Zoom Demo

What does it do?

It demonstrates how one can zoom in/out, by using the mouse wheel.

For doing so, it created a green background. This way, you'll notice the zooming.

What are important aspects of the code?

These lines are key in this demo:

// Scroll is called whenever the mouse wheel scrolls
func (game *Game) Scroll(amount float32) {
	// Adding this line, allows for zooming on scrolling the mouse wheel
	engi.Mailbox.Dispatch(engi.CameraMessage{Axis: engi.ZAxis, Value: amount * zoomSpeed, Incremental: true})
}
