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.

a112c19d76 Few small tweaks 2021-10-09 21:22:50 -07:00
1a8a5eb94b Polish and bugfixes
- Fix a memory sharing bug in the Giant Screenshot feature.
- Main Menu to eagerload chunks in the background to make scrolling less
  jittery. No time for a loadscreen!
- Extra script debugging: names/IDs of doodads are shown when they send
  messages to one another.
- Level Properties: you can edit the Bounded max width/height values for
  the level.

Doodad changes:

- Buttons: fix a timing bug and keep better track of who is stepping on it,
  only popping up when all colliders have left. The effect: they pop up
  immediately (not after 200ms) and are more reliable.
- Keys: zero-qty keys will no longer put themselves into the inventory of
  characters who already have one except for the player character. So
  the Thief will not steal them if she already has the key.

Added to the JavaScript API:

* time.Hour, time.Minute, time.Second, time.Millisecond, time.Microsecond

e80a3f0446 Various minor tweaks and changes
* Recolor some of the region doodads
* Add command: `doodad edit-level --remove-actor` to remove actors from
  your level.
* Tweak the player jump velocity from playtesting levels.
2021-10-07 20:50:24 -07:00
d6acee5a66 Adjust Gravity and Prevent Moonwalking
* Tweak max gravity speed to match player max velocity.
* Boy's script watches for his velocity to flip suddenly and stops
  animations, limiting the moonwalking a bit.
* JS API: Self.GetVelocity() added.

55efdd6eb5 Technical Doodad: Checkpoint Region
The Checkpoint Region acts as an invisible checkpoint flag, remembering
the player's location should they need to respawn there.

New cheat: `show all actors` during Play Mode will make every hidden
actor visible. Useful to see your technical doodads during gameplay!

Developer shell: `Execute(command string)` is available to the
JavaScript interpreter. It simulates another command being run on the
developer console.

97e179716c Add Technical Doodads + UI Fixes
New category for the Doodad Dropper: "Technical"

Technical doodads have a dashed outline and label for now, and they
turn invisible on level start, and are for hidden technical effects on
your level.

The doodads include:

* Goal Region: acts like an invisible Exit Flag (128x128), the level is
  won when the player character touches this region.
* Fire Region: acts like a death barrier (128x128), kills the player
  when a generic "You have died!" message.
* Power Source: on level start, acts like a switch and emits a
  power(true) signal to all linked doodads. Link it to your Electric
  Door for it to be open by default in your level!
* Stall Player (250ms): The player is paused for a moment the first time
  it touches this region. Useful to work around timing issues, e.g.
  help prevent the player from winning a race against another character.

There are some UI improvements to the Doodad Dropper window:

* If the first page of doodads is short, extra spacers are added so the
  alignment and size shows correctly.
* Added a 'background pattern' to the window: any unoccupied icon space
  has an inset rectangle slot.
* "Last pages" which are short still render weirdly without reserving
  the correct height in the TabFrame.

Doodad scripting engine updates:

* Self.Hide() and Self.Show() available.
* Subscribe to "broadcast:ready" to know when the level is ready, so you
  can safely Publish messages without deadlocks!

c499a15c71 Animations for Thief + No More Moonwalking
* Adds walking animations for the Thief.
* Mobile doodads no longer moonwalk: their A.I. used to wait for the
  animation to finish before setting the appropriate animation, so when
  it changed directions it would "moonwalk" for a time. Their A.I. is
  now updated to cancel the animation if they change directions so to
  immediately play the correct animation.

0fa1bf8a76 Editor: Doodad Properties Window
The Doodad Properties window brings many features that used to be
available only in the `doodad` CLI tool into the Doodad Editor.

