	// contains filtered or unexported fields
}

A Sheet is a collection of sprites

func NewSheet

func NewSheet(r *sdl.Renderer, imgFile string) *Sheet

func (*Sheet) Add

func (s *Sheet) Add(r *sdl.Rect) (idx int)

Add adds specific region as a referenceable area and returns the reference ID

func (*Sheet) Copy

func (s *Sheet) Copy(r *sdl.Renderer, dest *sdl.Rect, idx int, scale int32) error

Copy copies the given reference index from the sprite sheet onto the renderer

type Sprite

type Sprite struct {
	Position sdl.Rect
	// contains filtered or unexported fields
}

A Sprite is an object represented by a texture and a position

func NewSprite
