I'm making a physics game and I need to have rotated images for each of the objects in the game. Any way to make a script in gimp that rotates the images 1 degree and then saves them?

As Telastyn mentioned, for every one image in your game (of which you'll probably have over a hundred), you'd have to create 360 copies of it, each slightly rotated. That's alot of wasted memory.
Pick an API that can just draw a single image rotated in whatever way it wants. Most hardware accelerated 2D or 3D APIs can do this.
If your API of choice can't do that, then for games you really only need to do one image per every 15 degrees or rotation, or perhaps even less (every 22.5 degrees or something).
Every 1 degree = 360 images for every one image you want to rotate.
15 degrees = 24 images for every one image you want to rotate.
22.5 degrees = 16 images
45 degrees = 8 images
