人物的半透明效果

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    void Update() {
        RaycastHit[] hits;
        hits = Physics.RaycastAll(transform.position, transform.forward, 100.0F);
        int i = 0;
        while (i < hits.Length) {
            RaycastHit hit = hits[i];
            Renderer renderer = hit.collider.renderer;
            if (renderer) {
                renderer.material.shader = Shader.Find("Transparent/Diffuse");
                renderer.material.color.a = 0.3F;
            }
            i++;
        }
    }
}
