Originally Posted by SaraAki I tested both versions,from Krtola and Tote last edit.What I noticed is that knockback work every time when i stab player from my team,but when i stab enemy,knockback doesn't always happen.It actually only happens when i kill the enemy player with knife right click,but not always.Is it possible to adjust that the effect does not affect my teammates?And to affect enemy player every time when i stab him?
