I found a simpler way to do it using SV_ValidClientMulticast.
PHP Code:
// Is Origin in player's potentially view set?
bool:IsOriginInPlayerPVS(const id, Float:fMessageOrigin[3])
{
static leafnum;
leafnum = OrpheuCall( SV_PointLeafnum, fMessageOrigin );
return bool: OrpheuCall( SV_ValidClientMulticast, id, leafnum, MSG_PVS );
}
all i need are the signatures
