List of L4D2 Instructor Messages
From Valve Developer Community
This is a list of instructor lessons that you can make appear by entering their name in the event_name field of an info_game_event_proxy.
Note:If you want to test any of these out, make sure you first open your save/game_instructor_counts.txt file and delete the contents, or load up the game and enter gameinstructor_reset_counts in the console.
Note:In order to make any of these appear, you must enable the Fire Event When First Seen flag of the info_game_event_proxy.
Note:This is not a full list of events. I've only picked the ones that can be useful in your custom maps/campaigns. Anything not mentioned here will probably automatically appear at the proper time anyway, and/or will not work when called by an info_game_event_proxy.
Entries engraved in bold are confirmed to work and can be called with info_game_event_proxy-s.
You can also use L4D Instructor messages inside L4D2. List of L4D Instructor Messages
env_instructor_hint is available in L4D2 for custom instructor messages, but multi-language support is not available. To do: confirm that there is no multilanguage support within the entity
