Parameter

参数

Define the speed and direction of the particles.

定义粒子的速度和方向。

Change
Direction[XYZ ]
Variation[0..180°]
Speed[-∞..+∞]
Variation[0..100%]

转向[ XYZ ]变化[0.180 ° ]速度[-∞ . . + ∞]变化[0.100% ]

You can change the velocity of the particles using one of three modes.

你可以用三种模式中的一种来改变粒子的速度。

Speed&Direction

速度与方向

In this mode, you can change both the speed and direction of the particles. Set the Speed and Direction values to the desired speed and direction of the particles. You can vary the Speed and Direction values using the Variation parameters.

在这种模式下，你可以同时改变粒子的速度和方向。将速度和方向值设置为粒子的期望速度和方向。您可以使用变化参数改变速度和方向值。

Speed

速度

Only the speed (length of the vector) will be changed. Set Speed to the desired speed of the particles. You can vary the Speed value using the Variation parameter.

只有速度(矢量的长度)会改变。将速度设置为粒子的期望速度。您可以使用 Variation 参数改变速度值。

Direction

方向

Only the direction (alignment of the vector) will be changed. Set Direction to the desired direction of the particles. You can vary the Direction value using the Variation parameter.

只有方向(矢量的对齐方式)会改变。将方向设置为粒子的预期方向。您可以使用 Variation 参数改变 Direction 值。

Evaluation Type

评估类型

Defines how the particles are influenced by the speed or direction or both. Depending on the setting chosen, the current speed or direction or both of the particles will be replaced, added to or multiplied by the node’s speed and direction settings.

定义粒子如何受到速度或方向或两者的影响。根据所选择的设置，当前的速度或方向或两个粒子将被替换，添加到或乘以节点的速度和方向设置。

Per Second

每秒

If this option is enabled, the node is evaluated once per second; otherwise, it is evaluated once per frame. It is important to enable this option when Evaluation Type is set to Multiply or Add. In Replace mode, the setting has no effect.

如果启用此选项，则每秒计算节点一次; 否则，每帧计算一次。当评估类型设置为乘法或加法时，启用此选项非常重要。在替换模式下，设置没有效果。

Additional input ports:

其他输入端口:

• On

•安

A Boole value of True switches the node on; a value of False switches it off.

值为 True 的 Boole 将打开该节点; 值为 False 将关闭该节点。

• Animation Time

•动画时间

Since the node’s parameters can be keyframe animated, by default the Cinema 4D time is used internally to ensure that the values are interpolated correctly. However, you can pass your own time value to this port. This should be of the data type Time, which is a Real number in the simplest case. If no value is passed, Cinema 4D’s time is used.

由于节点的参数可以是关键帧动画，默认情况下 Cinema 4D 时间在内部使用，以确保值被正确插值。但是，您可以将自己的时间值传递到此端口。这应该是数据类型 Time，在最简单的情况下，它是一个实数。如果没有值传递，使用 Cinema 4D 的时间。

• Particle

•粒子

Connect this port to the stream of particles whose velocity you want to change, such as to the Particle output port of a PPass node.

将此端口连接到要改变其速度的粒子流，例如 PPass 节点的粒子输出端口。
