Unity 3d 错误 CS0246：找不到类型或命名空间名称“ParticleEmitter”

Question

“Assets\ParticleScaler\ParticleScaler.cs(99,12)：错误 CS0246：找不到类型或命名空间名称‘ParticleEmitter’（是否缺少 using 指令或程序集引用？）”

我到处寻找这个问题。 我在 stackoverflow 中找到了一些答案，一些类似的错误，我做了他们所说的一切，但它们不起作用。任何时候我尝试一个答案都会得到与我再次定义的名称相同的错误。 几天来我一直在寻找答案，但没有答案。如果你帮我解决这个问题，我将非常感激。 谢谢

用 ParticleSystem 替换 ParticleEmitter，因为 ParticleEmitter 已过时。 这对我有用。
