侧栏(Sidebar) ‣ 编辑的动作(Edited Action)

Contains settings for the object’s active action. Only visible if the Action Track is selected.

动作

A data-block menu where you can see, change, and clear the object’s active action. See also the Action Editor’s Action.

外插

Determines whether the action will influence the frames before/after its boundaries once it has been pushed down into a strip. (As long as it’s still the active action, Hold is used regardless of the choice.)

• 保持

  The property values at the action’s first keyframe also apply to the earlier frames (if the strip is the first in the track). The values at its last keyframe also apply to the later frames (up to the next strip).

  保持前进

  The property values at the action’s last keyframe also apply to the later frames (up to the next strip).

  无

  The animated properties return to their default values outside of the strip boundaries.

混合

How to combine the action’s property values with those of the tracks below.

• 替换

  Overwrites the values produced by the lower tracks. If Influence is less than 1, a linear interpolation between the previous and new values is used instead.

  相乘，相减，相加

  Blends the action’s values with those of the lower tracks using a simple calculation. If Influence is less than 1, a linear interpolation between the previous values and these calculated values is used.

  \(result = mix(previous, previous (+-×) value, influence)\)

  合并

  根据每个属性的类型，自动选择以下方法之一：

  • 轴/角度旋转

    \(result = previous + value × influence\)

    这导致平均轴并增加旋转量。

    四元数旋转

    四元数学同时应用于属性的所有四个通道：

    \(result = {previous} × {value} ^ {influence}\)

    成比例（缩放）

    \(result = previous × (value / default) ^ {influence}\)

    其他

    \(result = previous + (value - default) × {influence}\)

  Note

  Since this blending mode uses quaternion multiplication to calculate the Quaternion Rotation properties, it always drives all four channels during playback, and Insert Single Keyframe is forced to insert all four keys. Other types of channels can still be keyed individually.

影响

How much the action contributes to the result of the NLA stack.

片段

名称

片段的名称。

开关（复选框）

When unchecked, the strip will no longer contribute to the animation. It’s shown with a dotted outline to indicate this.

活动片段

参考

面板:

侧栏(Sidebar) ‣ 片段(Strip) ‣ 活动片段(Active Strip)

Contains common strip properties.

起始帧

The frame where the strip begins. Changing this will move the strip while keeping its duration constant.

结束帧

The frame where the strip ends. Changing this will also change the Action Clip Frame End, thereby cropping or extending the action. If you instead want to speed it up or slow it down, scale it by using Strip ‣ Transform ‣ Scale or adjusting the Playback Scale setting.

外插

参见 外插。

混合

参见 混合。

淡入 / 淡出

How many frames it takes for the strip’s influence to ramp up at the start and wind down at the end.

自动混入 / 混出

Calculates Blend In/Out automatically by looking at the strips in the track above or below that overlap the current strip in time.

回放

• 反向

  使片段倒向播放。

  循环片段时长

  Whether to wrap the Animated Strip Time back to the start if it exceeds the Action Clip Frame End.

动画影响力

Lets you manually specify, and animate, how strongly the strip affects the animation. This is an alternative to using the (Auto) Blend In/Out settings above.

To create an influence keyframe, first type a value, then either click Insert Keyframe in its context menu or press I while hovering over it. You can see the keyframes in e.g. the Graph Editor.

动画化的片段时间

Lets you manually specify, and animate, the frame at which the underlying action is sampled.

Note

Although the setting is called Strip Time, its value is a frame number inside the action, not inside the strip. If you have an action going from frame 1 to frame 50 that’s referenced by a strip going from frame 101 to 150, you’d set the Strip Time to 1 to see the first keyframe, not 101.

In combination with Cyclic Strip Time, this lets you play the action’s keyframes multiple times in a single strip. As an example, say that the action’s keyframes are between frames 1 and 50. If you animate the strip time to instead go from 1 to 100, the keyframes will play twice (at twice the speed).

In practice, however, it’s easier to use the Repeat setting described below.

动作剪辑

参考

面板:

侧栏区域 ‣ 片段 ‣ 动作剪辑

包含特定于动作片段的属性。

动作

The action referenced by the strip.

起始帧、结束帧

How much of the action to use. By adjusting these, you can crop or extend the action (and the strip, as its Frame End will change accordingly). If you extend the action, F-Curve Extrapolation will kick in.

One case where these settings can be useful is in cyclic animation where the first and last keyframes of the action have the same value (meaning this value applies for two frames when the animation restarts). By reducing the Frame End, you can exclude the last keyframe and have the value apply for only one frame instead.

同步长度

Automatically sets Frame Start/End to the action’s first/last keyframe when exiting Tweak Mode.

当前时间点

Sets Frame Start/End to the action’s first/last keyframe.

回放比例

Makes the animation play more quickly (scale < 1) or slowly (scale > 1) than the original action.

重复

Makes the action play multiple times.
