Moving background elements at fixed speeds

You can move multiple background elements together, and they will all move at the same speed...

.spSpeed(40) .spSpeed(20) .spSpeed(3) .spSpeed(1) .spStop() .spStart() .spToggle() .spChangeDir('left') .spChangeDir('right')

 

Vertical Panning

.spChangeDir('up') .spChangeDir('down')

Moving background elements at relative speeds

.spRelSpeed(40) .spRelSpeed(20) .spRelSpeed(3)

 

Changing the speed of and stopping and starting sprites; changing sprite 'states'.

.fps(24) .fps(12) .fps(6) .fps(1) .spStop() .spStop(true) (returns to frame 1) .spStart() .spToggle() .spState(1) .spState(2)

 

To change a sprite's 'state', you need an image with multiple rows, where each row is a 'state' (1, 2, 3, etc.) and each row contains multiple frames, like the following image:
