Functions

func FromColor

func FromColor(c uint32) (uint32, uint32, uint32, uint32)

FromColor used to decompress a color up to 4 uint32.

func ToColor

func ToColor(r, g, b, a uint32) uint32

ToColor used to compress a color down to a uint32.

Types

type Camera

type Camera struct {
	X, Y, Width, Height float32
}

Camera type used to hold the position of the camera.

func (*Camera) Activate

func (c *Camera) Activate()

Activate activates the camera on the current shader.

type Renderer

type Renderer interface {
	Begin()
	DrawRectangle(x, y, w, h float32, color uint32)
	Submit(ra munfall.Renderable)
	Flush()
	End()
}

Renderer interface used to talk to renderers.

func CreateRenderer2D

func CreateRenderer2D(vertexBufferSize, indexBufferSize int) Renderer

CreateRenderer2D used to create a renderer2d object correctly.

type RendersTraits

type RendersTraits interface {
	Render()
}

RendersTraits defines a collection of objects that can be used in conjunction with a world object to render traits.

func CreateRendersTraits2D

func CreateRendersTraits2D(w munfall.World) RendersTraits

CreateRendersTraits2D creates a 2D implementation of RendersTraits.
