info_game_event_proxy is a point entity available in all Source games since Left 4 Dead.

It is an entity that triggers a game event (for example show a hint).

Note:Whenever a hint is shown to the player, a count of how many times the player was notified is recorded in the save/game_instructor_counts.txt file which is found in the Left 4 Dead save folder. After a certain threshold, certain tips will no longer show up, possibly depending on how many success entries. If you want hints to begin showing up again, open your game_instructor_counts.txt file and delete the corresponding thread, or load up the game and enter gameinstructor_reset_counts in the console(the latter will reset all of the instructor lessons.)
