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 pop-up menu shows the parameter affected and can be used
to reassign the behavior to another parameter.
HUD Controls
The HUD lets you adjust the Phase, Amplitude, Speed, and Half Range parameters as well
as change the parameter assignment of the Oscillate behavior.

Creating a Decaying Oscillation
When you are oscillating an object’s rotation or position, a common effect is to “decay”
or “dampen” the animation over time. This means that the animation gradually slows or
comes to a stop. You can achieve this effect using keyframes to slow the amplitude of
the oscillation.
To decay an oscillating rotation using keyframes
1 Go to the frame where you want the animation to begin, then enable Record (press A).
2 Set the Amplitude to the maximum value you want to use in your project.
Note: When Record is enabled, any value change to a parameter using the Inspector,
HUD, or Canvas creates a keyframe.
3 Go to the frame where you want the animation to come to a stop and set the Amplitude
value to 0.
