Is there any easy way to disable the camera movement? When you create the model, if you move the mouse, the model rotates around the camera. How can you disable that? :?
The camera is rotated by the FirstPersonHandler created in SimpleGame. You can replace it by calling
input = new InputHandler();
At the beginning of your simpleInitGame method. Note that this also replaces other input stuff initialized in SimpleGame.
Here's my class which does all the input handling. Maybe you can reuse parts of it.
