Unity 模拟系统提示功能,制作提示框定时消失,不同类型的提示效果

Unity 提示功能

效果:

分析:

• 这里用到了对象池,时间一到便要回收提示框,再次使用要置顶显示内容
• 每个提示框都可以修改颜色,内容,存在的时间等信息
• Scroll View能够根据内容的多少进行自适应高度

代码:

测试代码

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

public class HintTest : MonoBehaviour
{
    
    
    public MessageManager messageManager;
    public bool test1 = false;
    public bool test2 = false;
    public bool test3 = false;
    public bool test4 = false;
    void Start()
    {
    
    
        messageManager.ShowMassameContents("3", "测试开始时提示信息,显示时间10s", 10);
    }
    int index = 0;
    // Update is called once per frame
    void Update()
    {
    
    
    	//测试不同类型
        if (test1)
        {
    
    
            test1 = false;
            messageManager.ShowMassameContents("1", "提示信息"+ index + ",显示时间5s", 5);
            index++;
        }
        if (test2)
        {
    
    
            test2 = false;
            messageManager.ShowMassameContents("2", "提示信息" + index + ",显示时间5s", 5);
            index++;
        }
        if (test3)
        {
    
    
            test3 = false;
            messageManager.ShowMassameContents("3", "提示信息" + index + ",显示时间5s", 5);
            index++;
        }
        if (test4)
        {
    
    
            test4 = false;
            messageManager.ShowMassameContents("4", "提示信息" + index + ",显示时间5s", 5);
            index++;
        }
    }
}

其他:

发现一个可以利用Unity自身功能制作一个自适应文字内容的边框,原理非常简单,限制子物体的大小,再根据子物体限制自身大小

效果:
