Run in debug mode and place a breakpoint as it enters the gamevariables method.
Check every object has been initialised before being used.

If this is a regularly called method then it might be better to first run it and allow it to crash, thus letting you identify the line where it throws the exception.

Whatever you do, any decent Java IDE will support easy debugging tasks such as this.

You get a null pointer exception when you are trying to use a variable/object when it has not been assigned/initialized.

From your exception the problem is in the gamevariables method, start by looking there.
