object moves not synchronous

I want to do a multiplayer game and i have some issues with the object that moves in 2 player not synchronous. But why? thats the code

Nothing will ever truly sync in multiplayer. You can get close, but latency/loss, processing speed, framerate of the clients have an impact on this.

but how it´s possible that i see the difference of this object in two clients. it should be nearby on same position

First issue in your code is you aren’t limiting it to the autonomous proxy. What’s happening is The autonomous and the sim is moving the actor.

Autonomous Proxy : move Location + 2,000 Y
Simulated Proxy: move Location + 2,000 Y

Your multicast needs control logic.
MC: Is Locally Controlled (Branch) [true] → MOVE
