Events
Events are special occurences in the game engine, including specific key presses, display calls, etc. Events are also the only of the three CON entry points (the other two being actor and eventloadactor code) that may recurse, for example through EVENT_EGS, EVENT_SPAWN or EVENT_KILLIT.
Please see the EDuke32 event list for a complete list of all currently valid events in EDuke32. Also see onevent.
