Oh uh. The Sprite 2 is the control rods. The Sprite 1 is the fuel rods.
I'm not planning on changing any animation frames based on the height of the control rods. It's an unimplemented feature. Basically it will be this: height of control rods > sprite 1 temp variable > animation frame of sprite 1. But it's wholly unimplemented.
I'm trying to guess how to get the control rods (sprite 2) to pull up, instead of down.
