Functions

func DrawCanvas

func DrawCanvas(win *pixelgl.Window, canvas *pixelgl.Canvas)

DrawCanvas draws a canvas to the window, properly scaling and moving the canvas to fit within the window.

The aspect ratio of the canvas is maintained when scaled.

func Render

func Render(win *pixelgl.Window)

Render calls the render method of the currently active scene if it exists.

func TransitionTo

func TransitionTo(o Scene)

TransitionTo changes the currently active scene, destroying the previous scene if necessary.
