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.

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.

fc736abd5f Doodads: Gems, Snake and Crusher
Adds several new doodads to the game and 5 new wallpapers (parchment
paper in blue, green, red, white and yellow).

New doodads:

* Crusher: A purple block-headed mob wearing an iron helmet. It tries
  to crush the player when you get underneath. Its flat helmet can be
  ridden on like an elevator back up.
* Snake: A green stationary mob that always faces toward the player.
  If the player is nearby and jumps, the Snake will jump too and hope
  to catch the player in mid-air.
* Gems and Totems: A new key & lock collectible. Gems have quantity so
  you can collect multiple, and place them into matching Totems. A
  Totem gives off a power signal when its gem is placed and all other
  Totems it is linked to have also been activated. A single Totem may
  link to an Electric Door and require only one gem to open it, or it
  can link to other Totems and they all require gems before the power
  signal is sent out.

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).

402b5efa7e Zipfiles for Attached Files Too
* The level.FileSystem type has updated to support ZIP files too.
* Legacy levels loaded from gz/json have their old FileSystem as a
  simple map[filename]data and this parses from JSON OK.
* On save to zip, the legacy loaded file data gets exported to ZIP.
* Going forward: newly added or deleted files during runtime are kept in
  the legacy file map until the next save when the filemap is again
  flushed out to ZIP.
* For regular read-access, the FileSystem reads from the ZIP file if the
  data is not in the hot map (legacy file or recently modified
  attachment).
* Bugfix: be sure to Inflate() the Level/Doodad after loading from
  zipfile - it used to be that directly after a save, trying to play the
  level failed because the Level.Actors struct was missing their IDs,
  and similarly recently written chunks would error out (become black
  voids) on levels/doodads so we Inflate() both after save/replacing
  their zip handle.

302506eda9 Cheat: $ d.SetPlayerCharacter("anything.doodad")
Too restricted by the cheat codes to play as certain characters
on-demand? Use the JS shell in the developer console to set any doodad
you want:

    $ d.SetPlayerCharacter("key-blue")
    $ d.SetPlayerCharacter("anvil")
    $ d.SetPlayerCharacter("box.doodad")

The .doodad suffix is optional.

Interesting behaviors when playing as odd doodads:

* Most non-mobile doodads don't collide with each other, so you can pass
  through doors and not activate buttons if you play as a key or a
  trapdoor. Non-mobile doodads also generally have antigravity so you
  can fly freely around the map.
* Non-mobile doodads can not open Warp Doors or interact with the Exit
  Flag. You'll have to change back to a creature such as "boy" or
  "azu-blue" to win the level.
* If you are a key, the Thief can collect you! This removes your player
  doodad from the level and soft locks the game. No worries, another
  call to d.SetPlayerCharacter() will put you back on the map!
* If the doodad name isn't found, you'll play as the built-in fallback
  doodad, which is just a red "X" shape. It has anti-gravity and does
  not generally interact with any doodad (can not push buttons or
  collect keys - but it can pass through doors and other obstacles. Can
  not win the level goal flag, though!)

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.

d694fcc7c2 Fix climbing on the right bug + eager-render boolprop
* New boolProp to help debug memory issues: eager-render, set it to
  false and the loadscreen will not eagerload Go images for all the
  level chunks.
* Finally fix the level collision bug where the player could climb walls
  to the right.

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.

661c5f4365 Loadscreen Update & Window Resize Fixes
* Loadscreen: put the progress bar between the Title and Subtitle so it
  looks good even on mobile landscape orientation (narrow height)
* Bugfixes around window OnResize events: the loadscreen handles
  resizing correctly now and the Level Editor (or w/e) will also be the
  right size if you resized the window during loading.

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.

962098d4e7 v0.11.0 last minute tweaks
* When playing as the Bird, the dive attack is able to destroy other
  mobile doodads such as Azulians and Thieves.
* The Box has been made invulnerable so it can't be destroyed by Anvils
  or player-controlled Birds.
* Bugfixes with pop-up modals:
  * The quit game confirm modal doesn't appear if another modal is
    already active on screen.
  * The Escape key can dismiss Alert and Confirm modals.
* Add "Level" menu items to Play Mode to restart the level or retry from
  the last checkpoint (in case of softlocks, etc.)

40cb9f15cb Prepare v0.11.0 for release (+ fixes)

  no longer ships with the Tutorial levels in the "levels" folder as

  as a blank slate for only user levels.
* Add the Zoo level to the Tutorial levelpack
* Bugfixes around changing the player character to work around clipping
  issues if the character has changed height drastically.

293ac668e7 Azulian: Don't follow boring players
If the Azulians aren't hostile to the player character (e.g. you are
playing as a Thief or Azulian or you are invulnerable because you're the
Anvil), the Azulians won't aggro and pathfind to you either.
2022-02-20 12:19:56 -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.

The buttons are not customizable yet, except that the player can choose

* 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.

9201475060 Update Doodad JS API + Hostile mobs

* 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.

* New doodad: Invisible Warp Door
* All warp doors require the player to be grounded (if affected by
  gravity) to open them. No jumping or falling thru and opening
  a warp door mid-air!
* Title Screen now randomly selects from a couple of levels.
* Title Screen: if it fails to load a level it sets up a basic
  blank level with a wallpaper instead.
* New developer shell command: titlescreen <level>
  Opens the MainScene with a custom user level as the background.
* Add Auto-save to the Editor to save your drawing every 5 minutes
* Add a MenuBar to the Play Scene for easier navigation to other
  features of the game.
* Doodad JS API: time.Since() now available.

672ee9641a Savegame and High Scores
* Adds pkg/savegame to store user progress thru Level Packs.
* The savegame.json is mildly tamper resistant by including a checksum
  along with the JSON body.
* The checksum combines the JSON string + an app secret (in savegame.go)
  + user specific entropy (stored in their settings.json). If the user
  modifies their save file and the checksum becomes invalid the game
  will not load the save file, acting like it didn't exist, resetting
  all their high scores.

Updates to the Story Mode window:

* On the LevelPacks list: shows e.g. "[completed 0 of 3 levels]" showing
  a user's progress thru the level pack.
* Below the levels on the Detail screen:
  * Shows an indicator whether the level is completed or not.
  * Shows high scores (fastest times beating the level)
  * Shows a padlock icon if levels are locked and the player hasn't
    reached them yet. Pops up an Alert modal if a locked level is
    clicked on.

Scoring is based around your fastest time elapsed to finish the level.

* Perfect Time (gold coin): player has not died during the level.
* Best Time (silver coin): player has continued from a checkpoint.

In-game an elapsed timer is shown in the top left corner along with the
gold or silver coin indicating if your run has been Perfect.

If the user enters any Cheat Codes during gameplay they are not eligible
to win a high score, but the level will still be marked as completed.
The icon next to the in-game timer disappears when a cheat code has been
entered.
