Quan el flag està desactivat, el látigo no fa dany a altres jugadors (l'owner ja quedava exclòs per la guarda existent). Default true: manté el comportament actual. Sense canvis als tests del whip — friendly fire ja no es cobreix allà perquè els stubs de Player no porten estat real (vegeu el comentari del top de test_whip_attack.cpp).
