I have an idea!  
Make a variable of gas collected! So when you collect 1 gas you change the GasCollected variable by 1 (or make it so it is more) Then when you get to a generator you set the GasInGenerator to GasCollected and then set GasCollected to 0!  
Hope this helps!

I had that idea too! Instead of ‘GasCollected’ I had ‘AddGas’. But how do I change a variable value?

`AddGas += 1`
