You were telling Construct to set your running/standing animation without any regard for whether the throwing animation was playing. So it would start the throw, but then the very next tick it would set back to standing. You have to be careful about the order of your events, and make sure that you're not canceling your own events out accidentally.
I added a "NOT Animation "kakashi throwing" is playing" condition, and made your running and standing events into sub-events under it.
I also set your throwing animation to not loop, and added the "Set to frame 1" and "Play" actions to the On Key event. It works fine now.http://willhostforfood.com/files3/7264753/Unnamed.cap
THANKS!! At least now I understand why it was twitching lol. By the way, your platform tutorial helped me out a lot. I'll be back with more problems in the future lol.
