Hello, recently, I have modified Minecraft-Server1.8.jar with MCP (Minecraft Coder Pack) because I wanted to add new block to my Minecraft Server. It worked perfectly, but after that, I don't know how to use it on bukkit.jar. Because the jar (vanilla) that I reprogrammed is only a vanilla server and I want it to be a Bukkit server, like before I modified Minecraft ? How to do that correctly ? What .class files to replace in the Bukkit.jar files to make it work with my new blocks ? Thank you a lot!
