Half Range: When this checkbox is selected, the sine (or other wave shape) wave is
essentially cut in half and does not cross over the value of 0. For example, when Amplitude
is set to 100, the parameter oscillates between 100 and –100. When Half Range is selected,
however, the parameter oscillates between 100 and 0. When Amplitude is set to –100,
the parameter oscillates between –100 and 0.
Tip: When you are oscillating position parameters, set Wave Shape to Sine and enable
Half Range to create a bouncing effect.
The dotted line
represents 0. When Half
Range is disabled, the
parameter oscillates
between the Amplitude
value and its inverse,
such as 100 and –100.
The dotted line
represents 0. When Half
Range is enabled, the
parameter oscillates
between the Amplitude
value and 0.
Start Offset: A slider that lets you delay the beginning of the behavior’s effect relative
to the first frame of its position in the Timeline. Adjust this parameter to make the behavior
start later. The units of this parameter are in frames.
End Offset: A slider that lets you offset the end of the behavior’s effect relative to the
last frame of its position in the Timeline, in frames. Adjust this parameter to make the
behavior stop before the actual end of the behavior in the Timeline. Using this slider to
stop the effect, instead of trimming the end of the behavior in the Timeline, freezes the
end of the effect for the remaining duration of the object. Trimming the end of the
behavior resets the object to its original parameters.
Apply To: The Apply To (Go) pop-up menu shows the parameter being affected and can
be used to reassign the behavior to another parameter.
