Mouse movement

What’s the best method of working out which way the user is moving the mouse?
I don’t want to show the mouse cursor, I’m simply adding mouse control to a game, so the player can move their character via the mouse.

I have trouble, when using SDL_GetMouseState as soon as the mouse hits the edge of the screen.
I simply want a change in x value as positive, negative or 0.

I avoided such a problem by hiding the mouse cursor and using
SDL_MouseMotion event ( and its xrel and yrel signed field which seems to
return always a correct value, both of them associated with another var
storing X and Y mouse coordinate. )> ----- Original Message -----

The best way is to hide mouse cursor and grab input in initialization =
via call SDL_WM_GrabInput.
Then, at each game frame, poll mouse & keyboard via =
SDL_GetRelativeMouseState & SDL_GetKeyState.–
