Well they can't be in a layout under the character, so I guess you mean layer..
If they are in a layer under the character they can never show in front, so this must be untrue..
Are you spawning your objects in the right layer?
Is the character moved to a different layer in the events?
Would it help to have an on collision event - move character to top?
I told my dentist I had trouble with my teeth and asked her to fix it without looking in my mouth..
