Question

im trying to make a multiplayer game but when i create a server and join the host controls everything. İ know that it is an issue with setting authority but i dont know how to fix it for my game specifically (i tried to fix it but failed)

When you connect input devices to your computer they show up in Input Map settings. You basically map input devices for local. And, creating a synchronizer node. Two, shots.

? i mean i do have a multiplayersynchronizer node set up and also i tested the inputs in singleplayer… they function.
