egret基础-引擎碰撞检测

新建一个HitTest类，继承 egret.DisplayObjectContainer

class HitTest extends egret.DisplayObjectContainer
{
public constructor()
{
super();
this.addEventListener(egret.Event.ADDED_TO_STAGE,this.onAddToStage,this);
}
private onAddToStage(event:egret.Event)
{
this.drawText();
var shp:egret.Shape = new egret.Shape();
shp.graphics.beginFill( 0xff0000 );
shp.graphics.drawRect( 0,0,100,100);
shp.graphics.endFill();
shp.width = 100;
shp.height = 100;
this.addChild( shp );
var isHit:boolean = shp.hitTestPoint( 100, 100 );
this.infoText.text = "isHit: " + isHit;
}
private infoText:egret.TextField;

private drawText()
{
this.infoText = new egret.TextField();
this.infoText.y = 200;
this.infoText.text = "isHit";
this.addChild( this.infoText );
}
}


调用方法在main.ts里面

var _myGrid:HitTest = new HitTest();
this.addChild( _myGrid );
