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.

Attach the component to a slot and provide a <code>Target</code> or <code>TargetPoint</code> 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.

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.
