So I rewrote the codes and the turning right animation works fine, but the turning left animation won't even trigger. The sprite just freezes up when you're facing left. But if you press right while facing left, the turning right animation plays fine. I'm new to construct so I'm probably missing a ton of stuff, so if anyone has a c3p file of how to do this, it would save a lot of time and frustration. My new codes are as such:
On left arrow pressed and sprite is NOT mirrored, and Turning right is NOT playing, then set animation Turning left then set mirrored. The same codes for turning right with the mirror changed and the animation set to turning right. In another event, Is turning left animation is playing OR turning right is playing, then start ignoring player input. Then in another event, on turning right or turning left finished, stop ignoring player input and set animation idle. The set moving animation will only trigger if animation turning is not playing as well.
