2.Defines the variable displayed in the properties panel

  /** @prop {name:intType, tips:"整数类型示例", type:Int, default:1000}*/
    public intType: number = 1000;
  /** @prop {name:numType, tips:"数字类型示例", type:Number, default:1000}*/
    public numType: number = 1000;
  /** @prop {name:strType, tips:"字符串类型示例", type:String, default:"hello laya"}*/
    public strType: string = "hello laya";
  /** @prop {name:boolType, tips:"布尔类型示例", type:Bool, default:true}*/
    public boolType: boolean = true;
  /** @prop {name:shoe,tips:"物体",type:Node,default:null}*/
    public shoe = null; 

// 更多参数说明请访问: https://ldc2.layabox.com/doc/?nav=zh-as-2-4-0

3.Get the script to mount the object component

this.owner.getComponent(Laya.RigiBody);

4.Remove mounted scripts,Also have to remove the reference on the mount object.

5.代码发生变动,Such as adding public variables.You need to manually switch the mouse to select objects,Select it again to refresh.

6.Defined public object variablesnode There are no coordinate properties,需进行类型转换

2d:
public get gameObject():Laya.Sprite
{
    return this.owner as Laya.Sprite;
}

3d:
public get gameObject():Laya.Sprite3D
{
    return this.owner as Laya.Sprite3D;
}

-------------------------------------------------

public get transform():Laya.Transform
{
    return this.gameObject.transform;
}

7.Laya脚本参数说明

laya脚本参数

8.LayaEvent broadcasting and reception

广播事件：

Laya.stage.event("事件名");

接收事件：

onAwake()
{
    //添加监听
    Laya.stage.on("事件名",this,this.reset);
}

private reset(){
    //.....
}

onDestroy(){
    //移除监听
    Laya.stage.off("事件名",this,this.reset);
}

9.插值

Laya.MathUtill.lerp(curObj.x,targetObj.x,Laya.timer.delta/1000 * speed);

10.勾股定理 求距离

a*a + b*b = c*c;

c = Math.sqrt(a*a + b*b);

11.随机值

private getRandom(min, max) 
{
    let value = max - min;
    value = Math.random() * value;
    return value + min;
}

12.获取键盘按键

1.
onUpdate()
{
    if (Laya.KeyBoardManager.hasKeyDown(Laya.Keyboard.A)) 
    {
        this.rig.setVelocity({ x: -10, y: this.rig.linearVelocity.y });
    } else if (Laya.KeyBoardManager.hasKeyDown(Laya.Keyboard.D)) 
    {        
        this.rig.setVelocity({ x: 10, y: this.rig.linearVelocity.y });
    }
}


2.
onKeyDown(e) 
{
    //console.log(e.nativeEvent.key+".........2");
    if (e.nativeEvent.key == " " && this.canJump) 
    {
        this.canJump = false;
        this.rig.setVelocity({ x: this.rig.linearVelocity.x, y: -13 });
    }
}


3.
onKeyPress(e)
{
    console.log(e.nativeEvent.key+".........1");
    if(e.nativeEvent.key == "a")
    {
    }
}

13.The code gets the in-game object

//Find primary objects
Laya.stage.getChildByName("Player");

//Find sub-objects under this object
this.owner.getChildByName("child object name");

14.音乐音效播放

//播放音乐
Laya.soundManager.playMusic(“地址/music.mp3”,0); //0为无限循环

//Just play sound effects
Laya.SoundManager.playSound("sound/BallHit-01.mp3");
//Add an event after playback is complete
Laya.SoundManager.playSound("sound/startWistle.mp3",1,
    new Laya.Handler(this,()=>{
        Laya.stage.event("StartGame"); //广播--开始游戏
}));
