创建特定类型的轨道

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。

注意

For players, always set follow Z, as all cameras face in the negative Z direction by default.为了球员，始终设置为 follow Z，因为默认情况下所有相机都面向负 Z 方向。

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。

注意

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：

1. Create a dummy node.创建一个 dummy node。
2. Add your node as its child.将您的节点添加为其子节点。
3. Orient and position it relative the dummy however necessary.不管必要，相对于假人定向和定位它。

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。

Common parameters of objects-related tracks allow you to toggle an object on and off, change a material or a property assigned to a surface of the object. You can also choose a specific parameter of the material or the property to animate.对象相关轨迹的通用参数允许您打开和关闭对象，更改分配给对象表面的材质或属性。您还可以选择特定的参数材质或者财产动画。

To change a material or a property set to an object surface, perform the following:要将材质或属性集更改为对象曲面，请执行以下操作：

1. • For the material, create the node -> object -> material track.对于材质，创建 node -> object -> material 轨道。
   • For the property, create the node -> object -> property track.对于属性，创建 node -> object -> property 轨道。
2. Choose an object-related node in the Select Node window that opens.在打开的 Select Node 窗口中选择一个与对象相关的节点。

3. In the Surface field of the Track Info section, choose a surface to change the material or property for.在 Track Info 部分的 Surface 字段中，选择要更改其材质或属性的表面。

   

4. Double-click the track line to select the material or property to be applied.双击轨迹线以选择要应用的材质或属性。

These parameters allow you to toggle playback of the skinned mesh animation on and off and also set animation from the .anim file.这些参数允许您打开和关闭 skinned mesh 动画的播放，还可以从 .anim 文件设置动画。

These tracks control parameters of particles (and their emitters).这些轨道控制参数粒子（及其发射器）。

These tracks control parameters of water mesh waves.这些轨道控制 water mesh 波的参数。

A player persecutor has additional settings that can be animated, namely: a target that the persecutor follows, an anchor point, a distance between the persecutor and the target, phi and theta angles. 玩家迫害者有其他设置可以动画的，即：迫害者跟随的目标，锚点，迫害者与目标之间的距离， phi 和 theta 角.

A position of the persecutor can be controlled in one of two ways:可以通过以下两种方式之一控制迫害者的位置：

• By setting the position of the target node (the node position parameter).通过设置目标节点的位置（节点position参数）。
• By changing phi and theta angles for the persecutor. This variant is also used to rotate the persecutor.通过改变迫害者的 phi 和 theta 角度。此变体也用于轮换迫害者。
