this is how you create mods http://lapissea.byethost8.com/LearnModding/ for beta? I don't know if you would be able to do it at all. I am pretty sure that you would need to deobfuscate whole mc engine or basically the whole program by hand. And after that you would have to work with really bad code and no tutorials what so ever. So yeeeah...
Rollback Post to RevisionRollBack
Not doing mc modding that much anymore because I am making a full blown game that does not have limitations that mc has. (rip Magiology for now)
I may come back if MC fixes it's rendering pipeline.
