(If your copy of Minecraft is compromised, you can always backup your worlds and re-download Minecraft) If you mod Minecraft, you may break your copy of the game as well as any worlds that you play in.

Because you are doing something that is wholly unsupported by Mojang, they won't be able to help you. Due to how modding works, updating the Minecraft client will break your mods. That is, with each update of the Minecraft client, you will have to obtain updated mods and re-install them. However, the worlds you created will not be destroyed (although any mod items in your world will not be present). Additionally, the authors of the mod make no guarantees as to whether or not the code works, much less any guarantees of support.

Nearly all mod packs have auto-installers that make adding mods to Minecraft extremely easy for the beginner Modder. You can search for mod packs on the Mods page. Prerequisites [ ] You should always know the prerequisites first, else the whole mod might not work. Here is a list of prerequisites you must have: • Knowledge of zipping/unzipping files, and working with a good archive utility (such as,, etc.). • Knowing how to accurately read and follow instructions. • Knowing how to submit proper bug reports.

Mar 27, 2017 Try out your new mod. After installing the mod, you can load it up in Minecraft to test and use it. Open the Minecraft Launcher.

If you view this as a great opportunity to learn something new, then you're on the right path!

Note: You can use or MCPatcher to do some or all of this work for you! How Mods Work [ ] A.jar file on the versions folder under provides everything Minecraft needs to be able to run.

When you add mods to Minecraft, you are taking the.jar file and over-writing it with the changes needed. All of these files inside run through a process called.

Furthermore, everything in the game (,,, etc.) has an ID which allows the game to differentiate each of them. As new content is added to Minecraft, new IDs are used. Notes • This is fundamentally changing the way Minecraft was meant to be played. So Mojang will not be able to help you in any way, and are not responsible for crashes, data loss, etc. • Some mods might claim to do something, but could in fact have been authored with a malicious intent such as stealing your Minecraft username/password, or install a keylogger. This is only a concern if: • The mod that you download contains an executable and you run it. • The mod that you download informs you that you should modify the If the mod that you wish to install involves neither of these actions then you should feel quite secure.

If not, a good measure of safety is to only install mods from a secure and safe website. Make sure to read the comments on mod posts before downloading and installing. • When Minecraft is updated, all mods need to be re-updated by their authors and re-downloaded and placed into the folder, because the launcher downloads a legit copy of Minecraft from Mojang when it updates. If a mod uses an ID number that Mojang uses in the update, this will cause further issues, and your world might look weird, or potentially be completely broken and unusable. Mod authors do this of their own free will, and it can take weeks for them to update.

However, this doesn't mean you should harass the author about it. • If two mods do similar things, they will likely be incompatible, because they will both try to change the same thing (this can be fixed; nowadays, mods come with a properties file to change block and item IDs to fix conflicts) • You may be adding new entities to your worlds, so if you ever have to remove the mods (say because of a Minecraft update), that world will no longer be compatible. Downloading Mods [ ] Always be careful when downloading mods. Make sure you download them from the original source to minimize the risk of viruses and be careful with running anything you download on your computer. Custom Mods [ ] ModLoader, Spawnlist and friends [ ] There are many mods that absolutely require other mods to work, because they use some of the commands these other mods give.

These are known as utility mods. These include (for adding mods in general), and, which is a more advanced ModLoader.

These mods that are required by some mods will need to be installed with the mod before Minecraft is run. Without them, the mod will not work and can even lead to Minecraft crashing. A much more list of mods can be found. Mod authors may give a configuration file to change item IDs.

Find the conflicting ID, and change it. Just remember that when an update for Minecraft or the mod comes out, you must use the same item IDs, else the game will crash. Making Backups [ ] If you want to test a mod without any risk, simply backup. Restoring it will revert everything to a pre-modded state (including your worlds). If you are going to mod in a more persistent and complex fashion then you should keep the following in mind: • Back up your worlds at.minecraft/saves • If you've had previous mods installed, back up the.jar file too, so as not accidentally uninstall mods.

• If you wish to potentially keep your stats and achievements safe, backup the directory.minecraft/stats • Do not put custom mod only items in chests if you wish to access that world again from an unmodified version of Minecraft. It is possible that if you do so, when you remove the mod and then try to open or break the chest, Minecraft might crash. If you do this accidentally, you can stand on top of the chest, and type in / ~ ~-1 ~ air. It will remove the chest and the items inside it without crashing the game. Backing up your worlds should be done every time you install a new mod.
