cocos creator3.7版本拖拽事件处理

前言：网上能找到的资料都太落后了，导致哥们用AI去写，全是瞎B写，版本都不对。贴点实际有用的。别老捣鼓你那破convertToNodeSpaceAR或者convertToNodeSpace了。

核心代码

touch.getDeltaX()
touch.getDeltaY()
在这里插入图片描述

在cocoscreator3.7版本中通过这个方法，修改节点坐标就可以了。

import { _decorator, Button, Component, EventTouch, Node, systemEvent, UITransform, Vec2, Vec3 } from 'cc';
const { ccclass, property } = _decorator;@ccclass('LockManager')
export class LockManager extends Component {@property(Node)public dragNode: Node = null; // 假设这是您想要拖拽的 Sprite 所在的节点@property(Node)public transformNode: Node = null; // 假设这是您想要移动的node节点private _isDragging = false;start() {if (this.dragNode) {this.dragNode.on(Node.EventType.TOUCH_START, this.onTouchStart, this);this.dragNode.on(Node.EventType.TOUCH_MOVE, this.onTouchMove, this);this.dragNode.on(Node.EventType.TOUCH_END, this.onTouchEnd, this);this.dragNode.on(Node.EventType.TOUCH_CANCEL, this.onTouchCancel, this);}}onTouchStart(touch: EventTouch) {this._isDragging = true;}onTouchMove(touch: EventTouch) {if (!this._isDragging) return;// 更新节点的y坐标const originPos = this.transformNode.getPosition()originPos.y += touch.getDeltaY();this.transformNode.setPosition(originPos)}onTouchEnd(touch: EventTouch) {this._isDragging = false;// 可以在这里添加拖拽结束后的逻辑}onTouchCancel(touch: EventTouch) {this._isDragging = false;// 可以在这里添加触摸被取消的逻辑}onDestroy() {if (this.dragNode) {this.dragNode.off(Node.EventType.TOUCH_START, this.onTouchStart, this);this.dragNode.off(Node.EventType.TOUCH_MOVE, this.onTouchMove, this);this.dragNode.off(Node.EventType.TOUCH_END, this.onTouchEnd, this);this.dragNode.off(Node.EventType.TOUCH_CANCEL, this.onTouchCancel, this);}}
}
