) for the Solid,
  SemiSolid, Fire, Water and Slippery attributes.
* Bugfix in Palette Editor: use cropped (24x24) images for the Tex buttons so
  that the large Bubbles texture stays within its designated space!
* uix.Actor.SetGrounded() to also set the Y velocity to zero when an actor
  becomes grounded. This fixes a minor bug where the player's Y velocity (due
  to gravity) was not updated while they were grounded, which may eventually
  become useful to allow them to jump down thru a SemiSolid floor. Warp Doors
  needed a fix to work around the bug, to set the player's Grounded(false) or
  else they would hover a few pixels above the ground at their destination,
  since Grounded status paused gravity calculations.

701073cecc Doodad/Actor Runtime Options
* Add "Options" support for Doodads: these allow for individual Actor instances
  on your level to customize properties about the doodad. They're like "Tags"
  except the player can customize them on a per-actor basis.
* Doodad Editor: you can specify the Options in the Doodad Properties window.
* Level Editor: when the Actor Tool is selected, on mouse-over of an actor,
  clicking on the gear icon will open a new "Actor Properties" window which
  shows metadata (title, author, ID, position) and an Options tab to configure
  the actor's options.

Updates to the scripting API:

* Self.Options() returns a list of option names defined on the Doodad.
* Self.GetOption(name) returns the value for the named option, or nil if
  neither the actor nor its doodad have the option defined. The return type
  will be correctly a string, boolean or integer type.

Updates to the doodad command-line tool:

* `doodad show` will print the Options on a .doodad file and, when showing a
  .level file with --actors, prints any customized Options with the actors.
* `doodad edit-doodad` adds a --option parameter to define options.

Options added to the game's built-in doodads:

* Warp Doors: "locked (exit only)" will make it so the door can not be opened
  by the player, giving the "locked" message (as if it had no linked door),
  but the player may still exit from the door if sent by another warp door.
* Electric Door & Electric Trapdoor: "opened" can make the door be opened by
  default when the level begins instead of closed. A switch or a button that
  removes power will close the door as normal.
* Colored Doors & Small Key Door: "unlocked" will make the door unlocked at
  level start, not requiring a key to open it.
* Colored Keys & Small Key: "has gravity" will make the key subject to gravity
  and set its Mobile flag so that if it falls onto a button, it will activate.
* Gemstones: they had gravity by default; you can now uncheck "has gravity" to
  remove their Gravity and IsMobile status.
* Gemstone Totems: "has gemstone" will set the totem to its unlocked status by
  default with the gemstone inserted. No power signal will be emitted; it is
  cosmetic only.
* Fire Region: "name" can let you set a name for the fire region similarly to
  names for fire pixels: "Watch out for ${name}!"
* Invisible Warp Door: "locked (exit only)" added as well.
2022-10-09 17:41:24 -07:00
7d15651ff6 "Look At Me" for Doodad Scripts
* New script API method: Self.CameraFollowMe() to draw camera focus toward
  your doodad (it sets the Canvas.FollowActor target.)
* The camera will go back to following the player on any action inputs
  (arrow keys, jump, use, etc.); if the player is constantly on the move
  the camera stays on him even if another actor is trying to take the focus.
* The first few ticks of Play Mode the player character is always followed,
  to allow for Anvils to settle into place without taking the focus.
* Canvas FollowActor: if the actor is 4 times the max scroll speed away,
  allow scrolling in greater leaps of 4 times the max scroll speed.

New and Changed Doodads

* Anvils will take the camera focus while they are falling.
* New doodad: "Look At Me" - a 'camera region' technical doodad. Link it to
  any power source such as a Button - when this doodad receives power it will
  take the camera focus for a few frames. Use it to highlight a door that
  opened far off screen by linking the Button to both an Electric Door and
  a "Look At Me" near the door.
2022-09-24 23:54:51 -07:00
653184b8f8 JavaScript Exception Catcher UI
* Add an exception catcher that pops open a UI window showing errors that
  occur in doodad scripts during gameplay.
* Shows a preview of the header of the error (character wrapped) with a
  Copy button to copy the full raw text to clipboard for inspection.
* Buttons to dismiss the modal once or stop any further errors from
  opening during this gameplay session (until next restart).
* Add developer shell commands to test the exception catcher:
  - 'throw <message>' to throw a custom message.
  - 'throw2' to stress test a "long" message.
  - 'throw3' to throw a realistic message copied from an actual error.
* Scripting engine: console.log() and friends will now insert the script
  VM's name in front of its messages (the filename + actor ID).

94d0da78e7 Swimming Physics and Bubble Pattern
Water pixels finally do something other than turn your character blue!

