animation
Saves key frames on parameters at a given frame. When you invoke
this command on a parameter not already driven by an FCurve, a new
FCurve is automatically created.
The tolerance argument can be used to merge all keys within a
certain range. The range is defined as Frame - Tolerance and Frame
+ Tolerance. The merged key will inherit the constraints of the
nearest key within this range.
SaveKey( [InputObjs], [Time], [Value], [Tolerance], [Layer], [ModifiedOnly], [AutokeyScope] ); |
| Parameter | Type | Description | ||||||||
|---|---|---|---|---|---|---|---|---|---|---|
| InputObjs | String | List of animatable parameters (for example
"cone*/kine.local.pos").
Default Value: If no
argument is specified, the current marking is used. |
||||||||
| Time | Double | Frame at which to set the key.
Default Value: If no argument is specified, the current frame is used. |
||||||||
| Value | Number | Key frame values.
Default Value: Parameter values at current frame. |
||||||||
| Tolerance | Double | Frame tolerance
Default Value: Nearest 0.5 frame (-1)
|
||||||||
| Layer | Integer | Animation layer to set keys on
Default Value: Current animation layer (-1) |
||||||||
| ModifiedOnly | Boolean | If true keys will only be set for parameters that have been
modified at the current frame
Default Value: False |
||||||||
| AutokeyScope | Integer | Specifies whether keys will be set on all parameters or only
those with existing fcurves or keys.
Default Value: All specified parameters (0)
