Anyone know any tutorial that teaches you how to use tile map in java without external framework or library, I need to teach the code the orthogonal camera too.
If you don’t want to use any external framework or library you’ll have to write your own TMX parser. It’s not overly complicated but I don’t know about any tutorials about this.
You basically need to pick one of the XML parsers available in Java and read the TMX Map Format reference in order to implement a parser for the different kinds of information you find in these files.
