could anyone explain to me what CGPointMake does please? image.position = CGPointMake(80,200); id go = [MoveTo actionWithDuration:2 position:CGPointMake(190,460)]; for example this syntax above. I am not quite sure It's an inline function that populates a CGPoint struct with the values you pass in.