* When the player character is "wet" (touching water pixels, and so appearing in
  a blue mask), water physics apply: gravity is slower, your jump height is
  halved, but you get infinite jumps to swim higher in the water.
* Holding the jump key under water will incur a short delay between jumps, so
  that you don't just fly straight up to the surface. Tap the jump button to
  move up quicker, you can spam it all you want.

Azulians are also able to handle being under water:

* They'll sink to the bottom and keep walking back and forth normally.
* If you are above them and noticed, they'll jump (swim) up towards you,
  aware of the water and it jumps like you do.
* The Blue Azulian has the poorest vertical aggro range so it isn't a
  very good swimmer. The White Azulian is very good at navigating water
  as it can pursue the player from the furthest distance of them all.

Changes to the editor:

* New brush pattern added: bubbles.png
  * It's the default pattern now for the "water" color of all
    of the built-in palettes instead of ink.png
  * A repeating pattern of bubbles carved out showing the
    level wallpaper.
  * The old "Bubbles (circles.png)" is renamed "Circles"
* The last scroll position is saved with the Level file, so when you reload
  the level later it's scrolled at where you left it.

4efa8d00fc Fancy Mouse Cursors
The gamepad mouse cursor has become THE mouse cursor. It is always visible and your
real cursor is hidden, and this way the game can swap out other cursors for certain
scenarios:

* The Pencil Tool in the editor will use a pencil cursor over the level canvas.
* The Flood Tool has a custom Flood cursor so you don't forget it's selected!

Other improvements:

* The Palette buttons in the editor now render using their swatch's pattern
  instead of only using its color.
* If you have an ultra HD monitor and open a Bounded level in the editor which
  is too small to fill your screen, the editor canvas limits its size to fit
  the level (preferable over showing parts of the level you can't actually play
  as it's out of bounds).
* The "brush size" box is only drawn around the cursor when a relevant tool is
  selected (Pencil, Line, Rect, Ellipse, Eraser)
2022-05-04 22:38:26 -07:00
9b75f1b039 Spit and polish
* New built-in wallpaper: "Dotted paper (dark)" is a dark-themed wallpaper.
* New built-in palette: "Neon Bright" with bright colors for dark levels.
* New cheat: "warp whistle" to automatically win the level.
* In case the user has a VERY LARGE screen resolution bigger than the full
  bounds of a Bounded level, the Play Scene will cap the size and center
  the level canvas onto the window. This is preferable to being able to see
  beyond the level's boundaries and hitting an invisible wall in-game.
* Make the titlescreen Lazy Scroll work on unbounded levels. It can't bounce
  off scroll boundaries but it will reverse course if it reaches the level's
  furthest limits.
* Bugfix: characters' white eyes were transparent in-game. Multiple culprits
  from the `doodad convert` tool defaulting the chroma key to white, to the
  SDL2 textures considering white to be transparent. For the latter, the game
  offsets the color by -1 blue.
2022-05-03 21:15:39 -07:00
75fa0c7e56 Stability and Bugfixes
* Editor: Auto-save on a background goroutine so you don't randomly freeze
  the editor up during.
* Fix actor linking issues when you drag and re-place a linked doodad: the
  level was too eagerly calling PruneLinks() whenever a doodad was 'destroyed'
  (such as the one just picked up) breaking half of the link connection.
* Chunk unloader: do not unload a chunk that has been modified (Set or Delete
  called on), keep them in memory until the next ZIP file save to flush them
  out to disk.
* Link Tool: if you clicked an actor and don't want to connect a link, click
  the first actor again to de-select it.

Updates to the `doodad` tool:

* `doodad edit-level --resize <int>` can re-chunk a level to use a different
  chunk size than the default 128. Large chunk sizes 512+ lead to performance
  problems.
2022-05-02 20:35:53 -07:00
ad67e2b42b New Doodad: Blue Bird
* The blue bird follows the same base AI as the red bird (it has a
  target altitude that it tries to maintain, and it will dive at the
  player) but the blue bird flies in a sine wave pattern around its
  target altitude. It also has a longer scan radius to search for the
  player than the red bird.
* The sine wave pattern of the blue bird means you may fly under its
  radar depending how high it is on average.

Cheat codes that replace the player character are refactored to make
it easier to extend, and new cheats have been added:

* super azulian: play as the Red Azulian.
* hyper azulian: play as the White Azulian.
* bluebird: play as the new Bird (blue).

93623e4e8a Zipfiles as File Format for Levels and Doodads
Especially to further optimize memory for large levels, Levels and
Doodads can now read and write to a ZIP file format on disk with
chunks in external files within the zip.

