Contextual Ping System

Communication in Left 4 Dead has never been this easy!

This addon features 3 ways of pinging:

- Automatic voice: when survivors spot items and enemies, and verbally call them out. (bots use this!)
- Manual voice: when chat wheel commands are issued
- Manual button: when users press their chosen key (bound to "+alt2") to ping anywhere anytime ( bind T +alt2 )


Both the server host and the players need to install for players to see and hear the pings.

It does not work on official Valve servers.

To change settings in-game, the server host can type !ping_system in the chat. Then use !ping_system savecfg to save the changes, or !ping_system loadcfg to load settings from a previously saved configuration.

Available commands:

DisableAutoPing options:
0: enable all auto pings
1: disable all auto pings
2: only disable special infected warning pings
3: only disable item pings

Example:

No auto-pings for special infected

Only 2 pings per player

Set every ping duration to 3.5 seconds

Set enemy warning ping duration to 1.5 seconds

Set first aid kit ping duration to 30 seconds

These commands are partially matched. For instance, all commands below are identical.

Inside the settings file:

Custom ping icons can be made by replacing the corresponding "ping_system/icon_item.vtf" file(s) (required VTF flags: Clamp S, Clamp T, No mipmap). All edge pixels on these images need to be fully transparent.

Pings can be listened for with the script event "player_ping{ CBasePlayer player, Vector origin, CBaseEntity target }".
