CanUserLogin

OxideCarbonPlayer

Called to determine whether to user login.

Return true to allow the action and false to block it.

void CanUserLogin(string username, string userid, string ip)

Method changed — check — the game method differs from the one the hook is recorded for in Oxide. The hook is still called, but its place may have shifted — worth checking after an update.

Parameters

username: string
userid: string
ip: string

Return value

voidBehaviour is not described.

Example

private void CanUserLogin(string username, string userid, string ip)
{
    Puts("CanUserLogin");
}

Works in both Oxide and Carbon: Carbon loads Oxide plugins as is.

Where it is called

Oxide core (Oxide.Rust)

RustCore::IOnUserApprove(Connection connection)

Oxide core code — the hook is called from here

// …
    }
}

// Let covalence know
Covalence.PlayerManager.PlayerJoin(connection.userid, playerName);

// Call hooks for plugins
object loginSpecific = Interface.CallHook("CanClientLogin", connection);
object loginCovalence = Interface.CallHook("CanUserLogin", playerName, connectionId, connectionIp);
object canLogin = loginSpecific is null ? loginCovalence : loginSpecific;
if (canLogin is string || canLogin is bool loginBlocked && !loginBlocked)
{
    ConnectionAuth.Reject(connection, canLogin is string ? canLogin.ToString() : lang.GetMessage("ConnectionRejected", this, connectionId));
    return true;
}

// Call hooks for plugins
// …

Injection point

Rust.opj (Oxide)

void ConnectionAuth.OnNewConnection(Network.Connection)

Injected internal hook IOnUserApprove — this hook is called by its handler in the Oxide/Carbon core

Method changed — checkReturnBehavior: ExitWhenValidTypeArgumentBehavior: UseArgumentString (a0)Assembly-CSharp.dll

Where it is called (this branch's game code)

// …
		DebugEx.Log(connection.ToString() + " has auth level 2");
		connection.authLevel = 2u;
	}
	if (DeveloperList.Contains(connection.userid))
	{
		DebugEx.Log(connection.ToString() + " is a developer");
		connection.authLevel = 3u;
	}
	if (Interface.CallHook("IOnUserApprove", connection) != null)
	{
		return;
	}
	m_AuthConnection.Add(connection);
	StartCoroutine(AuthorisationRoutine(connection));
}
