Are you asking why you would want to? Only you can answer that.
If it’s a typo and you are asking if there is a way to control two pawns with separate controllers the only thing that I can see that would stop it is if one of the controllers captures the input and the 2nd controller doesn’t see it. I’m not sure.
I think 1 controller is going to have to be the main one, and spawn the 2nd one, and then maybe pass the input to it as it’s handled.
Also, the player start is setup to drop only one character in, so you’ll need to handle spawning the 2nd character, probably off the Begin event of the 1st one makes the most sense, and set your references to it when you spawn.
