AndEngine：處理衝突折線TMX地圖

Question

我使用瓷磚的地圖，地圖TMX如何 檢查碰撞折線（） 。我檢查碰撞sucuess發展中andEngine遊戲。但折線，我不知道碰撞。 可以幫助我。

是map.tmx：

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

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

得到折線：
