PlatformState
A state record provided by platform on each frame.
{ frameCount : U64, keys : InternalKeyboard.Keys, mouse : { position : Vector2, buttons : Mouse.Buttons, wheel : F32, }, timestamp : Time.Time, network : { peers : { connected : List Network.UUID, disconnected : List Network.UUID, }, messages : List { id : Network.UUID, bytes : List U8, }, }, }

KeyboardKey
Represents a keyboard key, like KeyA or KeyEnter.
Rectangle
Represents a rectangle.
{ x : F32, y : F32, width : F32, height : F32 }
Vector2
Represents a 2D vector.
{ x : F32, y : F32 }
Color
Represents a color using a tag union.
# a generic rgba color RGBA { r : U8, g : U8, b : U8, a : U8 } # predefined colors White Black Red Green Blue ... etc
Texture
A static image loaded into GPU memory, typically from a file. Once loaded, it can be used
multiple times for efficient rendering. Cannot be modified after creation - for dynamic
textures that can be drawn to, see RenderTexture instead.
RenderTexture
A special texture that can be used as a render target. Allows drawing operations to be performed to it (like a canvas), making it useful for effects, buffering, or off-screen rendering. The result can then be used like a regular texture.
Sound
A loaded sound resource, used to play audio.
Camera
A camera used to render a 2D perspective of the world.
