Just started attempting in a Game Jam and went to add a sword to the player, I did not even get to the adding the sword doing damage when I relised that the sword was causing the player controls to be all over the place and the play to walk so fast as if they are clipping. Any ideas?
The character is probably clipping with the sword. Try attaching just the sword mesh in the socket, not a whole actor. I would probably go as far as adding a mesh component in the character itself (as part of its composition) and just hiding/changing its mesh.
Good luck in the jam
