(This document covers version 2.1.2 of the 'Jitter' behavior, current as of 2005-Feb-11)
Description
The
Property Name
is specified relative to the behavior’s parent. For example, ‘rotation.x’ refers to the x value of the ‘rotation’ property on the object to which the behavior is attached.
The
Jitter Amount
property is maximum amount to deviate from the initial value. (For example, if the original value of the property is 75, and
Jitter Amount
is set to 15, the property will jitter to values between 60 and 90.)
The
Jitter Time
property is the number of seconds it takes to complete each jitter. (Larger is slower; a value of 0.1 will cause the property to reach an extreme value 10 times a second, while a value of .5 will only reach an extreme value 2 times per second.)
If
Start Immediately?
is not checked, the behavior will not do anything until the
Start
action is called.
To change the value around which the jitter occurs, use the
Set Center Value
action (or call the setCenter method of this behavior in script).