* In the Doodad Editor there is a new menubar item: "Doodad" which
  corresponds to the "Level" menu when you're editing a level.
* The "Doodad" menu has two items:
  - "Doodad Properties" (NEW)
  - "Layers" (moved here from the Tools menu)
* The Doodad Properties window lets you edit the Title and Author values
  of the doodad, as well as modify its Tags and manage its Script.
* Its script can be attached (browse for .js file on disk), its existing
  script saved back to disk (dev shell prompt) or deleted altogether
  from the doodad.
* You can create, modify, and delete Tags on the doodad.

Other changes:

* In the Level Editor, the "Level->Page Settings" menu is renamed to
  "Level->Level Properties" to match with "Doodad->Doodad Properties"
  and the pop-up window is retitled accordingly.
* The Exit Flag only exits if the Player touches it - not just any
  mobile doodad!

1ac85c9297 Checkpoint Flag & Retry from Checkpoint
* New Doodad: Checkpoint Flag. They update the player's spawn point
  whenever the player passes one. The most recently activated
  checkpoint is rendered brighter than the others.
* End Level Modal: the fake alert box window drawn by the Play Mode
  is replaced with a fancy modal widget (similar to Alert and Confirm).
  It handles level victory or failure conditions and can show or hide
  all the buttons as needed.
* Gameplay: There is a "Retry from Checkpoint" option added, which
  appears in the level failure modal. It will teleport you back to
  the Start Flag or the last Checkpoint Flag you had touched, without
  resetting the level -- your keys, unlocked doors, etc. will be
  preserved so you can retry.
* Set a maximum speed on the "Camera Follows Actor" logic of 64
  pixels per tick. This results in a smoother scrolling transition
  when the player jumps to a new location on the map, such as by
  a Warp Door.
* Update the default color palettes:
    * All: Add a "hint" magenta color.
    * Colored Pencil: Add a "darkstone" solid color.

Updates to the Doodads JavaScript API:

* SetCheckpoint(Point(x, y)): set the player character's spawn
  position. Giving it Self.Position() is an easy way to set the
  player spawn to your doodad's location.

43f8e3d9b2 Thief: Ability to Steal as Player Character
* The Thief's ability is now available to the player character in levels
  where you'll play as the Thief.
* The Thief is able to steal items from all characters it contacts,
  including Azulians and other Thieves.
* A.I. Thieves will not steal items from each other, to prevent loops.
  Only a Thief controlled by the player will steal items from a Thief.
2021-08-15 17:33:05 -07:00
405aaf509d Link Start Flags to Change Characters
New feature: link a Start Flag to another doodad in your level
and you will play as that doodad instead of Boy. All Creatures
are designed to be playable. Playing as "other" doodads leads
to interesting effects, like not being able to activate buttons,
switches, or warp doors and not having an inventory to pick up
keys. The Anvil is fun: it can destroy other mobile doodads by
jumping on them.

If the actor does not specify that it has gravity, the gameplay
starts in antigravity mode. This will be the vast majority of
non-mobile doodads and the Bird.

Other changes:

* The Blue and Red Azulians now share a doodad script.
* The Azulians AI is still to walk back and forth, pickup keys and
  press buttons. The Blue Azulian walks slower than the red one.
* The Blue Azulian is no longer hidden from the doodads list.
* Actor UUID values in levels are now V1 UUIDs (time-ordered).
  This will help to reliably resolve conflicts in draw order
  of overlapping doodads (newest added to level wins).
* Link Tool: clicking on a pair of already-linked doodads will
  now unlink them, so you don't have to delete one to delete
  the link.
* Actor Tool: deleting an actor immediately calls PruneLinks()
  to clean up any links that the deleted doodad might have.

d7a96d1770 Thief and Inventory APIs
This commit adds the Thief character with starter graphics
(no animations).

The Thief walks back and forth and will steal items from other
doodads, including the player. For singleton items that have no
quantity, like the Colored Keys, the Thief will only steal one
if he does not already have it. Quantitied items like the
Small Key are always stolen.

