func (a *Application) KeyState() *window.KeyState

KeyState returns the application's KeyState.

func (*Application) Renderer

func (a *Application) Renderer() *renderer.Renderer

Renderer returns the application's renderer.

func (*Application) Run

func (a *Application) Run(update func(rend *renderer.Renderer, deltaTime time.Duration))

Run starts the update loop. It calls the user-provided update function every frame.

func (*Application) RunTime

func (a *Application) RunTime() time.Duration

RunTime returns the elapsed duration since the call to Run().
