I try to resolve a problem since many hours now and i don’t find how to resolve my problem.
When i spawn my bullet for each player, server or client when i stay pressing my left mouse the rotation and my location where spawn my bullets for my actual player doesn’t move when i move my player and look around.
Also, use Get Forward Vector instead of RotateVector. Keep in mind that unit vectors in UE4 are 1 cm, so you are only moving the spawn location forward 1 cm.
