I played a lot of Barotrauma, I play with my friends and when we play in the Barotrauma Extended, I spawn a an entity and when i type control ------ it says character ------ not found,

Can someone help?

Are you sure you've spelled the name correctly? You can also use tab to autocomplete the name, so you could try only entering "control" and hitting tab until you find the correct character.

Yeah... my mod only deals with xml external code files so Commands should work the same way they do in Vanilla.

If Its A Dedicated Server Do "setclientcharacter yourusername ; usernameyouwanttocontrol
