Shoot in 3rd person (multiplayer)

Hello!

Since a long time ive got a huge problem.
I am working on a 3rd person game. The problem is I can not get “shooting at others” to work correctly.

I have now tried many different things.

Now here is the character in an empty level in case u want to test and see it. (7mb)

This is from a version where I use the world location and rotation from the camera, wich brings the following bugs.

Someone helped me to solve this issue, but in a way that is rather questionable for a multiplayer, and I cant really get the replication of this to work since the server seem to know the position.

Please help!
