History

Noah Petherbridge 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

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.
