1) pridas 2 cvary pod nazvem 'custom_fov' a 'fov_zoom'
2) usermsg.cpp
pridas toto:

////////////////////
Do funkce SetFOV:

BEGIN_READ(pbuf, iSize);
    int iFOV = READ_BYTE();
    g_Local.iFOV = iFOV;

    if (iFOV == 90)
    {
        g_Local.bScoped = false;
    }
    else if (iFOV > 0)
    {
        g_Local.bScoped = true;
    }
    if (cvar.custom_fov > 0 && !g_Local.bScoped)
    {
        iFOV = cvar.custom_fov;
        return (*pSetFOV)(pszName, iSize, &iFOV);
    }
    else
    {
        iFOV = 90;

        return (*pSetFOV)(pszName, iSize, &iFOV);
    }

    return (*pSetFOV)(pszName, iSize, pbuf);

A pridas novou funkci pod to

void CustomFOV()
{
    static int fov; fov = 90;
    static int fov_old;

    if (cvar.custom_fov != 90 && !g_Local.bScoped)
    {
        fov = cvar.custom_fov;
    }
    else if (!g_Local.bScoped)
    {
        fov = cvar.fov_zoom;
    }
    (*pSetFOV)("SetFOV", 1, &fov);


    fov_old = fov;

}

////////////////////

3) do Usermsg.h
pridas toto:

////////////////////

extern void CustomFOV();

////////////////////

4) a pak zavolas funkci CustomFOV ve cl_createmove.

client.cpp
ve funknci cl_createmove

////////////////////

CustomFOV();

////////////////////

to je vse
