animmixer
Creates a marker for an animation clip. Markers let you highlight and annotate frames in clips, such as marking a start frame and end frame on a clip to set up a transition. You can create markers on any type of Clip (for example, action, shape or audio).
oReturn = AddMarker( Model, Container, [Time], [Duration], [Name] ); |
Returns the marker as a CollectionItemLegacy object.
| Parameter | Type | Description |
|---|---|---|
| Model | String | The model to add the marker to. |
| Container | String | The container on which to create the marker. Could be a compound, a track, a clip... |
| Time | Double | Frame at which to add the marker.
Default Value: Current frame. |
| Duration | Double | Duration of the marker.
Default Value: Default value is 0 (a single-frame marker). |
| Name | String | Name of the new marker. |

' the object makes in the Y-axis.
