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.

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"

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
24aef28a0d Centralize Keybinds, Improve Menus
* pkg/keybinds holds central functions to check global keybinds, like
  DebugOverlay (F3), Undo (Ctrl-Z), GotoPlay/GotoEdit (p/e), etc.
* The Tools menu in the editor mode lists out more options to select
  various drawing tools (line, pencil, etc.) - and showing the hotkey
  for each tool.
2020-11-17 18:22:48 -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
f0101ba048 The Window Manager Update
* Take advantage of the new Window Manager feature of the UI toolkit.
* Move the MenuScene's "New Level" and "Play/Edit Level" windows into
  stand-alone functions in new pkg/windows/ package. The 'windows'
  package is isolated from the rest of Doodle and communicates using
  config variables and callback functions to avoid circular dependency.
* MenuScene calls the window constructors from the new package.
* Add an "Options" button to the Menu Bar in the Editor Scene, which
  opens the "New Level" window to allow changing the wallpaper or
  bounding type of the level currently being edited.
* Move the cheat codes into their own file, cheats.go

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
f8ca9a0921 Tooltips Update
* Update code for recent changes in UI toolkit around event handlers for
  buttons.
* Add tooltips to various buttons in the Editor Mode. The left toolbar
  shows the names of each tool, the Doodad Palette shows the title of
  each doodad and the Color Palette shows the swatch attributes (solid,
  fire, water, etc.)
2020-03-09 22:22:22 -07:00
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.

a43e45fad0 Level Collision and Scrolling Fixes
* Fix the level collision bug that allowed clipping thru a ceiling while
  climbing up a wall.
* Fix the scrolling behavior to keep the character on-screen no matter
  how fast the character is moving, especially downwards.
* Increase player speed and gravity.
* New cheat: "ghost mode" disables clipping for the player character.
* Mark an actor as "grounded" if they fall and are stopped by the lower
  level border, so they may jump again.

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.

7355778a39 render: Refactor Events System to Make Module Standalone
* Refactor the events used in lib/render/sdl to be more general-purpose
  to make librender a stand-alone library separate from Doodle.

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.

6476a67faf Make Fire Deadly
* Touching "fire" pixels in a level will pop up the End Level alert box
  saying you've died by fire and can restart the level.
* Update level.WriteFile() to prune broken links between actors before
  save. So when a linked actor is deleted, the leftover link data is
  cleaned up.
* Slight optimization in Canvas.drawStrokes: if either end of the stroke
  is not within view of the screen, don't show the stroke.
2019-07-06 20:31:50 -07:00
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.
2019-07-05 15:02:22 -07:00
c8620f871e Drawing Strokes and Undo/Redo Functionality
* Add new pkg/drawtool with utilities to abstract away drawing actions
  into Strokes and track undo/redo History for them.
* The freehand Pencil tool in EditorMode has been refactored to create a
  Stroke of Shape=Freehand and queue up its world pixels there instead
  of directly modifying the level chunker in real time. When the mouse
  button is released, the freehand Stroke is committed to the level
  chunker and added to the UndoHistory.
* UndoHistory is (temporarily) stored with the level.Level so it can
  survive trips to PlayScene and back, but is not stored as JSON on
  disk.
* Ctrl-Z and Ctrl-Y in EditorMode for undo and redo, respectively.
2019-07-03 16:25:23 -07:00
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.
2019-07-02 15:24:46 -07:00
b17ca34de2 Bindata: Embedding Doodads and Levels (for WASM)
* Use `go-bindata` to embed built-in doodads and levels directly into
  the Doodle binary. `make bindata` produces the bindata source file.
* Add `FromJSON()` method to Levels and Doodads to load objects from
  JSON strings in memory (for bindata built-ins or WASM ajax requests)
* Update file loading functions to check the embedded bindata files.
  * pkg/config.go#EditFile:
    * Supports editing a level from bindata (TODO: remove this support)
    * If the "assets/levels/%(simple-name.level)" exists in bindata,
      edits that drawing.
    * No such support for editing built-in doodads.
    * WASM has no filesystem access to edit files except built-in
      levels (yet)
  * pkg/doodads#ListDoodads:
    * Prepends built-in doodads from bindata to the returned list.
    * WASM: no filesystem access so gets only the built-ins.
  * pkg/doodads#LoadFile:
    * Checks built-in bindata store first for doodad files.
    * WASM: tries an HTTP request if not found in bindata but can go no
      further if not found (no filesystem access)
  * pkg/filesystem#FindFile:
    * This function finds a level/doodad by checking all the places.
    * If the level or doodad exists in bindata built-in, always returns
      its system path like "assets/doodads/test.doodad"
    * WASM: always returns the built-in candidate path even if not found
      in bindata so that ajax GET can be attempted.
  * pkg/level#ListSystemLevels:
    * New function that lists the system level files, similar to the
      equivalent doodads function.
    * Prepends the bindata built-in level files.
    * WASM: only returns the built-ins (no filesystem support)
    * Desktop: also lists and returns the assets/levels/ directory.
  * pkg/level#LoadFile:
    * Like the doodads.LoadFile, tries from built-in bindata first, then
      ajax request (WASM) before accessing the filesystem (desktop)
* Menu Scene: TODO, list the built-in levels in the Load Level menu.
  This feature will soon go away when WASM gets its own storage for user
  levels (localStorage instead of filesystem)
2019-06-27 15:07:34 -07:00
9efe16582c Add Play/Edit Buttons to Toggle Between Modes
* Instead of needing to press the "P" and "E" keys to toggle from edit
  mode to play mode (and back again), respectively, the UI now draws a
  "Play (P)" or "Edit (E)" button on the bottom right corner of the
  level canvas. Clicking it will toggle the mode.
2019-06-25 18:36:53 -07:00
4dd1bebc5f Add MenuScene with New Level UI
* Debug mode: no longer enables the DebugOverlay (F3) by default, but
  does now insert the current FPS counter into the window title bar.
* ui.Frame: set a default "mostly transparent" BG color so the frame
  background doesn't render as white.
* Add the MenuScene which will house the game's main menus.
* The "New Level" menu is first to be added.
  * UI lets you pick Page Type and Wallpaper using radio buttons.
  * Page Type: Unbounded, Bounded (default), No Negative Space, Bordered
  * Fix bugs in uix.Canvas to fully support all these page types.
2019-06-25 15:01:37 -07:00
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.

