I have a problem with "on collision" event
it doesn't work sometimes
I have an object that moves with "Custom Movement" behavior (for example x) and another object that moves with "Drag and Drop" behavior (y)
I set an event that when object x is on collision with object y, object x destroys itself
but sometimes it doesn't work, specially in mobile devices (I used cocoonjs, iPod 4G)
please tell me how to fix this.