Flexibility in the playable character is introduced: Boy,
Azulian, Bird, and Thief all respond to playable controls.
There is not currently a method to enable these apart from
modifying balance.PlayerCharacterDoodad at compile time.

New and Changed Doodads

* Thief: new doodad that walks back and forth and will steal
  items from other characters inventory.
* Bird: has no inventory and cannot pick up items, unless player
  controlled. Its hitbox has also been fixed so it collides with
  floors correctly - not something normally seen in the Bird.
* Boy: opts in to have inventory.
* Keys (all): only gives themselves to actors having inventories.

JavaScript API - New functions available

* Self.IsPlayer() - returns if the current actor IS the player.
* Self.SetInventory(bool) - doodads must opt-in to having an
  inventory. Keys should only give themselves to doodads having
  an inventory.
* Self.HasInventory() bool
* Self.AddItem(filename, qty)
* Self.RemoveItem(filename, qty)
* Self.HasItem(filename)
* Self.Inventory() - returns map[string]int
* Self.ClearInventory()
* Self.OnLeave(func(e)) now receives a CollideEvent as parameter
  instead of the useless actor ID. Notably, e.Actor is the
  leaving actor and e.Settled is always true.

Other Changes

* Play Mode: if playing as a character which doesn't obey gravity,
  such as the bird, antigravity controls are enabled by default.
  If you `import antigravity` you can turn gravity back on.
* Doodad collision scripts are no longer run in parallel
  goroutines. It made the Thief's job difficult trying to steal
  items in many threads simultaneously!
2021-08-09 22:42:22 -07:00
0518df226c New Doodad: Anvil
* The Anvil doodad is affected by gravity and becomes dangerous when
  falling. If it lands on the player character, you die! If it lands on
  any other mobile doodad, it destroys it! It can land on solid doodads
  such as the Electric Trapdoor and the Crumbly Floor. It will activate
  a Crumbly Floor if it lands on one, and can activate buttons and
  switches that it passes.
* JavaScript API: FailLevel(message) can be called from a doodad to kill
  the player character. The Anvil does this if it collides with the
  player while it's been falling.
2021-08-08 21:57:41 -07:00
810ba193d9 Doodads: Electric Trapdoor and Resettable Box
* New doodad: Electric Trapdoor. It is a horizontal version of the
  Electric Door. Opens while powered by a button or a switch and closes
  when it loses power.
* The Box doodad will reset to its original location if it receives a
  power signal from a linked Button or Switch. So for box pushing
  puzzles you can add a reset button in case the boxes get stuck.
* Refactored the Doodad build scripts into many Makefiles for easier
  iteration (don't need to compile ALL doodads to test one).

Updates to the JavaScript API for doodads:

* Self.MoveTo(Point) is now available to set the actor's position in
  world coordinates.
2021-08-08 20:10:42 -07:00
49876c4fdf New TabFrame Widget for Doodads and Settings
* Install the new ui.TabFrame widget into the Settings and Doodad
  Dropper windows to give them properly tabbed interfaces.
* Doodad Dropper's new tabs divide the list of doodads into categories
  to make them easier to find.
* The officially defined categories so far are:
  - Objects (Start/End Flags and Box)
  - Doors (All locked doors and keys, Warp Doors, and Electric Door)
  - Gizmos (All buttons, switches, state blocks/doors, Electric Door)
  - Creatures (Blue/Red Azulian, Bird, Boy)
* The "All" tab of the Doodad Dropper will show every doodad regardless
  of its category or whether it fit one of the official categories.
* How doodads are assigned categories is by a special "category" tag in
  their metadata, e.g. "category=doors,gizmos" - multiple supported.

3949934bc1 Prepare v0.7.2 for release 2021-07-19 21:20:22 -07:00
2d1b926e4f New Doodad: Box
The Box can be pushed around by the player or other mobile doodads.

It is affected by gravity and can be pushed off ledges.

