How do I create a character swap mechanic?

I'm currently trying to make a mechanic where you would swap between two characters, having control of one character and with the press of a button you would swap to the other character, i've tried having it as a boolean instance variable for the two characters so when the button would be pressed it the player would have control of the other character but it doesn't seem to work. I was wondering if i could get some help with what could be done to get it working.

I would have to guess that it's not working because events run top to bottom, it might be setting a boolean true and then false again in the same tick. If your conditions are set up like if false then set to true, if true then set to false. You could press a key, then pass the current variable through a function to check it.

Doesn't seem to work although the second character did drop to the floor as previously it was just frozen in midair.

Can't see your game so no idea what that means. Post a screenshot of the events for the character switching.

Unfortunately that's doing the same thing but has moved to a function so will produce the same error. You should move the selected player to a global variable, something like this :

Ok it finally works, thanks for the help
