Action keyframes
One-off events over the course of an animation.
Where a normal keyframe describes a state, an action keyframe triggers something the moment the playhead reaches it.
Actions
| Action | Effect |
|---|---|
| Grab onto bone | The object hangs from the chosen bone from now on |
| Attach to object | The object follows another object |
| Release | Undo the attachment, the object stays where it is |
| Show | Make the object visible |
| Hide | Hide the object |
| Change costume | Put on a different costume |
Creating one
＋ Action keyframe at the playhead — pick the object and the target first, otherwise the app points that out.
