I am trying to add a sprite at a "grid" location on the tiled map. The TMX tiled Map is like a grid, and you can access the size of the grid by calling mTMXtiledMap.getTileRows() and mTMXtiledMap.getTileColumns().

I want to add an object at grid location, say (2, 5). My tileMap is of size (10,10).

How can I do that? There is no function like mTMXTiledMap.addChild(int x, int y, Entity mEntity).

I would appreciate any suggestions!

I am currently developing car game in AndEngine. In which I was using revolute joint for car wheel and chassis attachment. But my friend suggest me that use wheel joint for that purpose for better behavior of the car. In AndEnginen I didn't found the wheel joint implementation. So what I have to do for wheel joint implementation.

I think I have to manually update the box2d library for this purpose but I don't know how many things get updated. Please suggest me some guidance on achieving better car behavior in AndEngine.
