This stock works fine for CS:S. Don't know about other games though.

PHP Code:

stock SetThirdPersonView(client, bool:third)
{
    if(third)
    {
        SetEntPropEnt(client, Prop_Send, "m_hObserverTarget", 0); 
        SetEntProp(client, Prop_Send, "m_iObserverMode", 1);
        SetEntProp(client, Prop_Send, "m_bDrawViewmodel", 0);
        SetEntProp(client, Prop_Send, "m_iFOV", 120);
    }
    else
    {
        SetEntPropEnt(client, Prop_Send, "m_hObserverTarget", -1);
        SetEntProp(client, Prop_Send, "m_iObserverMode", 0);
        SetEntProp(client, Prop_Send, "m_bDrawViewmodel", 1);
        SetEntProp(client, Prop_Send, "m_iFOV", 90);
    }
}
