[LayaAir 2.0]this.scene.physicsSimulation.rayCastAll 报错

this.point.x = Laya.MouseManager.instance.mouseX;
this.point.y = Laya.MouseManager.instance.mouseY;
//产生射线
this.camera.viewportPointToRay(this.point,this.ray);

/// Laya.PhysicsSimulation.rayCast(this.ray, this.outHitResult, 30, 0)
//拿到射线碰撞的物体
this.scene.physicsSimulation.rayCastAll(this.ray,this.outHitResult);

if (this.outHitResult.succeeded)
{
//删除碰撞到的物体
this.text.text = "点击到了" + this.outHitResult.collider.owner.name ;
console.log("碰撞到物体！！")
}

上述代码运行时候报错，一直无法解决，请求大佬帮忙看一下问题？（.scene.physicsSimulation属性为灰色，不可使用）
