// Create a plane, sphere and cube in the Scene.

__注意：[__.CreatePrimitive](https://docs.unity.cn/cn/current/ScriptReference/__.CreatePrimitive.html) 在运行时可能失败。发生此问题的原因是 您的项目在运行时未引用以下组件：[MeshFilter](https://docs.unity.cn/cn/current/ScriptReference/MeshFilter.html)、[MeshRenderer](https://docs.unity.cn/cn/current/ScriptReference/MeshRenderer.html) 和 [BoxCollider](https://docs.unity.cn/cn/current/ScriptReference/BoxCollider.html) 或 [SphereCollider](https://docs.unity.cn/cn/current/ScriptReference/SphereCollider.html)。避免此崩溃的建议方式是 声明这些类型的私有属性。此剥离系统 将识别它们的用途，这会将它们包含在此版本中，这样便不会删除这些 组件。
