Android GDX Box2D 三角形

Question

我需要 Box2D GDX And​​roid 的三角形定义。我会把宽度除以 3 还是有一个类？这是普通矩形的代码:

            _rect1 = CCSprite.sprite("RectWood.png");
            _rect1.setPosition(CGPoint.make(-10, -10));
            this.addChild(_rect1);
            //Create box
            BodyDef Box1BodyDef = new BodyDef();
            Box1BodyDef.type = BodyType.DynamicBody;
            Box1BodyDef.position.set(350/PTM_RATIO, 80/PTM_RATIO);

            // The body is also added to the world.
            Body Box1Body = _world.createBody(Box1BodyDef);
            Box1Body.setUserData(_rect1);

            // Define the shape.
            PolygonShape Box1Box = new PolygonShape();


            Box1Box.setAsBox(10/PTM_RATIO, 50/PTM_RATIO);
            Box1Body.createFixture(Box1Box,1.5f);

:) 谢谢，乔

只需将 3 个顶点添加到您的 Box1Box 对象，而不是调用 setAsBox()。
