Is forced camera movement possible in TGE 1.4.2?

I was thinking about creating a game where the camera forces the player forward if he stops moving. This way the play has to keep moving along a certain path. And if the player goes to far ahead, the camera keeps him back. The player can also not leave the by exiting to the sides. So basically, the camera is following a certain path, and the player is restricted to that path, also. Is this possible? Is there a resource on it? I can't seem to find much.

EDIT: Without compiling could be helpful. If I have to, I guess I can use xCode to compile TGE.
