unity3d 5.0 点击鼠标动态改变gameObject的material

在unity3d5.0中 renderer后面不能使用material

需要通过GetComponent来获取组件

所以代码应该这样写：

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

public class touch3d : MonoBehaviour {

Ray ray;
RaycastHit rayhit;
// Use this for initialization
void Start () {

}

void Update()
{
if (Input.GetMouseButtonUp(0))
{
int target = LayerMask.GetMask("target");
Debug.Log(target);
ray = Camera.main.ScreenPointToRay(Input.mousePosition);
if (Physics.Raycast(ray, out rayhit, 100f, target))
{
//rayhit.collider.gameObject.GetComponent<Renderer>().material.mainTexture = (Texture)Resources.Load("meinv");
rayhit.collider.gameObject.GetComponent<Renderer>().material.color = Color.blue;
Debug.Log(rayhit.collider.gameObject.name);
}
}
}
}

如果是触摸事件的话，只需要把鼠标改成触摸就行了，如下：

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
public GameObject particle;
void Update() {
if (Input.GetTouch(i).phase == TouchPhase.Began) {
int target = LayerMask.GetMask("target");
Ray ray = Camera.main.ScreenPointToRay(Input.GetTouch(i).position);
if (Physics.Raycast(ray, out rayhit, 100f, target))
rayhit.collider.gameObject.GetComponent<Renderer>().material.color = Color.blue;

}

}
}
}

Input.GetTouch(i).phase == TouchPhase.Began是判断触摸按下事件

其他的触摸事件如下：

TouchPhase Enumeration
Describes phase of a finger touch.

Values
Began   A finger touched the screen.
Moved   A finger moved on the screen.
Stationary  A finger is touching the screen but hasn't moved.
Ended   A finger was lifted from the screen. This is the final phase of a touch.
Canceled    The system cancelled tracking for the touch, as when (for example) the user puts the device to her face or more than five touches happened simultaneously. This is the final phase of a touch.
