【小松教你手游开发】【unity实用技能】unity 几种触发事件

1.在button上挂Box Collider,勾上Is Trigger.添加UIButtonMessage，设置Target和FunctionName。

2,.在button上挂Box Collider,用在GameObject上挂UIEventListener，再写个脚本获取并处理事件如：

using UnityEngine;  
using System.Collections;  
  
public class PlayerRotateEventHandler : MonoBehaviour {  
  
    private GameObject pc_raymond_01;  
    private bool isPressed = false;  
    public float scaleRotate = 1.0f;  
    void Awake()  
    {  
        //  
    }  
    // Use this for initialization  
    void Start () {  
        //pc_raymond_01 = GameObject.Find("UI_3DCharacter/04/pc_dohee");  
        UIEventListener.Get(gameObject).onDrag = OnCharacterDrag;  
        UIEventListener.Get(gameObject).onPress = OnCharacterPress;  
      
    }  
      
    // Update is called once per frame  
    void Update ()
	{   
    }  
  
    void OnCharacterDrag(GameObject obj, Vector2 delta)  
    {  
    }  
  
    void OnCharacterPress(GameObject obj, bool pressed)  
    {  
        isPressed = pressed;  
    }  
}  

3.在button上挂Box Collider,在GameObject上的脚本的Update()函数上，判断if (Input.GetMouseButtonDown(0) )，if (Input.GetMouseButtonUp(0))
