Hi!
For someone coming from unet I dont quite understant why there are 2 roles for each instance; Role and RemoteRole. I do understand that they are swappable wether we are the server or client running instance; my role is always Role and the other’s is RemoteRole, what I dont understand is WHY do we care about the other’s role? I mean, its not like we could run code for them, right?
Quote ue4 doc:
Role/RemoteRole Reversal
Role and RemoteRole could be reversed
depending on who is inspecting these
values. For example, if on the server
you have this configuration:
Role == ROLE_Authority RemoteRole == ROLE_SimulatedProxyThen the client would see it as this:
Role == ROLE_SimulatedProxy RemoteRole == ROLE_Authority
What I further dont understand is why the Roles swap wether we are running in the Editor or a Build/Standalone.
For instance, in Build/Standalone play i’ve got some code that doesnt execute if I test (Role== Role_AutonomousProxy) but does if it is (RemoteRole== Role_AutoProx). Inversely, the same code doesnt run in Editor if I have (RemoteRole== Role_AutonomousProxy) but does if it is (Role== Role_AutoProx). Notice that Role & RemoteRole are swapped.
For my code to run as expected in both Editor and Build I must test for (GetRemoteRole() == ROLE_AutonomousProxy || Role == ROLE_AutonomousProxy), which to me doesn’t make any sense? Why have 2 different means of verifying the same thing wether it is build or editor?
For context: this code is run in the Player’s owned pawn, spawned by Server with the Player’s PlayerController as Owner. This condition decides wether or not I enable a CombatSystem module for the Player to run locally. In which case only the controlling player needs it and the Server/Clients dont. Also, I dont it does much, but “Run Dedicated Server” option is checked.
I would greatly appreciate any clarification on this, thanks!
