AS3顯示列表和box2d

Question

我從子類擴展了一個名為createBrick的子類中的一個名為“ brick”的函數，並且在導出用於運行時共享的庫中創建了一個名為“ Brick”的影片剪輯。 出於某些奇怪的原因，即使我在調試代碼時就創建了磚，也無法在舞台上顯示該磚。

這是功能

     public  class createBrick extends Sprite {

        public function createBrick(_main:Main) {
                    main = _main; 
                    var go:Brick = new Brick();
                    addChild(go);
                    trace(go.x);
                    brick(475, 235, 30, 30);
        }

    private function brick(pX: int, pY: int, w: Number, h: Number): void {

                var bric:Brick = new Brick();
                addChild(bric);
                bric.x = pX;
                bric.y = pY;
                bric.width = w;
                bric.height = h;

                var polygonShape: b2PolygonShape = new b2PolygonShape();
                var polygonFixture: b2FixtureDef = new b2FixtureDef();
                polygonShape.SetAsBox(w / 2 / worldScale, h / 2 / worldScale);
                polygonFixture.shape = polygonShape;
                polygonFixture.density = .2;
                polygonFixture.restitution = 0.9;
                polygonFixture.friction = 0.9;
                var brickbodyDef: b2BodyDef = new b2BodyDef();
                brickbodyDef.type=b2Body.b2_dynamicBody;
                brickbodyDef.userData = bric;
                brickbodyDef.position.Set(bric.x / worldScale, bric.y / worldScale);
                var theBrick: b2Body = world.CreateBody(brickbodyDef);
                theBrick.CreateFixture(polygonFixture);
                }
        }

如果我在主文檔類中擁有所有代碼，並且在舞台上確實看到了一塊磚，則該功能可以完美地工作。 有什么提示我引用不正確嗎？

我想通了，只需要通過主文檔類的階段引用就可以顯示精靈。
