...well then, let me take a look in the manual...


phent_addforceglobal (ENTITY* entity, VECTOR* vForce, VECTOR* vPos );


...I'm not entirely sure of this, but I think this is what you need. Of course set ENTITY to the target physics ent.

Set FORCE to the bullet direction, and it's magnitude to the force. To do the latter, use vec_normalize(vector, 1000); 1000 being a random guess for force

and vPOS to the point where it hit the entity.
