I have spent 40 hours in making this tutorial. I really hope it would be useful for some of you.
“We are going to learn how to create an in game map editor that dosen’t use tiles, but directly backdrop images that you can translate, tint, rotate, scale, etc, in different parallax layers and camera zooming. You can have several tilesets and you can of course to save / load the maps using XML files. This type of editor is used in games like Braid or Aquaria. For this tutorial we are going to use IndieLib C++ 2d engine, because their entity objects are great for having graphical objects which attributes can be modified in real time. And we are going to do it with style, using graphics from lostgarden.com prototyping challenges and Aquaria game.”
