创建特定类型的轨道
The type of a track is defined by a parameter that it animates. Each track animates only one parameter. A parameter is a setting of an object, property, material, etc. that should be animated.
轨道的类型由它动画的参数定义。每个轨道仅对一个参数进行动画处理。参数是应设置动画的对象、属性、材质等的设置。
The article lists the types of tracks available in the Tracker and gives instructions on how to create a track of a certain type.
文章列出了 Tracker 中可用的轨道类型，并给出了如何创建特定类型的轨道的说明。
Node-Related Tracks节点相关曲目#
Node-related tracks allow animating common and type-specific node settings. For example, you can create a track that enables a node, or changes its position. Such tracks need to be bound to some specific node in the world.
节点相关的轨道允许动画常见和特定类型的节点设置。例如，您可以创建启用节点或更改其位置的轨道。这样的轨道需要绑定到世界上的某个特定节点。
Creating a Node-Related Track创建节点相关的轨道#
To create a node-related track, perform the following:要创建与节点相关的轨道，请执行以下操作：
- Click
to add a track that will animate some parameter. The Add Parameter window will open.单击 以添加将动画某些参数的轨道。 Add Parameter 窗口将打开。 -
Choose a node in the list and then choose a parameter that should be animated and click Ok.在列表中选择一个节点，然后选择一个应设置动画的参数并单击 Ok。
If you want to animate a type-specific node parameter, click + to the left of the desired node type and choose the parameter.如果要为特定类型的节点参数设置动画，请单击所需节点类型左侧的 + 并选择参数。 -
In the Select Node dialog window that opens, bind the track to a node from the list and click Ok.在打开的 Select Node 对话窗口中，将轨道绑定到列表中的一个节点，然后单击 Ok。注意You can later change the node bound to the track in the Name field of the Track Info section: double-click the field and choose a node in the list.您可以稍后在 Track Info 部分的 Name 字段中更改绑定到轨道的节点：双击该字段并在列表中选择一个节点。
注意If the track animates a type-specific parameter, it should be bound to the node of the corresponding type. Otherwise, an error message will occur.如果轨道为特定类型的参数设置动画，则应将其绑定到相应类型的节点。否则，将出现错误消息。 - Compose a track by creating the required number of key frames.通过以下方式编写曲目创造所需的关键帧数。
Common Node Parameters常用节点参数#
Common parameters of node-related tracks allow you to toggle the node on and off, change its position, orientation and scale along the X, Y, and Z axes.节点相关轨迹的常用参数允许您打开和关闭节点，沿 X, Y 和 Z 轴更改其位置、方向和比例。
Moving a Node移动节点#
The position parameter allows you to animate node movement along the axes. A spline, along which the node moves, can be visualized in the scene: enable both the track graph and Visualizer (Helpers -> Show Visualizer) in order to see the created track path.position 参数允许您为节点沿轴的移动设置动画。节点沿其移动的样条曲线可以在场景中可视化：启用 track graph 和 Visualizer (Helpers -> Show Visualizer) 以查看创建的轨迹路径。
Track Path跟踪路径For each axis, you can specify a type of velocity of the node when it moves:对于每个轴，您可以指定节点移动时的速度类型：
Types of Node Velocity节点速度的类型- Inconst velocity stands for the inconstant velocity of the node when it moves along the spline (as curves are passed faster).Inconst velocity 代表节点沿样条线移动时的非恒定速度（因为曲线通过得更快）。
- Const velocity stands for the constant velocity of the node. It will move at the uniform speed throughout the whole spline.Const velocity 代表节点的恒定速度。它将在整个样条曲线中匀速移动。
Also, you can specify the axis along which the node should be oriented when moving: choose follow X, Y or Z together with the type of velocity.
另外，您可以指定节点在移动时应沿其定向的轴：选择 follow X, Y 或 Z 以及速度类型。
 |
 |
 |
Follow X Axis |
Follow Y Axis |
Follow Z Axis |
When you choose the axis to follow, you should also specify an Offset that specifies how far along the spline is the point by which the node is oriented.当您选择要跟随的轴时，您还应该指定一个 Offset 来指定沿样条线的距离是节点所指向的点。
Offset抵消- By the default value of 0.01, the node faces the current spline point.默认值为 0.01，节点面向当前样条点。
- By higher values, the node is oriented as if it has already moved further forward the spline.通过更高的值，节点的方向就好像它已经进一步向前移动样条。
By the value of 0, the node will always be oriented along the specified axis instead of facing it along the spline.通过 0 的值，节点将始终沿指定轴定向，而不是沿样条线面向它。If you want to control the orientation of the node for the follow the axis mode, you can use a dummy node:如果要控制 follow the axis 模式的节点方向，可以使用 dummy node：
- Create a dummy node.创建一个 dummy node。
- Add your node as its child.将您的节点添加为其子节点。
- Orient and position it relative the dummy however necessary.不管必要，相对于假人定向和定位它。
Rotating a Node旋转节点#
Types of Node Velocity节点速度的类型The rotation parameter allows you to rotate the node along X, Y or Z axes. For each axis, you can specify a type of velocity of the node when it rotates:rotation 参数允许您沿 X, Y 或 Z 轴旋转节点。对于每个轴，您可以指定节点旋转时的速度类型：
- Inconst velocity stands for the inconstant velocity of the node when it rotates (with acceleration).Inconst velocity 代表节点旋转时（带加速度）的非恒定速度。
- Const velocity stands for the constant velocity of the node. It will rotate at the uniform speed.Const velocity 代表节点的恒定速度。它会匀速旋转。
Also, you can specify an order of rotations about the axes: choose order XYZ or order ZYX together with the type of velocity. For example, if rotating the sun (a world light source), the order should be ZYX.此外，您可以指定围绕轴的旋转顺序：选择 order XYZ 或 order ZYX 以及速度类型。例如，如果旋转太阳（世界光源），则顺序应为 ZYX。

Track-Based Track基于轨道的轨道#
These tracks allow for convenient mixing between different complex tracks (i.e. saved *.track files with a number of tracks inside).这些轨道允许在不同的复杂轨道之间方便地混合（即保存的 *.track 文件，其中包含许多轨道）。
For example, if there are saved tracks files that control day-night shift and tracks that contain weather conditions (windy, cloudy and rainy weather, loading them as track tracks allow you to set the day time while controlling the amount of wind, rain, and cloudiness.例如，如果保存的曲目文件控制昼夜班和包含天气条件（大风、阴天和下雨的天气）的曲目，将它们加载为曲目曲目允许您设置白天时间，同时控制风量、雨量、和浑浊。
Mixing Different Tracks混合不同的曲目#
- Add the track track.添加 track 轨道。
