now my function looks like this:
Code:

---

void erdbeere()
{
	NewtonBody *body;
	c_updatehull(me,0);
	set(my,POLYGON|FLAG2);
	while(my.z>-50)
	{
		wait(1);
	}
	NewtonDestroyBody(nworld, body);
//	ent_remove(me);
}

---

this however leads to an engine crash with no further explanation

btw, how do i setup such a Callback? Never did this before