f76ba6fbb7 WIP: MsgPack stubs, Level Filesystem Module
* Add some encoding/decoding functions for binary msgpack format for
  levels and doodads. Currently it writes msgpack files that can be
  decoded and printed by Python (mp2json.py) but it can't re-read from
  the binary format. For now, levels will continue to write in JSON
  format.
* Add filesystem abstraction functions to the balance/ package to search
  multiple paths to find Levels and Doodads, to make way for
  system-level doodads.

258b2eb285 Script Timers, Multiple Doodad Frames
* CLI: fix the `doodad convert` command to share the same Palette when
  converting each frame (layer) of a doodad so subsequent layers find
  the correct color swatches for serialization.
* Scripting: add timers and intervals to Doodad scripts to allow them to
  animate themselves or add delayed callbacks. The timers have the same
  API as a web browser: setTimeout(), setInterval(), clearTimeout(),
  clearInterval().
* Add support for uix.Actor to change its currently rendered layer in
  the level. For example a Button Doodad can set its image to Layer 1
  (pressed) when touched by the player, and Trapdoors can cycle through
  their layers to animate opening and closing.
  * Usage from a Doodad script: Self.ShowLayer(1)
* Default Doodads: added scripts for all Buttons, Doors, Keys and the
  Trapdoor to run their various animations when touched (in the case of
  Keys, destroy themselves when touched, because there is no player
  inventory yet)
2019-04-18 18:15:05 -07:00
1e80304061 Initial Doodad JavaScript System
* Add the JavaScript system for Doodads to run their scripts in levels,
  and wire initial OnCollide() handler support.
* CLI: Add a `doodad install-script` command to the doodad tool.
  * Usage: `doodad install-script <index.js> <filename.doodad>`
* Add dev-assets folder for storing source files for the official
  default doodads, sprites, levels, etc. and for now add a JavaScript
  for the first test doodad.

241186209c Play Mode: Fix Level Collision w/ Scrolling
Fixes:
* Move the call to CollidesWithGrid() inside the Canvas instead of
  outside in the PlayScene.movePlayer() so it can apply to all Actors
  in motion.
* PlayScene.movePlayer() in turn just sets the player's Velocity so the
  Canvas.Loop() can move the actor itself.
* When keeping the player inside the level boundaries: previously it was
  assuming the player Position was relative to the window, and was
  checking the WorldIndexAt and getting wrong results.
* Canvas scrolling (loopFollowActor): check that the actor is getting
  close to the screen edge using the Viewport into the world, NOT the
  screen-relative coordinates of the Canvas bounding boxes.
