unity材质的切换

unity材质切换，主要运用射线选择物体，通过获取组建来替换材质，还有UI的调用函数。

操作：进入工程，点击物体，然后点击点击UI“yellow”“blue”“red”,点击的物体就可以切换材质

using UnityEngine;
using System.Collections;

public class ControlMaterial : MonoBehaviour {
private  GameObject objRayHit;
private Material matRayHit;
private Camera myCamera;
public Material matRed;
public Material matBlue;
public Material matYellow;

// Use this for initialization
void Start () {
myCamera = Camera.main;
}

// Update is called once per frame
void Update () {
//定义射线
Ray rays = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hits;
if (Input.GetMouseButton(0)) {
if (Physics.Raycast(rays, out hits)) {
objRayHit = hits.collider.gameObject;
//获取组件
matRayHit = hits.collider.gameObject.GetComponent<MeshRenderer>().material;
}
}
}
//定义函数，通过UI按钮调用
public void RedMaterial() {
objRayHit.GetComponent<MeshRenderer>().material = matRed;
}
public void BlueMaterial() {
objRayHit.GetComponent<MeshRenderer>().material = matBlue;
}
public void YellowMaterial()
{
objRayHit.GetComponent<MeshRenderer>().material = matYellow;
}
public void OwnMaterial()
{
objRayHit.GetComponent<MeshRenderer>().material = matRayHit;
}

}
