(This document covers version 0.8.1 of the 'Progress Bar' behavior, current as of 2005-Feb-11)
Description
Place this behavior on an object that you want to change as another object is loading data dynamically. As the
Loader Object
fires
onLoadProgress
events, this behavior will modify the parent object, setting the property specified by
Property Name
to a value between the
Min Value
and
Max Value
that you specify, based on how far the load has progressed.
If the
Start At Min?
advanced property is checked, this behavior will automatically set the property to
Min Value
as soon as the behavior loads.
If
Show Percent?
is checked, this behavior will update the contents of another text object (chosen with the
Pct Text
property) to be a string showing the percent complete. (The percent will always be an integer, such as “47%”.)
The common case is to set the property to something like a scale value, and set the
Loader Object
to a Preload Module behavior, to cause a progress bar to grow as the module loads. However, this behavior can really be attached to any object: you can cause the light level to slowly rise as models load (set the
brightness
of a Point light), cause an object to spin faster and faster (set the
rotationVelocity.x
property), and so on.
Basic Properties
Loader Object
The object which will be firing onLoadProgress events.
Property
The script name of the property on the parent to control.
Min Value
The value of the property when at 0% loaded.
Max Value
The value of the property when at 100% loaded.
Advanced Properties
Start at Min?
Initialize the property to be the minimum value?
Show Percent?
Update a text object with percent information?
Pct Text
The Text object whose string should be updated with percent information.
