animation
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.
ScaleAndOffset is the command equivalent of moving or scaling a
keyframe region in the dopesheet. It should be used when trying to
emulate dopesheet behaviour. The Sequence command is similar in effect but is
the command equivalent of doing Animation > Sequence Animation.
When emulating Animation > Sequence Animation behaviour, use
Sequence instead.

Parameter | Type | Description | ||||||
---|---|---|---|---|---|---|---|---|
InputObjs | String | 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 | siParameterScope | Parameter scope of the operation.
Default Value: siAnimatedParameters |
||||||
Offset | Double | Value of the offset you want to apply to the fcurve(s). Value range -Inf, +Inf |
||||||
Scale | Double | Value of the scaling factor you want to apply to the
fcurve(s). Value range 0, +Inf |
||||||
StartFrame | Double | Start frame of the region of the fcurve(s) you want to
operate. Value range -Inf, +Inf |
||||||
EndFrame | Double | End frame of the region of the fcurve(s) you want to
operate. Value range -Inf, +Inf |
||||||
Pivot | Double | Pivot frame is the frame w.r.t which you wish to scale. Value range 0, +Inf |
||||||
Ripple | Boolean | Ripple effect of resulting fcurve.
|
||||||
Mode | siSequenceMode | Affected items for SequenceAll only.
Default Value: siFCurvesAnimationSources |
||||||
Discrete Time | Boolean | Make sure that all the keys will fall on frames.
|
||||||
SelectedKeysOnly | Boolean | True to scale and offset only the selected keys within the
timerange (from StartFrame to EndFrame). To create or modify a key
selection, use the SelectKeysInTimespan command. By default (false), this command operates on all keys within the timerange. Default Value: False
|
||||||
Layer | Integer | Animation layer to scale and offset
Default Value: All layers (-1) |
