Inverse Kinematics<br>
<br>
Here's what I did:<br>
- Because of a miscommunication about deadlines I was unable to complete the IK part of my proposal.  I did however get a good start:<br>
- I created a class tgIKObstacle which extended tgCharacter.  This represents all three points connected by two lines (like the midterm problem).  I treated the position as the part of the object that would move and the other points would be calulated from.  tgIKObstacle had a method called updateIK which would be called every frame and I only got as far as calculating the location of the middle point from the position point.  I was able to make this work properly, but I am certain there are only minor mathematical errors preventing this from working.<br>
- I planned on having a sprite for the IK chain and it would have fit easilly into the framework of the my sprite animation.  The class tgIKObstacleRenderer takes care of actually drawing a representation.  There isn't much to show right now so I have the IK stuff turned off.<br>
- You can download the code in the Final Submission.<br>
