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对象的脚本。我想在3秒后附加脚本，更改对象上的材质并添加一个盒子对撞机。我的问题在于材料。由于对象是随机生成的，我不知道如何设置材质变量。这是我的Spawner：

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

您可以从资源

加载它

mat = Resources.Load（“myMaterial.mat”，typeof（Material））作为材料;

Answer 2

你可以像这样创建一个public static int。你的Spawner：

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;
	}
}