If the player gets under a box they can bump it up with their head.
2021-07-18 21:22:53 -07:00
d14eaf7df2 Collision Box Updates
* The F4 key to draw collision boxes works reliably again: it draws the
  player's hitbox in world-space using the canvas.DrawStrokes()
  function, rather than in screen-space so it follows the player
  reliably.
* The F4 key also draws hitboxes for ALL other actors in the level:
  buttons, enemies, doors, etc.
* The level geometry collision function is updated to respect a doodad's
  declared Hitbox from their script, which may result in a smaller box
  than their raw Canvas size. The result is tighter collision between
  doodads, and Boy's sprite is rather narrow for its square Canvas so
  collision on rightward geometry is tighter for the player character.
* Collision checks between actors also respect the actor's declared
  hitboxes now, allowing for Boy to get even closer to a locked door
  before being blocked.
2021-06-02 20:50:28 -07:00
76b7dfa4f8 Various updates
New doodad interactions:
* Sticky Buttons will emit a "sticky:down" event to linked doodads, with
  a boolean value showing the Sticky Button's state.
* Normal Buttons will listen for "sticky:down" -- when a linked Sticky
  Button is pressed, the normal Button presses in as well, and stays
  pressed while the sticky:down signal is true.
* When the Sticky Button is released (e.g. because it received power
  from another doodad), any linked buttons which were sticky:down
  release as well.
* Switch doodads emit a new "switch:toggle" event JUST BEFORE sending
  the "power" event. Sensitive Doodads can listen for switches in
  particular this way.
* The Electric Door listens for switch:toggle; if a Switch is activated,
  the Electric Door always flips its current state (open to close, or
  vice versa) and ignores the immediately following power event. This
  allows doors to toggle on/off regardless of sync with a Switch.

Other changes:
* When the player character dies by fire, instead of the message saying
  "Watch out for fire!" it will use the name of the fire swatch that
  hurt the player. This way levels could make it say "Watch out for
  spikes!" or "lava" or whatever they want. The "Fire" attribute now
  just means "instantly kills the player."
* Level Editor: You can now edit the Title and Author name of your level
  in the Page Settings window.
* Bugfix: only the player character ends the game by dying in fire.
  Other mobile doodads just turn dark but don't end the game.
* Increase the size of Trapdoor doodad sprites by 150% as they were a
  bit small for the player character.
* Rename the game from "Project: Doodle" to "Sketchy Maze"
2021-03-30 23:40:41 -07:00
837960c477 Doodads: Small Key Door + Bigger Crumbly Floor
* The crumbly floor doodad was made 50% larger.
* New doodad: Small Key and Small Key Door. These work like the colored
  doors and locks except each Small Key is consumed when it unlocks a
  door. The door's appearance is of iron bars.
* The inventory HUD displays a small quantity label in the lower-right
  corner of items that have a quantity, such as the Small Key. This is
  done as a Canvas.CornerLabel string attribute on uix.Canvas.
* The "give all keys" cheat adds 99 Small Keys to your inventory.
2021-01-03 17:06:33 -08:00
3892087932 Doodads: Use Key and Working Warp Doors
* The "Use Key" (Q or Spacebar) now activates the Warp Door instead of a
  collision event doing so.
* Warp Doors are now functional: the player opens a door, disappears,
  the door closes; player is teleported to the linked door which opens,
  appears the player and closes.
* If the player exits thru a Blue or Orange door which is disabled
  (dotted outline), the door still opens and drops the player off but
  returns to a Disabled state, acting as a one-way door.
* Clean up several debug log lines from Doodle and doodad scripts.
2021-01-03 15:19:21 -08:00
2c1185cc9f Doodads: Warp Doors, Bird, Larger State Blocks
* The blue and orange ON/OFF state blocks have all been increased in
  size to better match the player character (42x42 up from 33x33)
* Added a new mob: the Red Bird. It flies back and forth while
  maintaining its altitude, similar to the Red Azulian. Planned AI
  behavior is to divebomb the player when it gets close. Dive sprites
  are included but not yet hooked up in JavaScript.
* Warp Doors! (WIP). They have a golden "W" on them and come in three
  varieties: Brown, Blue and Orange. The blue and orange ones are
  sensitive to the State Block and will become dotted outlines when
  inactive (and can not be entered in this state). The door opens for
  the player character, makes him disappear, then closes again. The plan
  is it will then warp you to the location of a linked Warp Door
  elsewhere on the level, but for now it will just make the player
  re-appear after completing the Close Door animation.
2020-12-29 20:31:35 -08:00
11afc7b522 New Doodads: Bigger Doors
* The colored locked doors and the Electric Door are increased in size
  to better match Boy's sprite size.
* Colored doors now have a "locked" and "unlocked" state when closed;
  when locked, a gold padlock hangs on the door with a keyhole shaped to
  match the corresponding Colored Key.
2020-12-29 17:24:42 -08:00
71b3eafbe4 Add Player Character Sprites
* Added initial walking sprites for the player character, "Boy."
* Player doodad filename and title screen level are now configurable in
  the balance/numbers.go package.
2020-09-18 22:35:43 -07:00
27896a9253 Add Initial Sound Effects
Adds support for sound effects in Doodle and configures some for various
doodads to start out with:

