Reverse a Command
« on: September 01, 2016, 06:19:24 PM »
Hi, I've got a question. How do you, if at all possible, reverse a function or command? Such as have an action that reverses a command. I've tried using setOpposite and unless I'm doing it wrong it does nothing.

I've searched the forums and haven't found anything on this.

Thanks.

Take a look at an example in the ULX codebase: ulx gimp
This should give you the basic syntax for setting a command's opposite. Basically, you need a hidden Boolean argument, and you need to check if you need to reverse the logic in your command's function.

edit: It would be nice, though, if you provided us a sample of your code and explained your use case better (see below).

I wonder if he means like a "ULX Undo" where it undoes the last ULX command executed. if so that would be cool if someone could get running smoothly.
