EVENT EGS
EVENT_EGS (aka Enter Game Spawn) is a Game Event.
This event is triggered when any sprite is spawned on the map. Like EVENT_GAME, this event run for all actors, thus the gamevar THISACTOR refers to the ID of the sprite that is executing the code.
This event occurs the moment a sprite is spawned.

In this case, the PIGCOP palette will be 1, because the EVENT_EGS code is triggered before the lines below the spawn command.
This event does not run for sprites present in the map file. For those, try EVENT_SPAWN or EVENT_LOADACTOR.
