I was having serious issues with hooking the fsr up to processing. This was meant to be a “are you ready?!” kind of sensor. So, that the moment the user holds/presses the sensor the game begins (just because physical sensors are more fun than regular keys). But, I sort of failed because the game was just laggy without fsr reading but flowed nicely with fsr reading.
