Noah Petherbridge 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.		2022-04-10 12:40:25 -07:00

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.
