I havent tested it but instead of looping over the touches try just getting one of them using the anyObject method of NSSet:

replace:

for (UITouch *touch in touches) {

            CGPoint position = [touch locationInNode:self];
            [self shootProjectileTowardsPosition:position];

        }

with

UITouch *touch = [touches anyObject];
 CGPoint position = [touch locationInNode:self];
[self shootProjectileTowardsPosition:position];

Thanks for the response, I tried it without success.

Rodrigo Post your code that is not working because Stone's suggestion should work.
