简介¶
The NonLinear Animation editor, or NLA editor for short, lets you animate on a higher level. Instead of working with individual keyframes, it works with actions, which are named, reusable animation segments.

主区块¶
The editor displays a stack of tracks which work like layers in an image editing program. Higher tracks take precedence over lower ones, although you can also choose to blend them.
Each track can contain any number of strips -- typically Action Strips, which are instances of actions.
The top track highlighted in orange is special: this is the Action Track. Unlike the other tracks, it doesn't contain strips -- instead, it contains the object's active action, which is where new keyframes are added to by default.
Editors like the Dope Sheet Editor normally only show the keyframes of this active action. If you want to edit another action, you can select it in the NLA editor and press Tab to enter Tweak Mode.
Tweaking an action. Notice that it's shown in both its original track and the Action Track. The active action is temporarily hidden.¶

视图菜单¶
- 框显所选 数字键盘句号.
平移和缩放视图以聚焦于所选片段。
- 框显全部 Home
平移和缩放视图以显示所有片段。
- 框显场景/预览范围
将水平视图重置为当前场景范围，如果预览范围处于活动状态，则将其考虑在内。
- 转到当前帧 数字键盘0
Centers the view on the Playhead.
- 实时更新
Whether to update other views (such as the 3D Viewport) while you're moving strips around. If disabled, the other views only get updated once you finish the move.
- 显示函数曲线的控制
Shows a graph on top of each strip that uses Animated Influence.
- 显示标记
显示标记区域（前提是已定义了任意标记）。禁用后，标记菜单也将隐藏，且标记操作在编辑器中不再可用。
- 显示自身标记
Shows action-local markers (which you can create in the Action Editor). This can be useful to align strips to each other.
Local markers shown in the NLA Editor (top) and the Action Editor (bottom).¶
- 使用时间码 Ctrl-T
以秒显示时间而不是以帧显示。
- 同步可见范围
将编辑器的水平平移和缩放比例与其他启用了此选项的时间线编辑器同步。这样，它们始终显示相同的时间段。
- 设置预览范围 P
Lets you drag a box to define a time range for previewing. As long as this range is active, playback will be limited to it, letting you repeatedly view a segment of the animation without having to manually rewind each time.
可以使用时间线编辑器的回放弹窗中的相应按钮来更改起始帧或结束帧。或者，也可以再次运行 设置预览范围。
- 清除预览范围 Alt-P
清除预览范围。
- 设置被选的预览范围 Ctrl-Alt-P
Applies a preview range that encompasses the selected strips.
- 面光

标记菜单¶
Markers are used to denote frames with key points or significant events within an animation. Like with most animation editors, they're shown at the bottom.

过滤器¶
- 仅显示已选中
Only shows tracks belonging to objects that are selected.
- 显示隐藏项
Shows tracks from objects that are hidden.
- 包含缺失的非线性动画
Shows the Action Track even if there is no action in it.
- 搜索
Filters the track list by a search term.
- 过滤集合
Select a collection to only show tracks from objects in that collection.
- 按类型过滤
按目标类型过滤轨迹。
- 数据块排序
Sorts data-blocks alphabetically to make them easier to find.
If your playback speed suffers because of this (should only really be an issue when working with lots of objects), you can turn it off.
吸附¶
The toggle button enables/disables automatic strip snapping. The dropdown button shows a popover with the following options:
- 吸附至
元素的吸附类型。
- 帧:
Snap to full frames.
- 秒:
吸附到秒。
- 最近标记:
吸附至最近的标记。
- 绝对时间对齐
When disabled, strips will move in increments of Snap To. For example, if you selected Second and have a strip that currently starts on 0:06+5, dragging it to the right will snap it to 0:07+5. Its time increases by a second, and its subsecond offset of 5 frames remains the same.
When enabled, strips will snap to multiples of Snap To. Taking the above example, the strip would snap to 0:07+0, removing the subsecond offset.
回放控制¶
The Playback Controls region contains controls and options related to playback, keying, auto keyframing, and transport.
这些设置可让您：
控制动画的预览方式及与音频的同步效果。
通过插帧集和自动插帧功能插入并管理关键帧。
Navigate the timeline using playback and transport controls.
调整帧范围并预览动画的特定片段。