Existing doodads and levels can still load as normal, and will be
converted into ZIP files on the next save:

* The Chunker.ChunkMap which used to hold ALL chunks in the main json/gz
  file, now becomes the cache of "hot chunks" loaded from ZIP. If there is
  a ZIP file, chunks not accessed recently are flushed from the ChunkMap
  to save on memory.
* During save, the ChunkMap is flushed to ZIP along with any non-loaded
  chunks from a previous zipfile. So legacy levels "just work" when
  saving, and levels loaded FROM Zip will manage their ChunkMap hot
  memory more carefully.

Memory savings observed on "Azulian Tag - Forest.level":

* Before: 1716 MB was loaded from the old level format into RAM along
  with a slow load screen.
* After: only 243 MB memory was used by the game and it loaded with
  a VERY FAST load screen.

Updates to the F3 Debug Overlay:

* "Chunks: 20 in 45 out 20 cached" shows the count of chunks inside the
  viewport (having bitmaps and textures loaded) vs. chunks outside which
  have their textures freed (but data kept), and the number of chunks
  currently hot cached in the ChunkMap.

The `doodad` tool has new commands to "touch" your existing levels
and doodads, to upgrade them to the new format (or you can simply
open and re-save them in-game):

    doodad edit-level --touch ./example.level
    doodad edit-doodad --touch ./example.doodad

The output from that and `doodad show` should say "File format: zipfile"
in the headers section.

To do:

* File attachments should also go in as ZIP files, e.g. wallpapers

c5353df211 LoadUnloadChunk for Memory Optimization
Instead of the loadscreen eager-loading ALL level chunks to Go Images, only
load the chunks within the "LoadingViewport" - which is the on-screen
Viewport plus a margin of chunks off the screen edges.

During gameplay, every few ticks, reevaluate which chunks are inside or
outside the LoadingViewport; for chunks outside, free their SDL2 textures
and free their cached bitmaps to keep overall memory usage down. The
AzulianTag-Forest level now stays under 200 Textures at any given time
and the loadscreen goes faster as it doesn't have to load every chunk's
images up front.

The LoadUnloadChunk feature can be turned on/off with feature flags. If
disabled the old behavior is restored: loadscreen loads all images and
the LoadUnloadChunks function is not run.

Other changes:

* loadscreen: do not free textures in the Hide() function as this runs on
  a different goroutine and may break. The 4 wallpaper textures are OK
  to keep in memory anyway, the loadscreen is reused often!
* Free more leaked textures: on the Inventory frame and when an actor
  calls Self.Destroy()
* Stop leaking goroutines in the PubSub feature of the doodad script
  engine; scripting.Supervisor.Teardown() sends a stop signal to all
  scripts to clean up neatly. Canvas.Destroy() tears down its scripting
  supervisor automatically.

db5760ee83 Optimize memory by freeing up SDL2 textures
* Added to the F3 Debug Overlay is a "Texture:" label that counts the number
  of textures currently loaded by the (SDL2) render engine.
* Added Teardown() functions to Level, Doodad and the Chunker they both use
  to free up SDL2 textures for all their cached graphics.
* The Canvas.Destroy() function now cleans up all textures that the Canvas
  is responsible for: calling the Teardown() of the Level or Doodad, calling
  Destroy() on all level actors, and cleaning up Wallpaper textures.
* The Destroy() method of the game's various Scenes will properly Destroy()
  their canvases to clean up when transitioning to another scene. The
  MainScene, MenuScene, EditorScene and PlayScene.
* Fix the sprites package to actually cache the ui.Image widgets. The game
  has very few sprites so no need to free them just yet.

Some tricky places that were leaking textures have been cleaned up:

* Canvas.InstallActors() destroys the canvases of existing actors before it
  reinitializes the list and installs the replacements.
* The DraggableActor when the user is dragging an actor around their level
  cleans up the blueprint masked drag/drop actor before nulling it out.

Misc changes:

* The player character cheats during Play Mode will immediately swap out the
  player character on the current level.
* Properly call the Close() function instead of Hide() to dismiss popup
  windows. The Close() function itself calls Hide() but also triggers
  WindowClose event handlers. The Doodad Dropper subscribes to its close
  event to free textures for all its doodad canvases.

