根据自己的需求修改为如下代码
使用过程中出现拖动ui位置错误的情况修改为使用 localPosition 但是吸附到指定位置却需要用的position public class DragAndDrop : MonoBehaviour, IBeginDragHandler, IDragHandler, IEndDragHandler{private RectTransform dragTransform;private Vector2 initPosition;private Vector2 startPosition;[Header(正确区域)]public RectTransform targetArea;[Header(初始区域)]public RectTransform originalArea;[Header(错误区域)]public RectTransform[] targetOtherArea;private bool result; //拖动结果private bool valid; //拖动有效public bool Result { get result; private set result value; }public bool Valid { get valid; private set valid value; }public void Awake(){dragTransform GetComponentRectTransform();//初始位置initPosition dragTransform.localPosition;}/// summary/// 重置位置/// /summarypublic void ResetPos(){dragTransform.localPosition initPosition;result false;valid false;}public void OnBeginDrag(PointerEventData eventData){//开始拖动的位置startPosition dragTransform.localPosition;//设置UI最后渲染dragTransform.SetAsLastSibling();}public void OnDrag(PointerEventData eventData){dragTransform.localPosition GetLocalPosition(eventData.position);}public void OnEndDrag(PointerEventData eventData){result RectTransformUtility.RectangleContainsScreenPoint(targetArea, eventData.position);
#if UNITY_EDITORDebug.Log($拖动结果: {result});
#endifif (result){//吸附到目标位置dragTransform.position targetArea.position;valid true;return;}else{foreach (var item in targetOtherArea){if (RectTransformUtility.RectangleContainsScreenPoint(item, eventData.position)){//吸附到目标位置dragTransform.position item.position;valid true;return;}}//原始位置,拖动无效if (RectTransformUtility.RectangleContainsScreenPoint(originalArea, eventData.position)){//吸附到目标位置dragTransform.position originalArea.position;valid false;return;}}//其它情况还原为开始拖动的位置valid false;dragTransform.localPosition startPosition;}private Vector2 GetLocalPosition(Vector2 screenPosition){Vector2 localPosition Vector2.zero;RectTransformUtility.ScreenPointToLocalPointInRectangle(dragTransform.parent as RectTransform, screenPosition, null, out localPosition);return localPosition;}}Demo
using MyTool.Tools;
using UnityEngine;
using UnityEngine.UI;public class Demo : MonoBehaviour
{public DragAndDrop dragAndDrop;public Button okBtn;// Start is called before the first frame updatevoid Start(){okBtn.onClick.AddListener(OnClickOkBtn);}private void Update(){okBtn.interactable dragAndDrop.Valid;}void OnClickOkBtn(){if (dragAndDrop.Result){Debug.Log(恭喜你答对了);}else{Debug.Log(很遗憾没有答对);}}
}
ui搭建 效果
