Adding and subtracting variables with scripts

[voxet]

i put this in as a test (lost level being the name of my var with 2 as its id) and it is not working
and advice on where i can learn more about using variables in scripts becuase i wanna go on to do some more advanced operations

$gameVariables.value just gives you the actual value of that variable. To set it to a particular value, you need to use $gameVariables.setValue. So, for example, $gameVariables.setValue(2, 10) will set variable 2 to the value of 10.

To add to and subtract from the variable, you could use

$gameVariables.setValue(2, $gameVariables.value(3) - 10)

which will set variable 2 = variable 3 - 10.

Note that these operations can all be done using a couple of event commands (without scripting), unless you have something different in mind.
