Outputs a 0-1 value based on the speed on a single direction on a single axis. Read from the var.
Please note that due to the way it functions, it will provide a small amount of drag to anything it is attached to- If your machine is sensitive to that, be mindful of where it is placed in regard to your center of mass/center of acceleration.
In addition, due to the physics of the game, the slider may occasionally read a negative value. Be sure to account for this in any circuits.
Be sure the attached object has weight as well, otherwise weird physics will occur.
