some problems with mouselook
Author
hello,
i am using the following code to implement the classical FPS-mouselook.
the problems i have are mainly windows-programming oriented.
1. when i get the cursor out of the window, then it screws up the rotation. if i try to keep the cursor inside the window by setting it to its previous location after each rotation, then i cant move at all, since the cursor position never changes.
2. how can i smooth out the movement a bit? i want a bit of a fading effect towards the final rotation.
