ParticleSystem

描述

Script interface for the Built-in Particle System. Unity's powerful and versatile particle system implementation.

**常规参数**

粒子系统的常规参数保存在一个特殊的主模块中。在 Inspector 中，这些参数显示在所有其他模块上方：



在脚本中，可以通过 ParticleSystem.main 访问这些参数。

Accessing module properties

Particle System properties are grouped by the module they belong to, such as ParticleSystem.noise and ParticleSystem.emission. These properties are structs, but do not behave like normal C# structs. They are simply interfaces directly into the native code, so it is important to know how to use them, compared to a normal C# struct.

The key difference is that it is not necessary to assign the struct back to the Particle System component. When you set any property on a module struct, Unity immediately assigns that value to the Particle System.

Also, because each module is a struct, you must cache it in a local variable before you can assign any new values to the module. For example, instead of:
ParticleSystem.emission.enabled = true; // Doesn't compile
write:
var emission = ParticleSystem.emission; // Stores the module in a local variable
emission.enabled = true; // Applies the new value directly to the Particle System


**模块效果乘数**

每个模块都有一些特殊的乘数属性，利用这些属性，您可以在不编辑曲线本身的情况下更改曲线的整体效果。这些乘数属性全部以它们影响的曲线命名 - 例如，ParticleSystem.emission.rateMultiplier 控制 ParticleSystem.emission.rate 在给定系统中的整体效果。

**常量值的简写表示法**

对于简单的常量值，参数支持简写表示法。要为参数设置常量值，只需为其指定一个数字。无需在 ParticleSystemCurveMode.Constant 模式下创建 MinMaxCurve 或 MinMaxGradient 对象。

For example, instead of:
var emission = ParticleSystem.emission;
emission.rate = new ParticleSystem.MinMaxCurve(5.0f);
write:
var emission = ParticleSystem.emission;
emission.rate = 5.0f;

**性能注意事项**：在粒子模块上设置属性时，设置会立即传递到本机代码。这样可以提供最佳的性能。也就是说，在模块结构上设置属性时，不会在脚本中设置需要重新设置回粒子系统的内容；一切都是自动完成的。
