External Forces 模块

此属性可修改__风区__和粒子系统力场对系统发射的粒子的影响。

Using the External Forces module

This module is part of the Particle System component. When you create a new Particle System GameObject, or add a Particle System component to an exiting GameObject, Unity adds the External Forces module to the Particle System. By default, Unity disables this module. To create a new Particle System and enable this module:

1. Click GameObject > Effects > Particle System.
2. In the Inspector, find the Particle System component.
3. In the Particle System component, find the External Forces module fold-out.
4. To the left of the fold-out header, enable the checkbox.

API

Since this module is part of the Particle System component, you access it through the ParticleSystem class. For information on how to access it and change values at runtime, see the External Forces module API documentation.

属性

For some properties in this section, you can use different modes to set their value. For information on the modes you can use, see Varying properties over time.

详细信息

要通过此功能获得最佳效果，请使用 ParticleSystemForceFields 组件创建单独的游戏对象。

_地形__可添加_风区_来影响树在景观中的运动。启用此部分的功能允许风区吹动系统发射的粒子。通过 Multiplier_ 值可调整风对粒子的影响，因为风对粒子的吹动作用通常比树枝更强烈。
