Using give item command as a timer

 

man thank you it really helped me, but one question, if i want all players to have the permission, can i just delete the

Code:

void OnServerInitialized()
        {
            permission.RegisterPermission(Perm, this); //Register the permission when the server initializes
        }

and

Code:

void cmdTestCommand(BasePlayer player, string cmd)
        {
            if (permission.UserHasPermission(player.UserIDString, Perm)) //Check if the player has the permission "Perm"
            {}
        }

 

Yes, or you grant your default group the permission.
