Hi. I am new to SDL to be kind if I am doing something wrong 
I am just
printing out the x, y co-ords of the mouse as it moves (I print this in the
event section for mouse motion). If I move the mouse very slowly it is fine
and updates. If I move the mouse fast around the window it will stop
printing briefly, and then start again. If I try pressing a key during this
pause, it misses it (for example, I use ESC to quit, and if I press escape
during the pausing, it doesn’t quit like it should).
Here is basically what my program looks like so far (if you need more
specifics I can give those). This is all in main.
bool bQuit = false;
bool bKey[256];
Uint16 xMouse, yMouse;
Init SDL and OpenGL
SDL_EnableUNICODE (1);
while (!bQuit)
{
UpdateInput ();
}
UpdateInput looks something like this (hopefully it formatting looks ok,
it’s a bit hard in outlook).
while (SDL_PollEvent (&event))
{
switch (event.type)
{
case SDL_KEYDOWN:
bKey[event.key.keysym.sym] = true;
break;
case SDL_KEYUP:
bKey[event.key.keysym.sym] = false;
break;
case SDL_MOUSEMOTION:
xMouse = event.motion.x;
yMouse = event.motion.y;
printf ("(%i, %i)\n", xMouse, yMouse);
break;
case SDL_MOUSEBUTTONDOWN:
mouseButton[event.button.button] = 1;
break;
case SDL_MOUSEBUTTONUP:
mouseButton[event.button.button] = 0;
break;
case SDL_QUIT:
bQuit = true;
break;
}
default:
break;
}
}
