Hi, I am fiddling around with SDL 1.2.13 and trying to control the camera look at with the mouse. Using the mouse to look around. If i use window's library i get no probs. But getting the mouse position with SDL_GetMouseState always returns 0 on both coordinates. I also have tried only using the window's GetCursosPos function and SDL_WarpMouse to set the position, but it seems that this one does not work properly as well. Can some one help me? I don't mind losing SDL, but i would like to make the the "look around" with mouse multiplataform and i only know how to do it in windows.

I just use a "handle input" type function like so (this is just the 'skeleton' version of the function, without any functionality filled in except for the mouse position handling which you asked about).

I am not sure if you already have an event handling loop in yr SDL app, but it should be only run once per frame. <br><br>Here is a small snippet with all other event handling not included:<br><pre><br>while( SDL_PollEvent( &event ) )<br> {<br> if( event.type == SDL_MOUSEMOTION )<br> {<br> xMouse = event.motion.x; // (x/y)Mouse variables are member<br> yMouse = event.motion.y; // variables of the player class<br> // that tracks mouse movement.<br> }<br> }<br></pre><br><br><br>Here is more of a complete (skeleton) event handling loop to see the overall context:<br><!–STARTSCRIPT–><!–source lang="cpp"–><div class="source"><pre><br><span class="cpp-keyword">int</span> Player::handle_input(SDL_Event event)<br>{<br> <span class="cpp-comment">// This function is the event handler function.
