Description
System message and event handler; contains Lingo that generates a list of definitions and labels
for the parameters that appear in a behavior’s Parameters dialog box.
Place the
on getPropertyDescriptionList
handler within a behavior script. Behaviors that
don’t contain an
on getPropertyDescriptionList
handler don’t appear in the Parameters
dialog box and can’t be edited from the Director interface.
The
on getPropertyDescriptionList
message is sent when any action that causes the
Behavior Inspector to open occurs: either when the user drags a behavior to the Score or the user
double-clicks a behavior in the Behavior inspector.
The
#default
,
#format
, and
#comment
settings are mandatory for each parameter. The
following are possible values for these settings:
Example
The following handler defines a behavior’s parameters that appear in the Parameters dialog box.
Each statement that begins with
addProp
adds a parameter to the list named description. Each
element added to the list defines a property and the property’s
#default
,
#format
, and
#comment
values:
on getPropertyDescriptionList
description = [:]
description.addProp(#dynamic, [#default:1, #format:#boolean, \
#comment:"Dynamic"])
description.addProp(#fieldNum, [#default:1, #format:#integer, \
#comment:"Scroll which sprite:"])
description.addProp(#extentSprite, [#default:1,#format:#integer, \
#comment: "Extend Sprite:"])
description.addProp(#proportional, [#default:1,#format:#boolean, \
