Mouse moving left or right (relatively speaking)

SDL Development
1

I am learning OpenGL and picked SDL for my event/sound etc library. I’m
really impressed with it. I am having a problem though. I can’t seem
to figure out exactly what I need to do to determine if I have moved the
mouse left or right relative to the screen. I made a very simple 3D
world (floor and sky) and can move about with the keyboard just fine.
But I would like to control the view with my mouse. Similar to all
those oh so familiar 3D shooter games.

So basically I need to remove my events for the LEFT and RIGHT key
events and call methods accordingly when the mouse is moving left or
right. Any help would be great.

Thanks.

Using the SDL_MouseMotionEvent (
http://sdldoc.csn.ul.ie/sdlmousemotionevent.php ) you can get
the current, and relative coordinates of the mouse.

This will give you 2d movements of the mouse, but you want 3d. Check
out this tutorial from gametutorials on how to do this:

It shows you how to use a combination of keyboard + mouse to have quake
like movements in a game.