* Buttons and Switches: "Clicked down" and "clicked up" sounds.
* Colored Doors: an "unlocked" sound and a "door opened" sound.
* Electric Door: sci-fi sounds when opening and closing.
* Keys: sound effect for collecting keys.

JavaScript API for Doodads adds a global function `Sound.Play(filename)`
to play sounds. All sounds in the `rtp/sfx/` folder are pre-loaded on
startup for efficient use in the app. Otherwise sounds are lazy-loaded
on first playback.
2020-05-22 20:07:48 -07:00
38614ee280 Tighten Doodad JavaScript API, User Documentation
* Tightens up the surface area of API methods available to the
  JavaScript VMs for doodads. Variables and functions are carefully
  passed in one-by-one so the doodad script can only access intended
  functions and not snoop on undocumented APIs.
* Wrote tons of user documentation for Doodad Scripts: documented the
  full surface area of the exposed JavaScript API now that the surface
  area is known and limited.
* Early WIP code for the Campaign JSON
2020-04-21 23:50:45 -07:00
08e65c32b5 Overhaul the Platformer Physics System
* Player character now experiences acceleration and friction when
  walking around the map!
* Actor position and movement had to be converted from int's
  (render.Point) to float64's to support fine-grained acceleration
  steps.
* Added "physics" package and physics.Vector to be a float64 counterpart
  for render.Point. Vector is used for uix.Actor.Position() for the sake
  of movement math. Vector is flattened back to a render.Point for
  collision purposes, since the levels and hitboxes are pixel-bound.
* Refactor the uix.Actor to no longer extend the doodads.Drawing (so it
  can have a Position that's a Vector instead of a Point). This broke
  some code that expected `.Doodad` to directly reference the
  Drawing.Doodad: now you had to refer to it as `a.Drawing.Doodad` which
  was ugly. Added convenience method .Doodad() for a shortcut.
* Moved functions like GetBoundingRect() from doodads package to
  collision, where it uses its own slimmer Actor interface for just the
  relevant methods it needs.
2020-04-04 21:00:32 -07:00
c3d7348843 Inventory System for Level Actors
* Added an inventory system for actors as a replacement to the arbitrary
  key/value data store. Colored keys now add themselves to the player's
  inventory, and colored doors check the inventory.
* Inventory is a map[string]int between doodad filenames
  (red-key.doodad) and quantity (0 for key items/unlimited qty).
* API methods to add and remove inventory.
* Items HUD appears in Play Mode in lower-left corner showing doodad
  sprites of all the items in the Player's inventory.
2020-04-02 23:09:46 -07:00
3cb99ad5f8 New (Colored) Locked Door Doodads
* Revamped the sprites for the four colored locked doors. They now have
  a side-view profile perspective rather than a front view.
* Doors open facing the left or the right based on what direction the
  colliding actor approached it from.

