Ok I need to figure out how to do animations...
I know how I would do the offsets and numbers...
But I want to learn how it works...
I have 4 sprites of a stick that moves when you press the movement keys...
How would I tell my program that If I push a movement key, then the next animation for my sprite would show...

OH, all the animations are stored in Pic1!!!
I was storing them all independently!

No, you can't use the same pointer twice. You'll get ERR:duplicate.
Same for posting twice

Yes. But you can add optimization, like doing A*8+Pic1 (or even A*2*2*2+Pic1) instead of 8*A+Pic1. But nevermind: first of all, make the program work. And Yeong's method will work (I think)

I'm doing something like this in Essence...I optimized it after typing it so I'll comment it.
(original code here)

Assuming there's a different animation for each direction and there's four frames for each (and a sprite before that depicts standing still)
It might be possible to shave off some space by flipping the sprite horizontally instead of having different sprites, but you should get the idea of how to do it.

Edited for four sprite animation, also how to use for different # of frames
