View source for Picnum

'''picnum''' is a member of the sprite and wall structures.

For related members of other structures, see [[overpicnum]], [[floorpicnum]], and [[ceilingpicnum]].

A '''picnum''', short for "picture number", also referred to as '''tilenum''', short for "tile number", is the index of any piece of art in the game.  In CON coding, since [[actor]] types are defined by tile number, the picnum of a sprite determines the code that will be executed on it.  For example, any sprite that is given a picnum of 2000 in the code or in a map is thereby a PIGCOP (because the label 'PIGCOP' is defined as 2000) and will then execute the associated code.

In the code of a specific [[actor]] type, the picnum of the sprite executing the code is already known.  But in certain events, such as [[EVENT_GAME]], different actor types will execute the same [[onevent]] code, so getting the value of picnum can be very useful.
