public static [GameObject](https://docs.unity.cn/cn/current/ScriptReference/GameObject.html) CreatePrimitive ([PrimitiveType](https://docs.unity.cn/cn/current/ScriptReference/PrimitiveType.html) type);

## 参数

type

要创建的原始对象的类型。

## 描述

``` cs
using UnityEngine;

public class Example : MonoBehaviour
{
    // Create a plane, sphere and cube in the Scene.

    void Start()
    {
        GameObject plane  = GameObject.CreatePrimitive(PrimitiveType.Plane);

        GameObject cube = GameObject.CreatePrimitive(PrimitiveType.Cube);
        cube.transform.position = new Vector3(0, 0.5f, 0);

        GameObject sphere = GameObject.CreatePrimitive(PrimitiveType.Sphere);
        sphere.transform.position = new Vector3(0, 1.5f, 0);

        GameObject capsule = GameObject.CreatePrimitive(PrimitiveType.Capsule);
        capsule.transform.position = new Vector3(2, 1, 0);

        GameObject cylinder = GameObject.CreatePrimitive(PrimitiveType.Cylinder);
        cylinder.transform.position = new Vector3(-2, 1, 0);
    }
}

__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。
