Hành Động (Actions)

When animating objects and properties in Blender, Actions record and contain the data. As everything else in Blender, Actions are data-blocks.

Actions.

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.

Graph Editor. Each channel has an F-Curve represented by the lines between the keyframes.

Hành Động (Actions)

Record and contain animation data.

Groups

Are groups of channels.

Kênh (Channels)

Record properties.

Đường Cong-F (F-Curves)

F-Curves are used to interpolate the difference between the keyframes.

Các/Số/Khung Khóa (Keyframes)

Keyframes are used to set the values of properties bound to a point in time.

Working with Actions

../_images/animation_actions_create.png

The Action data-block menu.

When you first animate an object by adding keyframes, Blender creates an Action to record the data.

Actions can be managed with the Action data-block menu in the Dope Sheet Action Editor header, or the Sidebar region of the NLA Editor.

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.

../_images/animation_actions_range.png

Actions with and without a Manual Frame Range in Dope Sheet.

It is possible to manually specify the intended useful frame range of an action via a panel available in the Dope Sheet or the NLA Editor when a channel or NLA track is selected.

Phạm Vi Khung Hình Thủ Công (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.

Hoạt Họa Tuần Hoàn (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.

Ghi chú

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.
