Adding Proximity Voice

Hello today I am going to be showing you how to create proximity chat for HL2MP mod or equivalent. First thing you are going to need to do is open game/shared/voice_gamemgr.cpp

Then go to around line 226...

bool bProximity = false;

Change that to...

bool bProximity = true;

Next you need to change the distance at which it will project the voice. Locate line 104 and change ...

m_iProximityDistance = -1;

To something like this...

m_iProximityDistance = 10;
