Description
Offsets or scales the animation of the specified objects by offsetting (stretching) or scaling (shrinking) the portion of an fcurve between a start and end frame using a specified pivot point, then translating the resulting scaled fcurve portion. You can use this command to change the timing of all animation in a scene at once.
By default, the ripple effect is active, meaning that the region offsets other keys that are further along on the timeline (to the right). The rest of the function curve is moved to the right of the inserted region, causing a ripple effect. You can turn this feature off by setting the Ripple argument to False.
This is the equivalent of Animation > Sequence Animation. It should be used when trying to emulate this behaviour through scripting. The ScaleAndOffset command is similar in effect but is the command equivalent of moving or scaling a keyframe region in the dopesheet. When emulating dopesheet behaviour ScaleAndOffset should be used.

Description |
|
InputObjs [in/out] |
List of animatable parameters (for example "cone*/kine.local.pos"). This parameter uses the Type parameter to interpret which parameters to use in this way: - If Type == siInputParameters then InputObjs is used exactly as input (either from the specified list or the animatable parameters on the selected objects). - If Type == siAnimatedParameters then InputObjs is expected to be a list of objects on which each animatable parameter will be affected. - If Type == siAllAnimatedParameters then the value of InputObjs is ignored and instead the command uses all animated parameters on all objects in the entire scene. Default Value: If no value is specified for this parameter, the Object List will use the selected objects or parameters respecting the scope indicated by the Type argument.
|
|
|
Type |
Parameter scope of the operation. Default Value: siAllAnimatedParameters |
|
|
Offset [in/out] |
Value of the offset you want to apply to the animation. Default Value: 0 |
|
|
Scale [in/out] |
Value of the scaling factor you want to apply to the animation. Default Value: 1 |
|
|
StartFrame [in/out] |
Start frame of the region on which to operate. Default Value: 1 |
|
|
EndFrame [in/out] |
End frame of the region on which to operate. Default Value: 100 |
|
|
Pivot [in/out] |
Pivot frame for the scaling. Default Value: 1 |
|
|
Mode [in/out] |
Affected items for SequenceAll only. Default Value: siFCurvesAnimationSources |
|
|
Ripple |
Turn the Ripple effect on or off. Default Value: 1 |
|
|
Discrete Time |
Make sure that all the keys will fall on frames. Default Value: 1 |