38a23f00b2 Reset Timer Doodad + Various Fixes
* Bird is not solid when colliding with other birds.
* If the dev shell is used to run JavaScript during Play Mode, consider
  it cheating (so player can't `$ d.Scene.ResetTimer()` for example)
* On Survival Mode levels, DieByFire immediately opens the End Level
  (silver score) modal rather than respawn from checkpoint, so levels
  don't need checkpoint contraptions to end the level.
* During level loading screens, wait and call doodads' main() function
  until the very end.

af6b8625d6 Flood Tool, Survival Mode for Azulian Tag
New features:
* Flood Tool for the editor. It replaces pixels of one color with another,
  contiguously. Has limits on how far from the original pixel it will color,
  to avoid infinite loops in case the user clicked on wide open void. The
  limit when clicking an existing color is 1200px or only a 600px limit if
  clicking into the void.
* Cheat code: 'master key' to play locked Story Mode levels.

Level GameRules feature added:
* A new tab in the Level Properties dialog
* Difficulty has been moved to this tab
* Survival Mode: for silver high score, longest time alive is better than
  fastest time, for Azulian Tag maps. Gold high score is still based on
  fastest time - find the hidden level exit without dying!

Tweaks to the Azulians' jump heights:
* Blue Azulian:  12 -> 14
* Red Azulian:   14 -> 18
* White Azulian: 16 -> 20

Bugs fixed:
* When editing your Palette to rename a color or add a new color, it wasn't
  possible to draw with that color until the editor was completely unloaded
  and reloaded; this is now fixed.
* Minor bugfix in Difficulty.String() for Peaceful (-1) difficulty to avoid
  a negative array index.
* Try and prevent user giving the same name to multiple swatches on their
  palette. Replacing the whole palette can let duplication through still.

647124495b Level Difficulty + UI Polish
Added a new level property: Difficulty

* An enum ranging from -1, 0, 1 (Peaceful, Normal, Hard)
* Default difficulty is Normal; pre-existing levels are Normal by
  default per the zero value.

Doodad scripts can read the difficulty via the new global variable
`Level.Difficulty` and some doodads have been updated:

* Azulians: on Peaceful they ignore all player characters, and on Hard
  they are in "hunt mode": infinite aggro radius and they're aggressive
  to all characters.
* Bird: on Peaceful they will not dive and attack any player character.

Other spit and polish:

* New Level/Level Properties UI reworked into a magicform.
* New "PromptPre(question, answer, func)" function for prompting the
  user with the developer shell, but pre-filling in an answer for them
  to either post or edit.
* magicform has a PromptUser field option for simple Text/Int fields
  which present as buttons, so magicform can prompt and update the
  variable itself.
* Don't show the _autosave.doodad in the Doodad Dropper window.

44122d4130 Spit and polish
UI improvements specifically for mobile (running the game with the
`-w mobile` or `-w landscape` options) screen sizes.

* Rework the Settings window to be mobile friendly to landscape
  oriented screens (`doodle -w landscape`) and migrate Options tab
  to magicform.
* The toolbar in the Editor will be a single column of buttons
  on small screens, such as `-w mobile` (375x812) portrait mode
  smartphone. On larger screens the toolbar shows in two columns
  of buttons.
* Fix tooltips not drawing on top.
* Centralize the hard-coded references to specific font filenames
* Add cheat code: `test load screen` to bring a sample loading screen up
  for a few seconds. It needs improvement on `-w landscape`

77297fd60d Text Tool and Pan Tool
Two new tools added to the Level Editor:

* Pan Tool: left-click to scroll the level around safely.
* Text Tool: write text onto your level.

Features of the Text Tool:

* Can choose from the game's built-in fonts, size and enter the message
  you want to write.
* The mouse cursor previews the text when hovered over the level.
* Click to "stamp" the text onto your level. The currently selected
  color swatch will be used to color the text in.
* Adds two new fonts: Azulian.ttf and Rive.ttf that can be selected in
  the Text Tool.

Some implementation notes:

* Added package native/engine_sdl.go that handles the lower-level
  SDL2_TTF logic to rasterize the text into a black&white image.
* WASM not supported yet (if the game even still built for WASM);
  native/engine_wasm.go stubs out the TextToImage() call with a "not
  supported" error just in case.

Other changes:

* New Toolbar icons: they are 24x24 instead of 32x32 to make more room
  for more tools.
* The toolbar now shows two buttons per row for a more densely packed
  layout. For very narrow screen widths (< 600px) the default Vertical
  Toolbar layout will use one-button-per-row to not eat too much screen
  real estate.
* In the Horizontal Toolbars layout there are 2 buttons per column.
2022-03-05 15:34:20 -08:00
1205dc2cd3 Invulnerable Anvil and other fixes
* Add methods `Invulnerable() bool` and `SetInvulnerable(bool)` to the
  Actor API accessible in JavaScript (e.g. `Self.SetInvulnerable(true)`)
* The Anvil is invulnerable - when played as, it can crush other mobs by
  jumping on them but is not defeated by those mobs at the same time.
* Anvils don't destroy invulnerable mobs, such as other Anvils.
* Bugfix: the Electric Door is considered to be opened from the first
  frame of animation when the door begins opening, and remains opened
  until the final frame of animation when it is closing.
* New cheat code: `megaton weight` to play as the Anvil by default.

