Unity中实现伤害飘字或者提示飘字效果（DoTween实现版本）

news2024/11/6 17:40:55

！！！在实现以下效果之前，一定要往项目中导入DoTween插件。

一、搭建测试场景

1、在场景中新建一个带有Text组件的游戏物体A，并把这个游戏物体A中Text组件的Color属性中alpha值为0，让文字在场景中隐藏。
在这里插入图片描述

二、编写测试脚本

1、在项目中新建一个名为Test的测试脚本，并把以下代码复制到Test脚本中。

using DG.Tweening;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class Test : MonoBehaviour
{
    public Text text_piaozi;
    GameObject go;
    Sequence mySequence;

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            FlyTo();
        }
    }

    public void FlyTo()
    {
        if (go != null)
        {
            Destroy(go?.gameObject);
            // 取消序列  
            if (mySequence != null && mySequence.IsActive())
            {
                mySequence.Kill();
                Debug.Log("Sequence has been killed.");
            }
        }
        go = GameObject.Instantiate(text_piaozi.gameObject, text_piaozi.transform.parent);
        Debug.Log(go);
        Graphic graphic = go.GetComponent<Text>();
        RectTransform rt = graphic.rectTransform;
        Color c = graphic.color;
        c.a = 0;
        graphic.color = c;
        mySequence = DOTween.Sequence();
        Tweener move1 = rt.DOMoveY(rt.position.y + 50, 0.5f);
        Tweener move2 = rt.DOMoveY(rt.position.y + 100, 0.5f);
        Tweener alpha1 = graphic.DOColor(new Color(c.r, c.g, c.b, 1), 0.5f);
        Tweener alpha2 = graphic.DOColor(new Color(c.r, c.g, c.b, 0), 0.5f);
        mySequence.Append(move1);
        mySequence.Join(alpha1);
        mySequence.AppendInterval(1);
        mySequence.Append(move2);
        mySequence.Join(alpha2);
        mySequence.OnComplete(() => { Destroy(graphic.gameObject); });
    }
}
