[C#] [System.Reflection.TargetInvocationException] How to use the methods that return dynamics?

Sander0542 · 2021-06-25T15:58:06.523Z

When I am tring to loop through player using the GetActivePlayers method I get an exception. I run this code in the construct of my Client script, but when I use it in the tick or some other method it always fails.

Code:

            List<object> players = GetActivePlayers();
            foreach (var player in players)
            {
                Debug.WriteLine(player.ToString());
            }

Exception:

GetActivePlayers returns a list of ints(player sources). Not player objects
You can try to cast them to a player like this Player player = new Player(source). However dont know if this works on the client side.

You can also access all the players with the Players property accessable in the class that inherited the basescript.

You can also cast it to a player using that playerlist like ```Player player = new PlayerList[Source];