b4922edf5d Doodad Tool: Add Tag Support for edit-doodad
* The `doodad edit-doodad` command now allows setting custom key/value
  tags in doodad files, for extra data storage useful to their scripts.
* Colored keys and doors now store a `color` tag with the appropriate
  color so that their scripts don't have to parse their Title to find
  that information.
* Trapdoors now store a `direction` tag to hold the direction the door
  is facing.
2020-01-02 22:12:20 -08:00
0e3a30e633 Fix Actor Collision Checks Again
* Recent collision update caused a regression where the player would get
  "stuck" while standing on top of a solid doodad, unable to walk left
  or right.
* When deciding if the actor is on top of a doodad, use the doodad's
  Hitbox (if available) instead of the bounding box. This fixes the
  upside-down trapdoor acting solid when landed on from the top, since
  its Hitbox Y coordinate is not the same as the top of its sprite.
* Cheats: when using the noclip cheat in Play Mode, you can hold down
  the Shift key while moving to only move one pixel at a time.
2020-01-02 22:05:49 -08:00
7b3aec0fef Fix Two-State Blocks & Collision Detection
* Two-state Buttons now also subscribe to the state change message, so
  other on/off buttons in the same level update to match the state of
  the button that was hit.
* Add lock mutexes around the scripting engine to protect from
  concurrent event handlers.
2020-01-02 17:58:22 -08:00
8965a7d86a Doodads: Crumbly Floor, Start Flag & State Blocks
Add new doodads:

* Start Flag: place this in a level to set the spawn point of the player
  character. If no flag is found, the player spawns at 0,0 in the top
  corner of the map. Only use one Start Flag per level, otherwise the
  player will randomly spawn at one of them.
* Crumbly Floor: a solid floor that begins to shake and then fall apart
  after a moment when a mobile character steps on it. The floor respawns
  after 5 seconds.
* State Blocks: blue and orange blocks that toggle between solid and
  pass-thru whenever a State Button is activated.
* State Button: a solid "ON/OFF" block that toggles State Blocks back
  and forth when touched. Only activates if touched on the side or bottom;
  acts as a solid floor when walked on from the top.

New features for doodad scripts:

* Actor scripts: call SetMobile(true) to mark an actor as a mobile mob
  (i.e. player character or enemy). Other doodads can check if the actor
  colliding with them IsMobile so they don't activate if placed too close
  to other (non-mobile) doodads in a level. The Blue and Red Azulians
  are the only mobile characters so far.
* Message.Broadcast allows sending a pub/sub message out to ALL doodads
  in the level, instead of only to linked doodads as Message.Publish does.
  This is used for the State Blocks to globally communicate on/off status
  without needing to link them all together manually.

65a811db0d Auto-prune Empty Chunks in Level Files
* Discovered a bug where if you hit the Undo key to erase pixels and an
  entire chunk became empty by it, the chunk would have rendering errors
  and show as a solid black square instead of the level wallpaper
  showing through.
* Chunks that have no pixels in them are culled from the chunker
  immediately when you call a Delete() operation.
* The level file saver also calls a maintenance function to prune all
  empty chunks upon saving the file. So existing levels with broken
  chunks need only be re-saved to fix them.
2019-07-16 22:10:18 -07:00
6af60f1128 Improve Collision Detection: More Active w/ Actors
* Improve the collision detection algorithm so that Actor OnCollide
  scripts get called more often WHILE an actor is moving, to prevent a
  fast-moving actor from zipping right through the "solid" hitbox and
  not giving the subject actor time to protest the movement.
* It's implemented by adding a `Settled` boolean to the OnCollide event
  object. When the game is testing out movement, Settled=false to give
  the actor a chance to say "I'm solid!" and have the moving party be
  stopped early.
* After all this is done, for any pair of actors still with overlapping
  hitboxes, OnCollide is called one last time with Settled=true. This is
  when the actor should run its actions (like publishing messages to
  other actors, changing state as in a trapdoor, etc.)
* The new collision detection algorithm works as follows:
  * Stage 1 is the same as before, all mobile actors are moved and
    tested against level geometry. They record their Original and New
    position during this phase.
  * Stage 2 is where we re-run that movement but ping actors being
    intersected each step of the way. We trace the steps between
    Original and New position, test OnCollide handler, and if it returns
    false we move the mobile actor to the Last Good Position along the
    trace.
  * Stage 3 we run the final OnCollide(Settled=true) to let actors run
    actions they wanted to for their collide handler, WITHOUT spamming
    those actions during Stage 2.
* This should now allow for tweaking of gravity speed and player speed
  without breaking all actor collision checking.

