Moving the Camera with the Avatar

The easiest way to keep the avatar on-screen is to move the camera wherever the avatar moves. If the camera is always pointed at the avatar, then the avatar can’t leave the screen!

First let’s find the line that says scene.add(camera) and delete it. Then, below the line where the avatar is added to the scene—and above the makeTreeAt function, let’s add the camera to the avatar:

​var​ leftFoot = ​new​ THREE.Mesh(foot, cover);
leftFoot.position.​set​(75, -125, 0);
avatar.add(leftFoot);

avatar.add(camera); ...
