Modifying Behaviors

Each behavior has a subset (or sometimes a complete set) of parameters that appear in the HUD. In addition, all behavior parameters appear in the Behaviors Inspector.The HUD and the Behaviors Inspector reference the same parameters, so changing a parameter in one changes the same parameter in the other.

Modifying Parameters in the HUD

In general, the parameters that appear in the HUD are the most essential for modifying that behavior’s effect. Frequently, the controls available in a behavior’s HUD are also more descriptive and easier to use than those in the Behaviors Inspector, although the Behaviors Inspector might contain more controls. For example, compare the controls for the Fade In/Fade Out behavior in the Behaviors Inspector to those available in the HUD:

Figure. HUD showing Fade In/Fade Out behavior controls.
Figure. Behaviors Inspector showing Fade In/Fade Out behavior controls.

As you can see, the visual controls in the HUD consolidate two of the parameters available in the Behaviors Inspector into a single, graphical control.

To display the HUD for a behavior
  1. Do one of the following:

    • Select the behavior to modify in the Layers list, Timeline, or Behaviors Inspector.

    • Control-click an object in the Canvas, then choose a behavior from the Behaviors submenu in the shortcut menu.

      Note: If the HUD doesn’t appear, choose Window > Show HUD (or press F7 or D).

  2. Make adjustments to the behavior using the controls in the HUD.

To cycle through the HUDs of an object
Do one of the following:
  • Click the disclosure triangle in the title bar of the HUD (to the right of the title) to open a pop-up menu that displays all behaviors and filters applied to that object. Choose an item from this list to display its HUD.

  • Select an object in the Canvas, then press D to cycle forward through all available HUDs for that object. To cycle in reverse, press Shift-D.

Modifying Parameters in the Behaviors Inspector

Unlike the HUD, the Behaviors Inspector displays all available parameters (some parameters remain hidden depending on settings chosen for other parameters).

To display the Behaviors Inspector
  1. Select an object with an applied behavior.

  2. In the Inspector, open the Behaviors pane.

    Applied behaviors appear within.

Modifying Multiple Identical Behaviors Simultaneously

In most cases, you can modify the parameters of most behaviors of the same type at the same time.

Note: For simultaneous adjustment to work, the selected behaviors must be the same (such as two Throw behaviors).

To edit multiple behaviors at the same time
  1. In the Layers list or the Behaviors Inspector, Command-click to select the behaviors (of the same type) to modify.

  2. Do one of the following:

    • In the HUD titled “Multiple Selected,” adjust the parameters.

    • In the Behaviors Inspector, adjust the parameters.

      Only behaviors that apply are available. When you adjust the parameters, all selected behaviors are modified.
