Running a SCNNode animation just once on Scene Kit

Question

I'm trying to run an animation from a .dae file (3D model file) just once, this is my code:

SCNNode *object = (SCNNode*)[self getMyPlayerObject];
NSString *key = @"hit";
CAAnimation *animation = [_animations[key] copy];
[animation setSpeed:1];
[animation setTimeOffset:0];
[object addAnimation:animation forKey:key];

I've tried using animation.removedOnCompletion = YES; but is not working, I've tried setting a delegate and tried to detect it with the animationDidStop:finished: method, but it doesn't even get called, there's something weird when using CAAnimations on SCNNodesfrom DAE animations.

Is there any way of doing it?

Thanks in advance.

Is the animation repeating? Check `repeatCount` and `repeatDuration`. — David Rönnqvist, Jan 07 '15 at 08:34
@DavidRönnqvist I set repeatCount to 1 and it did it just once! Thank you. Can you set it as an answer? Or should I do it? — c4b4d4, Jan 08 '15 at 06:14

Your animation is likely configured to be repeating. Check the repeatCount property to see if it's larger than 1. Setting it to 1 will repeat the animation once, but you can also set it to 0 to ignore it. if that's not it, you can look at the repeatDuration property and set it to 0 (to ignore it) if it's not already 0.
