Description
Script interface for Particle Systems.
A powerful and versatile Particle System component.
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。
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:
ParticleSystem.emission.rate = new ParticleSystem.MinMaxCurve(5.0f);
write:
ParticleSystem.emission.rate = 5.0f;
Performance note: When setting properties on particle modules, the settings are passed immediately into native code. This gives the best performance. This means that setting properties on a module struct doesn't set something in script that requires setting back to the Particle System; it all happens automatically.
