put that thinks into a function;
Code:
 
        ph_setgravity(temp); // set gravity...crashes if i do this in main :/	
        phent_settype(my, PH_RIGID, PH_BOX);	
        phent_setmass(my, 2.0, PH_POLY);	
        phent_setfriction(my, 80); //play with this	
        phent_setelasticity(my, 1, 25); //play with this 	
        phent_setdamping(me,20,40); //play with this	
        wait(-3); // let gravity kick in...works on manual entities, but not ent_created for some reason	
        phent_enable(my,0); /// disable physics on this entity until      apply_physics is triggered


Everything is possible, just Do it!
