In Half-Life, there is a set of special
entity names that, if given to an entity, will cause it to be automatically triggered by certain game events involving the player(s). Note that these only function in multiplayer.
- game_playerspawn - Triggered when a player spawns.
- game_playerdie - Triggered when a player dies.
- game_playerkill - Triggered when a player kills another player.
- game_playerjoin - Triggered when a player joins the game.
- game_playerleave - Triggered when a player leaves the game.
