Noah Petherbridge 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.

Constants and settings for the Doodle app.

Environment Variables

Some runtime settings can be configured in the environment. Here they are with their default values.

Most colors work with alpha channels; just provide an 8 hex character code, like #FF00FF99 for 153 ($99) on the alpha channel.

  • Application Windw Size (ints):
    • DOODLE_W=1024
    • DOODLE_H=768
  • Shell settings:
    • D_SHELL_BG=#001428C8: shell background color.
    • D_SHELL_FG=#0099FF: shell text color.
    • D_SHELL_PC=#FFFFFF: shell prompt color.
    • D_SHELL_LN=8: shell history line count (how tall the shell is in lines)
    • D_SHELL_FS=16: font size for both the shell and on-screen flashed messages.
  • Debug Colors and Hitboxes (default invisible=off):
    • DOODLE_DEBUG_ALL=false: turn on all debug colors and hitboxes to their default colors and settings.
    • DEBUG_CHUNK_COLOR=#FFFFFF: background color when caching a chunk to bitmap. Helps visualize where the chunks and caching are happening.
    • DEBUG_CANVAS_BORDER: draw a border color around every uix.Canvas widget. This effectively draws the bounds of every Doodad drawn on top of a level or inside a button and the bounds of the level space itself.
    • DEBUG_CANVAS_LABEL=false: draw a label in the corner of every Canvas with details about the Canvas.
  • Tuning constants (may not be available in production builds):
    • D_SCROLL_SPEED=8: Canvas scroll speed when using the keyboard arrows in the Editor Mode, in pixels per tick.
    • D_DOODAD_SIZE=100: Default size when creating a new Doodad.

Development booleans for unit tests (set to any non-empty value):

  • T_WALLPAPER_PNG for pkg/wallpaper to output PNG images.
