Okay...FYI, I only use 'sprite_index' 'image_index' 'if' for Amy's animation. it's just multi-layer of simple codes...hope this will help.

I was using a switch for my animations though (to make per-state actions as well as transitions into attacks easier.) So it's not as simple as that.

You can just use 'sprite_index' to change sprite set. it doesn't change 'image_index'. so your animation will perfectly sync.

in SSS. the code works like this:

in Step event: check Amy is on floor or in air. change sprite.
in Key events: set Amy's status, moving, firing, aiming...

Well it was more of a series of questions. Like for example currently I'm struggling with animation transitions (shooting while in the air then landing while still shooting.) Since all my animations are 3 frames, I wanted to try and sync them. (if I transition while in frame 1 of my air shooting animation, when I land I start on frame 1) However, I'm having difficulty getting all the logic down, and I wasn't sure where to start on that.

Go on. what do you want to know?

Hey, I was wanting someone knowledgeable to ask questions reguarding gamemaker, and I was hoping I could ask you a few questions here and there about it if that is alright with you.
