Cocos2d Collision Bug

After continuously debugging and trying to fix this problem I am still have absolutely no luck…Can anyone please help me with this? It’s driving me insane.. I am using cocos2d v2 for iOS and basically I made a simple collision detection check method: -(bool)collisionWithPoint:(CGPoint)center1 andRadius:(float)radius1 andPoint:(CGPoint)center2 andRadius:(float)radius2 { float a = center2.x - center1.x; float b = center2.y - center1.y; float c = radius1 + radius2; float distanceSquared = (a * a) + (b * b); if (distanceSquared < (c * c)) { return YES; } else { return NO; } } I also have an array keeping track of my enemies being added to the scene. I alloc in the init method: _enemyFish = [[NSMutableArray alloc]init]; Then I add my enemy to the array like this: [self addChild:yellowFish z:50]; [_enemyFish addObject:yellowFish]; I also remove it from the array like this: CCMoveTo *move = [CCMoveTo actionWithDuration:speed position:ccp([login to view URL], randY)]; CCCallBlockN *done = [CCCallBlockN actionWithBlock:^(CCNode *node){ [_enemyFish removeObject:node]; [node removeFromParentAndCleanup:YES];}]; [blueFish runAction:[CCSequence actions:move,done, nil]]; Then in my update method I check for collisions: -(void)update:(ccTime)dt { for (CCSprite *enemy in _enemyFish) { if ([self collisionWithPoint:[login to view URL] andRadius:[login to view URL] * .3 andPoint:[login to view URL] andRadius:[login to view URL] * .4]) { [self gameOver]; } } } However, my issue is that my player will randomly die (gameOver scene being called) without being anywhere near the enemy. This only happens randomly though which confuses me. I have debugged with multiple CCLog statements to determine that this is indeed the issue. Does anyone have any idea why I would randomly be “colliding” with nothing based off of my given code? I can provide other code if needed. Thank you!
