1.Drag and drop the image to the Hierarchy panel,F6执行,Not displayed in canvas

2.Public variables are defined in the script,Not displayed in the panel

3:选中物体,调整collider的x为负数时,运行时,物体消失.

4:Get object coordinates

问题5:Get the script mounted on the object through the object

问题6:Variables exposed in the properties panel After panel assignment,In-code calls appear as null 或 undefined

问题7.Note that variables with the same name cannot be used even in different scripts

问题8:如上,There is no problem getting the child objects under the script mounted object,You can't get other objects.

LayaAir脚本参数说明

1.Drag and drop the image to the Hierarchy panel,F6执行,Not displayed in canvas

Tried a few times to find out The difference between the picture that is not displayed and the picture that is displayed is. Pictures that don't show are not set to‘不打包’.Try changing the image to unpacked,结果显示正常.

2.Public variables are defined in the script,Not displayed in the 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;

Repeated research many times,最终发现问题出在layaAir IDE There is no automatic refresh mechanism,Objects not mounted by this script need to be manually selected,然后再回来,to refresh the newly defined variable properties.

very tightQ,Almost had to rewrite the blog as： LayaBoxFrom install to uninstall

3:选中物体,调整collider的x为负数时,运行时,物体消失.

It needs to be selected under the object in the hierarchy panelcollider组件,instead of selecting the object Then go to the properties panel to adjustcollider的位置.

4:Get object coordinates

NodeObjects of type have no coordinate properties,需要手动转为Laya.Sprite 或 3d的 Laya.Sprite3D

private own:Laya.Sprite = null;

this.own = this.owner as Laya.Sprite;

console.log(this.own.y);

问题5:Get the script mounted on the object through the object

Scripts are mounted on topScene物体上,can't get the object.There is no way to get the script on the object

解决办法：Don't hook scripts to scene objects,Other sub-objects can be selected,Then you can get it.

 /** @prop {name:score,tips:"物体",type:Node,default:null} */
    score = null;

private scoreScript = null;

onAwake()
{
    this.scoreScript = this.score.getComponent(ScorePanel);
}

问题6:Variables exposed in the properties panel After panel assignment,In-code calls appear as null 或 undefined

Research for a long time did not find the reason and solution,Finally, replace it with code acquisition

private txt_timer:Laya.Text =null;
private txt_myScore:Laya.Text =null;
private txt_aiScore:Laya.Text =null;

onAwake()
{
    this.txt_myScore = this.owner.getChildByName("txt_myScore") as Laya.Text;
    this.txt_aiScore = this.owner.getChildByName("txt_aiScore") as Laya.Text;                     
    this.txt_timer = this.owner.getChildByName("txt_timer") as Laya.Text;
}

问题7.Note that variables with the same name cannot be used even in different scripts

问题8:如上,There is no problem getting the child objects under the script mounted object,You can't get other objects.

 this.time_down = Laya.stage.getChildByName("txt_timeDown");

调试结果 stage 下的child数量为0. 暂未解决
