How i list all the variables in my project?

Hi,

I'm trying to make a console, where a user would type command that would modify some things in the game. One of the things that i want to do is being able to modify any variables. But I can't find anything that would list the variables, not even the number of variables. Is there some way to automate this, or will i really need to make an event for each variables?

You would probably want to use a dictionary instead of individual variables in this case.
