The photon project for minecraft version 1.8. Supports all 1.8 subversions: 1.8.1, 1.8.2, etc.
I'm now working on the 1.9 version only. While the 1.8 version began to work (ie it handles player's connection, moves and very basic chunk generation), I won't use it as a base for the 1.9 version. I'll do a proper work instead: one API, one implementation. And the API will be independant from the implementation. Photon will also get a new (much better) architecture.
The 1.8 discontinued version had no API, and does NOT implement the 1.9 API in any way
If you still want to try this discontinued version, you'll see that some dependancies are missing. To fix the problem, download my JSON library, version 1.1 and add it to the classpath.
