参数

Here you can set the mass of particles and, optionally, specify how the mass changes over the life span of the particles.

在这里，你可以设置粒子的质量，并且可以选择性地指定质量在粒子寿命内的变化。

Mass[0..+∞]
Variation[0..100%]

质量[0. . + ∞]变化[0. . 100% ]

The mass that will be assigned to the particles. The higher the value, the greater the resistance to changes (inertia). You can vary the mass using Variation.

分配给粒子的质量。值越高，对变化的阻力(惯性)就越大。你可以使用变量来改变质量。

Over Age
Age Gradient

超过年龄/年龄梯度

If Over Age is enabled, you can use the gradient to control the mass of particles based on their ages. For example, you can increase the mass of particles as they get older.

如果超龄启用，您可以使用梯度来控制质量的粒子基于他们的年龄。例如，当粒子变老时，你可以增加它们的质量。

The left edge of the gradient represents the moment the particles are born and the right edge the moment they die. Thus, the gradient covers the life span of the particles. The brightness at a position on the graph acts as a multiplier for the Mass value.

梯度的左边缘表示粒子出生的时刻，右边缘表示粒子死亡的时刻。因此，梯度覆盖了粒子的寿命。图形上某个位置的亮度作为质量值的乘数。

To create a knot, click in an empty area below the gradient and a knot of the color at that position will be added. To change the color of a knot, double-click it and choose the desired color using the system color dialog. To remove a knot, Drag & drop it away from the gradient. The small diamonds on the gradient are bias handles and they pull the interpolation of the color knots from side to side for more control over how the gradient changes.

要创建一个结，点击在一个空白区域下面的梯度和一个结的颜色在该位置将添加。若要更改结的颜色，请双击它并使用系统颜色对话框选择所需的颜色。要删除一个结，拖放它远离梯度。梯度上的小金刚石是偏置手柄，他们拉从一边到另一边的颜色节点插值，以便更好地控制梯度的变化。

Here we are changing the mass of a group of particles depending on how far away the particles are from the world origin. We’ve also put in a PGravity node with a little more work this could be a mass-dependent force field. 在这里，我们改变一组粒子的质量取决于这些粒子离世界原点的距离。我们还放置了一个 PGravity 节点，再做一点功，这可能是一个与质量相关的力场

• 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 mass values you want to change, such as to the Particle output port of a PPass node.

将此端口连接到要更改其质量值的粒子流，例如 PPass 节点的粒子输出端口。
