Zooming the Field of View

 

This is my first tutorial, so don’t kill me if there’s any mistake...

I will show you how to zoom the FOV (Field of View) like in Q3A: As long as you hold down the 3^rd mouse button, the FOV will zoom in.

All changes take place in Client.c.

 

At the top of the file, right after the includes, add this:

 

float ZoomMultiplikator = 1.0;

 

Go to the Client_SendMove() – Function and insert the following lines:

 

if (IsKeyDown(KeyLut[VK_MBUTTON], hWnd)) 

{

ZoomMultiplikator = 0.5; // Zoom camera in

}

else

ZoomMultiplikator = 1.0;

           

If you’re using the VWeap-Entity by Thomas Werth, you could also do it like this:

 

if (IsKeyDown(KeyLut[VK_MBUTTON], hWnd)) 

{

            if(b1stPerson==GE_TRUE) // only zoom if the player is in 1^st person view

ZoomMultiplikator = 0.5; // Zoom camera in

}

else

ZoomMultiplikator = 1.0;

 

Now go to the SetupCamera() – Function and change it to this:

 

static void SetupCamera(geCamera *Camera, geRect *Rect, geXForm3d *XForm)

{

            geCamera_SetWorldSpaceXForm(Camera, XForm);

            geCamera_SetAttributes(Camera, 2.0f*ZoomMultiplikator, Rect);

}

 

That’s it.
