脚本一:用于发送消息
//挂载在所有的button父物体上
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
////// 定义button信息类
/// public class ButtonInfo{
public int id;
public GameObject obj;
}
public class ButtonTest : MonoBehaviour {
public static ButtonTest instance;
Button[] buttonArr;
//传递按钮点击的委托
public delegate void OnButtonClickDelegate(ButtonInfo info);
public event OnButtonClickDelegate OnButtonClickDel;
Button sendString; string str;
//点击按钮传递字符串的委托
public delegate void OnSendStringButtonDelegate(string str);
public event OnSendStringButtonDelegate sendstring;
void Awake() {
instance = this;
}
void Start() {
//传递String参数
sendString = GameObject.Find("Button_String").GetComponent();
sendString.onClick.AddListener(() => OnSendStringButtonClick(str));
//传递button点击事件(ButtonInfo 用来区分点击的是哪个按钮)
buttonArr = transform.GetComponentsInChildren();
for (int i = 0; i < buttonArr.Length; i++)
{
ButtonInfo info = new ButtonInfo();
info.id = i;
info.obj = buttonArr[i].gameObject;
buttonArr[i].onClick.AddListener(() => OnButtonClick(info));
}
}
// 多个按钮的点击事件
void OnButtonClick(ButtonInfo info)
{
//print(info.id);
if (OnButtonClickDel != null)
{
OnButtonClickDel(info);
}
}
// 传递字符串的点击事件
void OnSendStringButtonClick(string str) {
str = "发送消息";
if (sendstring!=null)
{

}
}
}
脚本二: 用于接收消息
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class OhterThingScripts : MonoBehaviour {
void Start () {
ButtonTest.instance.OnButtonClickDel += print;
ButtonTest.instance.OnButtonClickDel += print02;
ButtonTest.instance.sendstring += ReveiceString;
}
void print (ButtonInfo info) {
print(info.id+"————传递消息成功");
switch (info.id)
{
case 0:
print("点击了第一个按钮");
break;
case 1:
print("点击了第二个按钮");
break;
case 2:
print("点击了第三个按钮");
break;
case 3:
print("点击了第四个按钮");
break;
}
}
void print02(ButtonInfo info) {
print(info.id + "————消息重用---成功");
}
void ReveiceString(string str)
{
print(str);
}
}
