thanks alot vee41 i will work on it and will tell you the results :)
edit #1 : yeah that kinda worked like i described but there is a small issue that it doesnt hover upwards than falls if i could draw a waypoint for that. I would be happy.
I tried to give physics effect to the diamond but it didnt give the result that i wish i had :D diamond was floating around because of both bullet and physics behaviour imho :)
