OMG..
I can't believe it's this simple. I figured it out...I'm so happy, It's been 3days 18 hours a day trying to figure this out.
player 1
1. get position of spawn transformer. "Vector3"
2. Convert Vector3 to String "String"
3. send rpc with String Data "String"
Player 2
1 Get Event Info - String data " String"
2. Convert String To Vector3 " Vector3"
3 . Set position bullet spawn point with Converted String "Vector3"
I'm sorry for my bad grammer, I'm just very happy at the moment.