4de0126b19 Game Controller Support
Adds support for Xbox and Nintendo style game controllers. The gamepad
controls are documented on the README and in the game's Settings window.

The buttons are not customizable yet, except that the player can choose
between two button styles:

* X Style (default): "A" button is on the bottom and "B" on the right.
* N Style: swaps the A/B and the X/Y buttons to use a Nintendo-style
  layout instead of an Xbox-style.

626fd53a84 Checkpoint Flag can Re-assign Player Character
Link a Doodad to a Checkpoint Flag (like you would a Start Flag) and
crossing the flag will replace the player with that doodad. Multiple
checkpoint flags like this can toggle you between characters.

* Azulians are now friendly to player characters who have the word
  "Azulian" in their title.
* Improve Bird as the playable character:
  * Dive animation if the player flies diagonally downwards
  * Animation loop while hovering in the air instead of pausing
* Checkpoint flags don't spam each other on PubSub so much which could
  sometimes lead to deadlocks!

SetPlayerCharacter added to the JavaScript API. The Checkpoint Flag
(not the region) can link to a doodad and replace the player character
with that linked doodad when you activate the checkpoint:

    Actors.SetPlayerCharacter(filename string): like "boy.doodad"

Add various panic catchers to make JavaScript safer and log issues
to console.
2022-01-18 21:24:36 -08:00
9201475060 Update Doodad JS API + Hostile mobs
New functions are available on the JavaScript API for doodads:

* Actors.At(Point) []*Actor: returns actors intersecting a point
* Actors.FindPlayer() *Actor: returns the nearest player character
* Actors.New(filename string): create a new actor (NOT TESTED YET!)
* Self.Grounded() bool: query the grounded status of current actor

With this the game's built-in doodads have been revised:

* Bird: will now scan 240 pixels diagonally searching for the player
  character and will dive if seen. The Bird is dangerous while
  diving. It will return to its original altitude once it touches
  the ground.
* Azulians: the Azulians are now dangerous to player characters but
  not to the Thief. Azulians will begin to follow the player when
  they are within the aggro range and will hop if the player is
  above them to try and overcome obstacles.
  * Blue Azulian: aggro is (250, 100) jump speed 12 movement 2
  * Red Azulian: aggro is (250, 200) jump speed 14 movement 4

1cc6eee5c8 Refactor Level Publishing + MagicForm
* magicform is a helper package that may eventually be part of the go/ui
  library, for easily creating structured form layouts.
* The Level Publisher UI is the first to utilize magicform.

Refactor how level publishing works:

* Level data now stores SaveDoodads and SaveBuiltins (bools) and when
  the level editor saves the file, it will attach custom and/or builtin
  doodads just before save.
* Move the menu item from the File menu to Level->Publish
* The Publisher UI just shows the checkboxes to toggle the level
  settings and a convenient Save button along with descriptive text.
* Free versions get the "Register" window popping up if they click the
  Save Now button from within the publisher window.

Note: free versions can still toggle the booleans on/off but their game
will not attach any new doodads on save.

* Free games which open a level w/ embedded doodads will get a pop-up
  warning that the doodads aren't available.
* If they DON'T turn off the SaveDoodads option, they can still edit and
  save the level and keep the existing doodads attached.
* If they UNCHECK the option and save, all attached doodads are removed
  from the level.

4d08bf1d85 Switch JavaScript engine to goja
* Switch from otto to goja for JavaScript engine.
* goja supports many ES6 syntax features like arrow functions,
  const/let, for-of with more coming soon.
* Same great features as otto, more modern environment for doodads!

9e4f34864d Remove MsgPack, Fix doodad display on top/left edges
* Clean up unused msgpack code for levels and doodads
* Fix the cosmetic bug where actors in your level would display wrongly
  when scrolling off the top/left edges of the screen: they used to
  anchor at their own 0,0 coordinate and crop their width/height leading
  to a 'scrolling' effect that didn't happen on the right/bottom edges.

ddf0074099 Condensed Palette, Bird AI Update
* The Red Bird now records its original altitude on the level and will
  try and return there should it accidentally climb up or down a wall.
  Sometimes goes into a wavy pattern surrounding its original altitude.
* Editor UI: in the default (vertical) toolbar, the Palette now has a
  two column view to show more color choices on screen at once.
* User setting added: hide the touch control hints.
