Chapter 6 Keyframes and Curves 447
For example, it is not until you see all of the various elements in your project in concert
that you can know whether each part is behaving as it should. One object may be
fading too slowly and making another element hard to see, or a text element might
come and go so quickly that it cannot be read. With keyframing on the fly, you can
make adjustments to any slider or parameter in the program while your project is
playing. You can also interactively manipulate objects in the Canvas. Then, if you don’t
like what you did, rewind and do it again. Each time you alter a parameter, you replace
any keyframes previously assigned.
To animate a parameter on the fly using the Inspector or the Dashboard:
1 Click the Record button (or press A) or choose Mark > Record Animation to enable
record.
2 Click the Play button or press the Space bar to begin playback.
3 As your program plays back, adjust the parameter slider.
4 Disable Record.
The changes you made are recorded as keyframes for that parameter. You can view
them in the Keyframe Editor.
If you don’t like the animation you made, you can delete the keyframes and try again.
You can choose Edit > Undo (or press Command+Z) to revert to the state before you
began recording your animation, or you can manually delete the keyframes you want
to replace.
To delete keyframes, do one of the following:
m Select the keyframe, then press Delete.
m Control-click the keyframe, then choose Delete from the shortcut menu.
m Select the keyframe, then choose Delete from the Animation menu for that parameter.
Note: To delete all of the keyframes for a parameter, choose Reset Parameter from the
Animation menu in the Keyframe Editor list or Inspector.
