Unable to send LocalPlayer from Client to Server?

justalemon · 2018-11-15T01:46:24.011Z

I have tried to do this for the last hour or so. Running the following from the client:

TriggerServerEvent("exampleEvent", LocalPlayer);

Raises the following exception:

Is possible to send the LocalPlayer from the client to the server without random tricks?

Please note that LocalPlayer is not null, I can use properties like LocalPlayer.IsAiming and functions like LocalPlayer.SetSuperJumpThisFrame();

Why are you trying to send the whole LocalPlayer object to the server?

LocalPlayer is just a CitizenFX.Core.Player object, and I need it to identify the origin of “exampleEvent”.

I don’t know how it works on c# exactly, but normaly you can’t handle a player on server side, just the network id.

I’m not sure at 100%

justalemon:

What? No, you don’t. That’s what FromSource is for, and in the worst case, you send the player’s server ID, not some whole object.
