How to setup HC with faster
A HC is a way to load off AI Decision Making, Pathfinding, Line-Of-Sight Checks etc away from the "main server" by handing over control of a set of placed AI to a special "dedicated client" that also connects to the server.
Ideally runs on the same mashine as the server to avoid any network delay. Its basically ArmA's way of Multi-Threading.
The mission needs to have a Headless Client Module present. Without it, the client cannot connect and wont do anything. Most missions like Antistasi, Hearts and Minds, will come with HC slots already.
- ServerProfile/Profile/Mods The HC needs to load the same mods like any player client would, but there are a few exceptions. For example, User Interface Mods, Sound Mods, etc like JSRS or DUI/ShackTac Hud, can be neglected by the headless client.
Rule of thumb: whatever you can run as an optional mod can be ignored. If in doubt, just load it on the hc as well.
- ServerProfile/Server/Headless Clients
Turn them on, Headless IP should default to 127.0.0.1 if they run on the same mashine. (ideal case, avoid network delay!) Select Number of HCs. Save Profile, Run, Done.
If you want to autostart/schedule the server start in any way, you can use the HC command line that will be put in your clip-board when you start the server via faster. See Example:
