NeHe uses dinput.h in lesson23 to enable camera rotation with the mouse. Surely there must be a way to do this without using DirectX?

You could always use Windows to do that type of thing.

For the keyboard, you can use WM_KEYDOWN/WM_KEYUP and for the mouse you can use WM_MOUSEMOVE. WM_KEYDOWN/WM_KEYUP supply you with the key that is currently down/up, whereas WM_MOUSEMOVE tells you the x/y coordinates of the mouse, as well as some additional information such as which mouse keys are pressed, etc.

Hope this helps!

Blagodarya, Gladiator. Do you know of any working code examples using WM_MOUSEMOVE in a 3d game? That would be very helpful. Thanks again.

I used that once, pretty easy but its just a hack



void c_world::mmove(int dx, int dy)
{
yrot-=(100-dx)*0.05f;
xrot+=(100-dy)*0.05f;
SetCursorPos(100,100);
while (yrot > 360) yrot -= 360;
while (yrot < 0) yrot += 360;
}



void c_world::Update()
{
POINT p;
GetCursorPos(&p);
mmove(p.x, p.y);
...

this updates the globals yrot and xrot

I know its a complete hack but it works like a charm:p

One thing to keep in mind is that there is nothing wrong with using DirectX; the DX API is specifically designed with input, sound, graphics, and networking acceleration in mind, so it''s ideal for designing games or other multimedia software. In fact, a combination of DX and OpenGL (OpenGL for 3D rendering, obviously, and DX for the networking, input, and sound components) would make for a very efficient and speedy game.
The only drawback to DX, of course, is its inherent non-portability. heh But any serious game company will tell you that it is important to know and use DX because over 90% of the world uses Windows 9x, 2k, Me, or NT Operating Systems.

Just my two cents on the topic... That hack that fenrir provided does work quite well, though....

try someit like this once every frame

left_mouseButton = UNPRESSED;
right_mouseButton = UNPRESSED;

GetCursorPos(&mousePOS);

result = GetAsyncKeyState(VK_LBUTTON);
if (result&0x10000000) left_mouseButton = PUSHED;

result = GetAsyncKeyState(VK_RBUTTON);
if (result&0x10000000) right_mouseButton = PUSHED;
