About variables, if anyone else is confused:
First of all, normal variables and idol variables are different.
Idols either have a variable, or not. You set them like "Girl1 -> Variable -> nice_variable", and remove "Girl1 -> Remove Variable -> nice_variable".
Then, to check if an idol has a variable "Variable -> nice_variable". If you need any idol without the variable, do "Variable -> !nice_variable".
================
To set a normal variable, you do "Meta -> Set Variable -> nice_variable = true". (you can use any word or number with no spaces, not just true)
Then, to check it you do "Meta -> Variable -> nice_variable == true".
Variables can also have numeric values, for example "Meta -> Set Variable -> nice_variable = 5"
Then, you can do "Meta -> Variable Math -> nice_variable + 1" (only + and - work)
And then, to check the value "Meta -> Variable -> nice_variable > 5" (you can use ==, !=, > and <)
