BehaviourComposer: ignore everything before this.
Begin micro-behaviour:
Begin description: Become visible. End description
Show
Begin NetLogo code:
set my-visibility true
End NetLogo code
This sets the attribute my-visibility which is used to set the NetLogo hidden? primitive attribute.
Hide does the opposite of this.
Show was implemented by Ken Kahn.
BehaviourComposer: ignore everything after this.
