Hi!
I want to share this information.
I hope it’s very helpful xD
If you do not have the application can download from here: http://www.mapeditor.org/
- Open Tiled. File->New (view image: tiled_00.png)
- Map->New set of patterns. Search the image: Grass_Tiles_NSMBU.png
- Add a new layer objects. Write “objetos”. (view image: tiled_01.png)
- Define our rectangular objects. (view image: tiled_02.png and tiled_03.png)
- Save our projecy with testCocos2dx.tmx.
