Unity - 添加 Material 到游戏对象

Question

我正在尝试创建一个连续生成对象并将脚本附加到所有生成的对象的脚本。我希望附加脚本在 3 秒后更改对象上的 material 并添加一个盒子碰撞器。我的问题是 material。由于该对象是随机生成的，所以我不知道如何设置 material 变量。这是我的生成器：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Spawner : MonoBehaviour {
    //Variables
    public float x_max;
    public float x_min;
    public float y_max;
    public float y_min;
    private float Size;
    public float s_max;
    public float s_min;
    public float w_max;
    public float w_min;
    private float ProceduralCacheSize;
    private GameObject sphere;
    private float waitTime = 5f;
    private int fix;

    // Use this for initialization
    void Start () {
        Spawn ();
        Spawn ();
        Spawn ();
        StartCoroutine("MyCoroutine");
    }

    // Update is called once per frame
    void Update () {

    }
    void Spawn(){
            Size = Random.Range (s_min, s_max);
            sphere = GameObject.CreatePrimitive (PrimitiveType.Sphere);
            sphere.transform.position = new Vector3 (Random.Range (x_min, x_max), Random.Range (y_min, y_max), 0);
            sphere.transform.localScale = new Vector3 (Size, Size, Size);
            var fbs = sphere.AddComponent<Astroid> ();
        }

    IEnumerator MyCoroutine(){
        StartCoroutine("Change");
        waitTime = Random.Range (w_min, w_max);
        yield return new WaitForSeconds(waitTime);
        StartCoroutine("MyCoroutine");
        StartCoroutine("Change");
        Spawn ();
    }
}

这是附加的脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Astroid : MonoBehaviour {
    //I need to be able to set this variable to a material
    public Material mat;
    // Use this for initialization
    void Start () {
        this.GetComponent<SphereCollider>().enabled = false;
        StartCoroutine("Change");
    }
    // Update is called once per frame
    void Update () {

    }
    IEnumerator Change(){
        yield return new WaitForSeconds (3);
        this.GetComponent<SphereCollider>().enabled = true;
        this.GetComponent<Renderer> ().material = mat;
    }
}

Answer 1

您可以直接从资源中加载它

mat = Resources.Load("myMaterial.mat", typeof(Material)) as Material;

Answer 2

你可以像这样创建一个 public static int。你的生成器：

public Material mat;
public static Material mat2;
void Start(){
mat2 = mat;
}

在你的 astroid 脚本中：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Astroid : MonoBehaviour {
 //I need to be able to set this variable to a material
 //public Material mat;
 // Use this for initialization
 void Start () {
  this.GetComponent<SphereCollider>().enabled = false;
  StartCoroutine("Change");
 }
 // Update is called once per frame
 void Update () {
  
 }
 IEnumerator Change(){
  yield return new WaitForSeconds (3);
  this.GetComponent<SphereCollider>().enabled = true;
  this.GetComponent<Renderer> ().material = Spawner.mat2;
 }
}
