The Stop behavior suspends parameter animation (created by keyframes or applied behaviors) of an object. For example, if you assign the Stop parameter behavior to the Position parameter of an object moving across the screen and rotating, the object ceases to move across the screen but continues to rotate.

Each behavior’s effect on the object is frozen at the first frame of the Stop behavior in the Timeline. Keyframes applied to that parameter cease to have any effect for the duration of the Stop behavior in the Timeline. If the Stop behavior is shorter than the object to which it’s applied, all keyframes and behaviors affecting that channel immediately take effect after the last frame of the Stop behavior. For more information, see Stop a behavior.

Adjust this behavior using the control in the Behaviors Inspector:

  • Apply To: A pop-up menu that shows the parameter being stopped, and that can be used to reassign the Stop behavior to another parameter.
