hey Galandil! Thx for the update on your game!
Is it that you don't know how to use variables in your events (cause I think that would go in the Support/Help forum,)
or are you wondering how to use variables in a script you created,
or are you wanting to tinker with the variables in a script you are using,
or do you want to learn how to use variables in scripts?
(for the first one, check the tutorial section,
for the last one, check the "Learning Scripting" post in this section,
for the others, you'll need others