154fc6c9cb Update Doodad build-scripts to tag extra data
* The Blue Azulian marks its doodad file as Hidden.
* All Doodads are write locked after generation and tagged with common
  author value.

cb02feff1d Add Switches, Fire/Water Collision and Play Menu
* New doodads: Switches.
  * They come in four varieties: wall switch (background element, with
    "ON/OFF" text) and three side-profile switches for the floor, left
    or right walls.
  * On collision with the player, they flip their state from "OFF" to
    "ON" or vice versa. If the player walks away and then collides
    again, the switch flips again.
  * Can be used to open/close Electric Doors when turned on/off. Their
    default state is "off"
  * If a switch receives a power signal from another linked switch, it
    sets its own state to match. So, two "on/off" switches that are
    connected to a door AND to each other will both flip on/off when one
    of them flips.
* Update the Level Collision logic to support Decoration, Fire and Water
  pixel collisions.
  * Previously, ALL pixels in the level were acting as though solid.
  * Non-solid pixels don't count for collision detection, but their
    attributes (fire and water) are collected and returned.
* Updated the MenuScene to support loading a map file in Play Mode
  instead of Edit Mode. Updated the title screen menu to add a button
  for playing levels instead of editing them.
* Wrote some documentation.

dc2695cfc9 Add More Trapdoor Doodads
* Add the other trapdoor directions: Left, Right and Up.
* UI: Show a color square in each Palette Swatch button in Edit Mode.
  * Instead of just the label like "solid", "fire", "decoration" it also
    shows a square box colored as the swatch color. The label and box
    are left-aligned in the button.
* Minor Play Mode physics update:
  * The player jump is now limited: they may only continue to move
    upwards for 20 ticks, after which they must touch ground before
    jumping again.
  * Remove the "press Down to move down" button. Only gravity moves you
    down.
* Fix a crash in the Editor Mode when you dragged doodads on top of each
  other. Source of bug was the loopActorCollision() function, which only
  should be useful to Play Mode, and it expected the scripting engine to
  be attached to the Canvas. In EditorMode there is no scripting engine.

0c22ecae5e Level Exit Doodad
* Add a Level Exit doodad, which for now is a little blue flag on a pole
  that reads "END"
* JavaScript API: global function EndLevel() will end the level. The
  exit doodad calls this when touched by the player.
* Add a "Level Completed" alert box UI to PlayScene with dynamic button
  layouts.
  * The alert box pops up when a doodad calls EndLevel() and contains
    action buttons what to do next.
  * "Play Again" restarts the current level again.
  * "Edit Level" if you came from the EditorScene; otherwise this button
    is not visible.
  * "Next Level" is a to-be-implemented button to advance in the single
    player story mode. Only shows up when PlayScene.HasNext=true.
  * "Exit to Menu" is always visible and closes out to the MainScene.

