Dynamic (Overly Complicated) Lock On System

Please suggest changes or tell me of bugs. I'm aware of one where the decal doesn't remove itself. I'm not that bothered by it, since I'm going to swap it with a widget at some point.

You can use it for whatever if you want to. Everything is explained with a comment, maybe not the most in depth explanation, but you should be able to understand.

This is my 4th iteration on this system, it's getting close to what I want. 

Known Problems:

Sometimes the lock on snaps, could be solved using a timeline.

Lock On Decal doesn't always destroy itself, will replace with widget at some point.

The camera angles feel odd

Sometimes if the ease function is set to ease out or in/out it crashes.
