when i change animation by moving forward or turning left/right.. sometimes the animation flickers and shakes... not very attractive..

is there a reason why its doing this? advice on how i would set the animations more smooth?

thanks!

Are you sure your animations are lining up?

It looks like your 'fire exhaust spaceship' and 'idle spaceship' animations might be skewed a little bit.

they should rest on top of eachother exactly

Yeah its the exact same image only painted the crappy flames to test it out.. any other ideas man?

bump

are the collision boxes the same?

nah, that seemed to fix it tho thanks!
