alice-teacher Camera issues with 3.1

[Eric Brown]

You could in code or in the scene editor "set camera vehicle to object”.  If in code just do it before the animation instructions.  The camera will then follow at the same view that it has at that point.  

If needed you could use "camera point at object” before setting the vehicle to have the camera orient to the object first if it isn’t already centered.

If you desire it to not follow the object after that point then set the vehicle back to “this" after that.

Sincerely,

Eric
