前言

通过使用 DOTween 插件实现金币两段飞行效果，第一段在物体周围随机生成指定数量的金币，第二段将金币移动到指定位置。

---

一、DOTween是什么？

DoTween 是Unity的一款插件，主要用于控制物体的移动和变换。

二、使用步骤

1.导入DOTween插件

在Unity官方插件商店找到DOTween插件

https://assetstore.unity.com/packages/tools/animation/dotween-hotween-v2-27676

导入DOTween插件

启用DOTween插件

2.代码逻辑

金币飞行代码

    public class FlyControl : MonoBehaviour {private Vector3 endPos;private Vector3 startPos;private Vector3 vec1;private Vector3 vec2;[NonSerialized]public bool fly = true;public GameObject coin;//第一段位移 控制随机出现在父物体周围public void FlyCoinOne() {startPos = transform.position;float randomX = Random.Range(-50, 50);float randomY = Random.Range(-50, 50);vec1 = startPos + new Vector3(randomX, randomY, 0);coin.transform.DOMove(vec1, 0.3f).SetTarget(this);}//第二段位移 移动到指定位置public void FlyCoinTwo(Transform targetPos) {endPos = targetPos.position;vec2 = endPos;coin.transform.DOMove(vec2, 0.6f).SetTarget(this);float timer1 = 0;DOTween.To(() => timer1, x => timer1 = x, 1, 0.3f).OnStepComplete(() => { this.gameObject.GetComponent<Image>().DOFade(0, 0.3f).SetTarget(this); });float timer = 0;DOTween.To(() => timer, x => timer = x, 1, 0.61f).OnStepComplete(() => {fly = false;//Destroy(this.gameObject);});}}

控制飞行效果代码

 public class CoinEffect : MonoBehaviour{[LabelText("金币预制体")] public GameObject prefab;public Transform parent;[LabelText("金币数量")] public int num;[LabelText("最终目的地")] public Transform targetPos;[LabelText("金币飞行速度")] public float time = 1;private int childNum = 0;public bool isEnd = false;private List<FlyControl> ts = new List<FlyControl>();public void StartEffect(){for (int i = 0; i < num; i++){GameObject go = Instantiate(prefab, parent, false);go.transform.position = gameObject.transform.position;FlyControl cc = go.GetComponent<FlyControl>();if (cc != null){cc.gameObject.SetActive(true);ts.Add(cc);childNum++;}ts[i].FlyCoinOne();}}IEnumerator StartEffect1(){yield return new WaitForSeconds(0.6f);for (int i = 0; i <= ts.Count; i++){this.DOKill();yield return new WaitForSeconds(0.1f);var rm = Random.Range(0, ts.Count);yield return new WaitForSeconds(0.01f);ts[rm].FlyCoinTwo(targetPos);// ts.Remove(ts[rm]);Debug.Log(rm);i = 0;}MyLogger.PrintLog("飞行结束");}/// <summary>/// 金币飞行效果，在Update里面调用/// </summary>public void CoinEffectShow(){//第一次飞行StartEffect();//第二次飞行StartCoroutine(StartEffect1());}private void Update(){if (childNum == 0){return;}foreach (var control in ts){if (control.fly){return;}}isEnd = true;if (Input.GetKeyDown(KeyCode.R)){CoinEffectShow();}}}

3.物体配置

1.物体上装配CoinEffect脚本

2.在金币预制体上装配FlyControl脚本

三、效果展示
