When you click the 3D button, additional 3D controls become available. The center arrow now
defines the direction the object is thrown in 3D space (X, Y, and Z axes). The Speed slider lets you
increase or decrease the velocity of the thrown object.
Adjusts velocity of throw
Adjusts direction in X, Y,
and Z space
In the 2D and 3D Throw HUDs, press the Shift key while dragging the arrow to constrain it to 45
degree angles. In the 2D HUD, press the Command key to change the arrow’s direction without
affecting its length.
Note: The maximum speed you can define with the HUD is not the maximum possible speed.
Higher values can be entered into the Throw Velocity/Throw Distance parameter in the
Behaviors Inspector.
Parameter behaviors
Parameter behaviors overview
A Parameter behavior is applied to a specific object parameter, and the effect is limited to just
that parameter. The same Parameter behavior can be added to different parameters, resulting in
different effects. For example, you can apply the Oscillate behavior to the opacity of an object
to make it fade in and out, or you can apply Oscillate to the rotation of an object to make it
rock back and forth. You can also apply Parameter behaviors to filter parameters, generator
parameters, the parameters of particle systems, or even the parameters of other behaviors.
Examples include Oscillate, Randomize, and Reverse.
For a description of each Parameter behavior, see the behavior list in the Help table of contents
(the sidebar to the left of this window).
Audio
The Audio behavior lets you animate nearly any parameter based on properties of an audio
file, such as bass frequency. For example, the Audio parameter behavior can be applied to the
Scale parameter of an object, causing the object to scale up and down based on the amplitude
of the bass. For more information on using the Audio parameter behavior, see
Apply the Audio
parameter behavior on page 1026.
