LayaBox---背景拖动

Posted 2022-12-04 格拉格拉

刚接触laya 还不知道有没有更方便好用的拖动场景方法，就整了个 如下脚本，来实现大场景拖动。

将脚本挂载到要拖动到场景父物体上即可

export default class SceneMove extends Laya.Script 
    constructor()  super(); 
    
    private mouseX = 0;
    private minX = 0;

    private moveLeft = false;
    private moveRight = false;
    private canMove = false;

    //X移动范围
    private leftX = -300;
    private rightX = 1380;

    onMouseDown()
        this.minX = Laya.MouseManager.instance.mouseX;
    

    onMouseUp()
        this.setMoveState();
    

    onMouseMove()
        this.canMove = true;
    

    onUpdate()
        if(this.canMove==false) return;
        
        this.mouseX = Laya.MouseManager.instance.mouseX;
        if(this.mouseX>this.minX)
            if((this.owner as Laya.Panel).x<this.rightX)
            
                this.moveLeft = true;
            
        else
            if((this.owner as Laya.Panel).x>this.leftX)
            
                this.moveRight = true;
            
        

        if(this.moveLeft)
            (this.owner as Laya.Panel).x += 10;
            if((this.owner as Laya.Panel).x>=this.rightX)
                this.setMoveState();
            
        
        if(this.moveRight)
            (this.owner as Laya.Panel).x -= 10;
            if((this.owner as Laya.Panel).x<=this.leftX)
                this.setMoveState();
            
        
    

    setMoveState()
        this.canMove = false;
        this.moveLeft = false;
        this.moveRight = false;
