nooo I dont believe it!!!!! :) I come from Flash and Core Animation is like Fuse Framework of Moses. Is a way to have some sort of "collision" method of one or more layers?

I placed this code: -(void)mouseDown:(NSEvent *)theEvent { // [...snip...] [rootLayer addSublayer:textLayer]; } what ive noticed is when I click,the text appear with a fadein. Any reason of this behaviour?Modifying most layer properties as well as adding/removing sublayers generates implicit animations. You can temporarily disable animations by wrapping the relevant code in a CATransaction:- (void)mouseDown:(NSEvent *)theEvent { [CATransaction begin];[CATransaction setValue:(id)kCFBooleanTrue forKey:kCATransactionDisableActions];// [...snip...] [rootLayer addSublayer:textLayer]; [CATransaction commit]; } /brian
