View source for Parallaction/Scripts/Zone flags

=== closed ===

Used to mark closed doors (doors are open by default). This doesn't prevent them to be opened by the character.

=== active ===

Active zones and animations are visible and are available for interaction.

=== remove ===

Signals that a zone or animation is to be deactivated and made invisible at next frame.

=== acting ===

This flag is set by the START command. It indicates the script attached to the animation is being executed.

=== locked ===

Marks a DOOR zone that cannot be activated (opened). It is always used in conjuction with the CLOSED flag, so the final effect is exactly that of a GET zone with a FIXED flag. The duplication is needed because the graphic formats for DOOR and GET zones are slightly different (why!).

=== fixed ===

Marks a GET zone that cannot be activated (picked up).

=== noname ===
Tells the engine there is no label for this zone. (The need for this flag is not clear: isn't it enough to leave out the LABEL statement?)

=== nomasked ===
Keeps an animation to the nearest Z level, meaning it is superimposed on the screen regardless of the background mask. 

=== looping ===
Has the animation script (SCR) repeating indefinitely.

=== added ===
Never used in Nippon Safes.

=== character ===
Marks animations whose Z coordinate need to be computed each frame. They typically are non-playing characters wandering around the game.

=== nowalk ===
When a zone with NOWALK flag is activated, the character is not set to move to any particular position before action actually takes place. Zones without this flag always have a MOVETO statement specifying the needed character position.
