alice-teacher Camera issues with 3.1

[Melia, James E.]

Nope- the camera can’t move on it’s own and remain centered on the object…. The camera just moves to the right as the object goes out of view…

This is unfortunate, as it is a basic skill I teach at the beginning to get camera and object movement experimentation among the students, and it won’t work.

I hope you find a solution. I may go back and just load 2.4.3 back onto the machines….

Jim,
You are right, this code in Alice 3 does not function the same way as it does in Alice 2, and right now I do not have a good explanation for it. Here is a work around that comes close to replicating the Alice 2 behavior. You may play with the duration and loop control values to see if you get better performance.

Do Together
   camera move right 10 meters duration 4 seconds Begin and End Abruptly
   Count 4
       Camera pointAt (obj) duhration 1 Second Begin and End Abruptly

Let me know if you have any questions...

and the camera would follow the object. It does not do this in 3.1.

How do I make the camera stationary but focused on a moving object?
