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.

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 hilighted 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 Timeline and 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.

过滤器#
- 仅显示选中
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
按目标类型过滤轨道。
- 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/框:
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.
