As many people recommended, I am using Tiled map editor to create a map for my game and it's great particularly because libgdx framework also provides with API for maps from Tiled.
I understand I can define collidable tiles or not in the map editor so I can deal with any collision in my code. But I am currently in a situation that I need to divide a tile into a collidable and non-collidable areas. Manually, I think I can define points and lines of bounds of the two areas and programmatically deal with it. But that's a lot of time-consuming work.
So I googled a lot and found this physics-body editor. This seems like a great tool to automate the process I mentioned above. The system, however, works with each of unpacked image and I am not sure it would work even if I unpack the image for its operation.
I wonder if there is any better way to do this whole process of defining collision area. Any suggestion will be much appreciated.
