When animating objects and properties in Blender, Actions record and contain the data. As everything else in Blender, Actions are data-blocks.
So when you animate an object by changing its location with keyframes, the animation is saved to the Action.
Each property has a channel which it is recorded to, for example,
Cube.location.x is recorded to Channel X Location.
The X location and Y location properties can be shared across multiple objects,
if all objects have X location and Y location properties beneath them.
Record and contain animation data.
Are groups of channels.
F-Curves are used to interpolate the difference between the keyframes.
Keyframes are used to set the values of properties bound to a point in time.
Working with Actions
When you first animate an object by adding keyframes, Blender creates an Action to record the data.
If you are making multiple actions for the same object, press the shield button for each action. This will give the actions a Fake User and will make Blender save the unlinked actions.
Objects can only use one Action at a time for editing. The NLA Editor is used to blend multiple actions together.
- Manual Frame Range
Manually specify the intended playback frame range for the action (this range is used by some tools, but does not affect animation evaluation). The manual frame range feature can be toggled with the checkbox.
When the range is set, it is used instead of the actual range occupied by key frames when adding a new track based on the action to NLA. It can also be used by exporters to determine the range of frames to export.
The range is displayed in the background of the editor as diagonal hash fill, to distinguish it from the solid fill of the current playback range.
The frame values are most commonly expected to be integers, but can be fractional.
- Cyclic Animation
Specifies that the action is intended to be cyclic over the specified range. The first and last frames of the range should represent the same pose of the cycle one loop apart, i.e. the range should include the duplicated initial key of the loop.
This option signifies intent and does not make the action cycle on its own. However, if Cycle-Aware Keying is enabled, it will automatically enable cyclic extrapolation and set up the loop period for curves newly added to the action.
Create and manage your own properties to store data in the action’s data block. See the Custom Properties page for more information.
