We know that non-simulated functions don't run on clients. But when we're in a simulated function, how do we tell the server and the client apart? For that matter, how do we know we're running the game in a network environment at all? There are a few variables we can use to help us out. The first, and most important, are Role and RemoteRole.
These two variables are declared in Actor as an enum and tell the game how the server and client should treat this actor. Let's take a look at the list:
enum ENetRole
{
ROLE_None, // No role at all.
ROLE_SimulatedProxy, // Locally simulated proxy of this actor.
ROLE_AutonomousProxy, // Locally autonomous proxy of this actor.
ROLE_Authority, // Authoritative control over the actor.
};
var ENetRole RemoteRole, Role;By default, Role will always be ROLE_Authority
on the server. This makes sense, since the server needs to have the last word on the state of all actors in the game. While...
