Collision with CCSprite
- by Coder404
I'm making an iOS app based off the code from here
In the .m file of the tutorial is this:
-(void)update:(ccTime)dt {
NSMutableArray *projectilesToDelete = [[NSMutableArray alloc] init];
for (CCSprite *projectile in _projectiles) {
CGRect projectileRect = CGRectMake(
projectile.position.x - (projectile.contentSize.width/2),
projectile.position.y - (projectile.contentSize.height/2),
projectile.contentSize.width,
projectile.contentSize.height);
NSMutableArray *targetsToDelete = [[NSMutableArray alloc] init];
for (CCSprite *target in _targets) {
CGRect targetRect = CGRectMake(
target.position.x - (target.contentSize.width/2),
target.position.y - (target.contentSize.height/2),
target.contentSize.width,
target.contentSize.height);
if (CGRectIntersectsRect(projectileRect, targetRect)) {
[targetsToDelete addObject:target];
}
}
for (CCSprite *target in targetsToDelete) {
[_targets removeObject:target];
[self removeChild:target cleanup:YES];
}
if (targetsToDelete.count > 0) {
[projectilesToDelete addObject:projectile];
}
[targetsToDelete release];
}
for (CCSprite *projectile in projectilesToDelete) {
[_projectiles removeObject:projectile];
[self removeChild:projectile cleanup:YES];
}
[projectilesToDelete release];
}
I am trying to take away the projectiles and have the app know when the CCSprite "Player" and the targets collide. Could someone help me with this?
Thanks
