Change image animation while flying around with touch controls

Rogue Anvil

Am trying to get a little space shooter running. I'd like to change the animations rolling sideways when moving the finger left and right on the screen. Right now I am just moving the spaceship sprite around using constrain x and y:

I have a notion that one could simply try a rule saying something like if touch 1 x is > 1 (or < -1 if right) do changeimage, but it is not working... any ideas?

There are probably better ways to do this but here's what I came up with. The self.previousX attribute is type real. I start with an image of a rocket facing up. FYI, it's a Mac file but you should be able to open it on a PC. In case you can't, here are the rules that I added to the constrain behaviors you had:

Thanks, this works very well! ...am using animation instead of rotation, but your thinking solved my problem. Thank you

Hi @Rogue Anvil you can use the "Motion Linear Velocity" sign, and flip the image according to this

Correct me if I'm wrong but a constrained actor has no velocity.

Ups!, I not have idea if works with a constrained actor, he should check that!
