Following Camera

How do I code the camera to follow a certain model from a set distance, but also be able to rotate as the model rotates?

Thankfully, this is an easy problem to fix. Click the "properties" tab for the camera, and click "vehicle" and set it to that object. You can also drag and drop it into your code to switch the object's vehicle during your program. Experiment around with this!

Good advice JRR-
Another option, is to position the camera to known locations that you will need tor the animation, drop a Dummy on the Camera, and set the Camera's point-of-view to the Dummy when you need it.
You might also want to experiment with telling the Camera to turn as seen by the object it's currently looking at.

Ha, That's a really funny animation! Do you still have the a2w file for it? It looks like it was supposed to be a game or something... Anyway, yes, that's another way you can do it... changing the vehicle is easier, though!

Yeah, It's a treasure Hunt- I used all the discussed techniques in that scene. Look for the Multiple Camera Position and Vehicle changes. He Can't get to Act 2 until He gets the key

I went into myFirstMethod, and made a code that says while true is true, the camera should be a set vehicle to the model, but when I run the program, it doesn't move anywhere.

Well, maybe true is false

The model needs to move, too. It works just fine for me. Try initially having the vehicle be the model you are going to move. I added an example. Tell if this works! If it doesn't please try attaching your Alice program to a post and we can review it.

Are you using Alice 3.1? This file you sent me can't be read from my Alice 3.1 program, and I don't know how to move it into the Alice saved projects folder(assuming there is one). Also, I don't know how to set the camera to a vehicle, because I can't select the camera, and I can't change the model into a vehicle, because I can only change it between green and brown.

No I have Alice 2. Alice 3 doesn't run on my machine. Sorry, but I don't think I can be much help on Alice 3 worlds

Do you know any place I might look to get help, then? Or should I download Alice 2? It seems Alice 2 is a bit better than Alice 3.
