client.cpp
anywhere add this: Code:

void handleContinuousZoom()
{
  const char PROC_NAME[50] = "handleContinuousZoom\0";

    if( cvar.czoom == 1000 ) // leave zoom
  {
      // reset zoom
      iCurrentFOV = 90;
      fCurrentFOV = 90.0;
      (*SetFOVOrg)("SetFOV", 1, &iCurrentFOV);
     
      // prevent further zooming
      cvar.czoom = 0;
  } else    {
      // advance/decrease zoom level
      iCurrentFOV -= cvar.czoom;
      BOUND_VALUE(iCurrentFOV,10,90);
      fCurrentFOV = iCurrentFOV;

      (*SetFOVOrg)("SetFOV", 1, &iCurrentFOV);
  }
}

then find this: Code:

int HUD_Redraw

under line: Code:

hudDrawInfoTexts();

add this: Code:

if (cvar.czoom)        { handleContinuousZoom(); }

cvar.pp Code:

REGISTER_CVAR_INT( czoom ,0)

cvar.h Code:

int czoom;
