All of these files inside of minecraft.jar that make it run are run through a process called "obfuscation". When you add mods to Minecraft, you are taking Minecraft.jar and over-writing it with the changes needed. For example: world generation, showing blocks, managing mobs, items, and recipes. Note: You can use MCPatcher to do some or all of this work for you!Ī file on your computer called "minecraft.jar" provides everything Minecraft needs to be able to run. If you view this as a great opportunity to learn something new, then you're on the right path! You might be able to get away without knowing how to do a few of these things, but if your copy of Minecraft breaks, then you should seek help from somebody in the modding community (preferably the mod author).


That is, with each update of the Minecraft client, you will have to obtain updated mods and re-install them. Because you are doing something that is wholly unsupported by Mojang, they won't be able to help you.ĭue to how modding works, updating the Minecraft client will break your mods. Let me repeat that for you: If you mod Minecraft, you may break your copy of the game as well as any worlds that you play in. (If your copy of Minecraft is compromised, you can always backup your worlds and re-download Minecraft)