ba6892aa95 WASM Texture Caching
* Refactor texture caching in render.Engine:
  * New interface method: NewTexture(filename string, image.Image)
  * WASM immediately encodes the image to PNG and generates a JavaScript
    `Image()` object to load it with a data URI and keep it in memory.
  * SDL2 saves the bitmap to disk as it did before.
  * WASM: deprecate the sessionStorage for holding image data. Session
    storage methods panic if called. The image data is directly kept in
    Go memory as a js.Value holding an Image().
* Shared Memory workaround: the level.Chunk.ToBitmap() function is where
  chunk textures get cached, but it had no access to the render.Engine
  used in the game. The `pkg/shmem` package holds global pointers to
  common structures like the CurrentRenderEngine as a work-around.
  * Also shmem.Flash() so Doodle can make its d.Flash() function
    globally available, any sub-package can now flash text to the screen
    regardless of source code location.
  * JavaScript API for Doodads now has a global Flash() function
    available.
* WASM: Handle window resize so Doodle can recompute its dimensions
  instead of scaling/shrinking the view.

99eab19c5b Pub/Sub Messages Between Linked Actors (JavaScript)
* Implement the pub/sub message passing system that lets the JavaScript
  VM of one actor (say, a Button) send messages to other linked actors
  in the level (say, an Electric Door)
* Buttons now emit a "power(true)" message while pressed and
  "power(false)" when released. Sticky Buttons do not release and so do
  not send the power(false) message.
* Electric Doors listen for the "power" event and open or close
  themselves based on the boolean value received.
* If a Sticky Button receives power and is currently pressed down, it
  will pop back up (reset to "off" position) and notify its linked
  actors that they have lost power too. So if a Sticky Button held an
  Electric Door open, and another Button powers the Sticky Button, it
  would pop back up and also close the Electric Door.

567b3158f1 Minor Tweaks 2019-06-08 17:02:28 -07:00
1523deeb9c Return False: Solid Collision Between Actors
* Implement the handler code for `return false` when actors are
  colliding with each other and wish to act like solid walls.
* The locked doors will `return false` when they're closed and the
  colliding actor does not have the matching key.
* Add arbitrary key/value storage to Actors. The colored keys will set
  an actor value "key:%TITLE%" on the one who touched the key before
  destroying itself. The colored doors check that key when touched to
  decide whether to open.
* The trapdoor now only opens if you're touching it from the top (your
  overlap box Y value is 0), but if you touch it from below and the door
  is closed, it acts like a solid object.
2019-05-28 21:43:30 -07:00
a2e1bd1ccb Improve OnCollide Doodad Script Handling
* Events.OnCollide now receives a CollideEvent object, which makes
  available the .Actor who collided and the .Overlap rect which is
  zero-relative to the target actor. Doodad scripts can use the .Overlap
  to see WHERE in their own box the other actor has intruded.
  * Update the LockedDoor and ElectricDoor doodads to detect when the
    player has entered their inner rect (since their doors are narrower
    than their doodad size)
  * Update the Button doodads to only press in when the player actually
    touches them (because their sizes are shorter than their doodad
    height)
  * Update the Trapdoor to only trigger its animation when the board
    along its top has been touched, not when the empty space below was
    touched from the bottom.
* Events.OnLeave now implemented and fires when an actor who was
  previously intersecting your doodad has left.
* The engine detects when an event JS callback returns false.
  Eventually, the OnCollide can return false to signify the collision is
  not accepted and the actor should be bumped away as if they hit solid
  geometry.

d28745f89e Mobile Enemy Doodad Test
* Add a Red Azulian as a test for mobile enemies.
  * Its A.I. has it walk back and forth, changing directions when it
    comes up against an obstacle for a few moments.
  * It plays walking animations and can trigger collision events with
    other Doodads, such as the Electric Door and Trapdoor.
* Move Gravity responsibility to the doodad scripts themselves.
  * Call `Self.SetGravity(true)` to opt the Doodad in to gravity.
  * The canvas.Loop() adds gravity to any doodad that has it enabled.
