Game System

This defines traits for a 2D game framework and gives an implementation based on rust-sdl2.

Core

• memory management (textures / audio)
  • specify resource by file path and don't worry about managing anything!
• window creation (single window support only)
• input event handling
  • mouse
  • keyboard
  • window
• textures
  • from image file
  • from rendered font
    • pt size
    • wrap width
    • color
  • from software rendered (raw pixel access)
  • copying to screen - src + dst + rotation
  • clipping rectangle (aka scissor)
• audio
  • sounds
    • direction and volume
    • looping support - adjust while playing
  • music
  • fade in / out

UI

• only uses the core interface
• immediate mode
• optional super low idle CPU usage (only update on events received)
• widgets
  • tree hierarchy
  • tiled background
  • tiled border
  • button
  • checkbox
  • debug (test sizing)
  • multi line label
  • single line label
  • strut (force spacing)
  • image display widget
• layout
  • vertical / horizontal
  • scroller
• sizing information
  • min
  • max
  • preferred portion (e.g. 50%)
  • preferred aspect ratio
  • displacement (on min or max length failure. e.g. "right align text")
