Defining your own sprites and animations isn't as scary as it seems at first. Take a look at BUB for some reasonably-clear examples: 83DXN3L4 Read up on the SPDEF and SPANIM commands; both have a variety of ways to define and animate sprites. My BUB game uses a DATA block to define them and inline SPANIM commands using "I" to determine which frame is shown for how long etc.
