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.
