alice-teacher Camera issues with 3.1

[Eric Brown]

Understood.  I definitely understand the difference between the vehicle option I outlined and the panning to follow that you desire. I was just offering up a different option for a dynamic camera movement that could follow an object that you may already be using until we could implement the solution you desire.   As Don said we will definitely look into why the point at method isn't functioning during a do together in Alice 3 and so is not achieving what you want.  

Thank you for bringing this to our attention.  

Sincerely,

Eric

For instance "Camera move right 10" do together "point at chair" and the camera will move right 10 but not continue pointing at the chair, so the chair goes out of view. These were basic scenarios we did with camera movement in Alice 2.4, but it doesn't work the same or just doesn't work in 3.1. If that is the case, I will go back to 2.43...
