Question

我正在使用TMX地图中的Tiled地图在andEngine中开发游戏如何检查碰撞折线（）我检查与sucuess的碰撞。但折线，我不知道碰撞。可以帮助我。

是map.tmx：

<?xml version="1.0" encoding="UTF-8"?>

// --------------------碰撞---------------------

   private void createUnwalkableObjects(TMXTiledMap map){
        // Loop through the object groups
        for(final TMXObjectGroup group: this.mTMXTiledMap.getTMXObjectGroups()) {

                    final FixtureDef boxFixtureDef = PhysicsFactory.createFixtureDef(0, 0, 1f);
                    PhysicsFactory.createBoxBody(this.mPhysicsWorld, rect, BodyType.StaticBody, boxFixtureDef);
                    rect.setVisible(false);
