Okey, that's nothing what I can download! *sigh*

Here's the relevant code section
Code:

---

	if (bDentCar!=0 && linSpeed>(CRASH_SPEED) ) 
	{
		////////////////////////////
		// find closest vertex and dent the car
		var i=0; var k=0; var tttt[3];
		
		var min_val=500; var min_i;
		
		while (i < ent_vertices (my))
		{ 
			vec_for_vertex(tttt,my,i);
			k=vec_dist(tttt,target.x);
			if(k<min_val) 
		        {min_val=k; min_i=i;}
			i+=1;
		}
		
		vec_for_mesh(temp,my,min_i);
		vec_scale(temp,0.9);
		vec_to_mesh(temp,my,min_i);
		ent_fixnormals(my,0);
	}
