GameObject.CreatePrimitive

参数

描述

Creates a GameObject with a primitive mesh renderer and appropriate collider.

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);
    }
}

Note: CreatePrimitive may fail at runtime. This will happen if your project does not reference the following components: MeshFilter, MeshRenderer, and BoxCollider or SphereCollider at runtime. The recommended way to avoid this crash is to declare private properties of these types. The stripping system will recognise their use and include them in the build so the components will not be deleted. A similar issue will occur if the project does not reference the Default-Material in which case the primitive object will be shown in pink to indicate the missing material.
