Look at is a component that is used to make one slot point to look at another slot via a SwingTwist interpolation. Swing Twist is a concept that is too complicated to explain on this wiki, but essentially constrains the rotation on two axies when rotating to a point, locking it within a range. kind of like a turret.

Usage
Attach the component to a slot and provide a Target or TargetPoint to make it look at or point at a position. It is recommended to put a slot under this component's slot to apply offsets to the rotation.
Examples
This can be used to make a piston base and rod look at each other to stay connected when the piston moves. this can also be used to make a tracking system.
