Issue

Client execute a server function failed:

LogNet: Warning: UIpNetDriver::ProcesRemoteFunction: No owning connection for actor TopDownCharacter_C_0. Function ServerMoveToDest will not be processed.

Cause:
Because the Actor which invoking server function on client doesn’t have Connection.

Solution:
How to let object have Connection?

  • For Characters, possess it by PlayerController on server after spawning this Actor on server.
  • For Actors, Set a Owner which has Connection for it.
Notices for Dedicated Server
  • Properties which be flagged as Replicated can only be modified on Server, Modifing on client doesn’t take effect.
  • Clients can only communicate with Server, Clients can’t communicate with each other client directly.
  • If Client want to invoke a Server Function, it must be spawned on Server and has the Connection, otherwise invoking would be failed.
