TooManyItems Minecraft Cheats Mod
TooManyItems is basically an in game memory editor. It was made by Marglyph and all credit goes to them for making our lives easier.
It’s a single player only cheat for the most part. It does work if you have OP status on a server but that’s not really a cheat, it just saves you from typing in commands.
There’s not really too much to explain. Once installed anytime you open your inventory you get this instead of just your normal inventory options.
You have access to the items you want on the right which you can place straight into your inventory. The menu on the left lets you save and load inventory states and there’s a trash on the bottom left so you can easily delete items you no longer need.
Full installation instructions and download links can be found on the TooManyItems forum thread: http://www.minecraftforum.net/topic/140684-173-toomanyitems-in-game-invedit-july-1/
That’s your basic single player item cheat, for the more fun stuff such as flying etc… you need to use a client mod made for the purpose. Note that other private ones do exist and have a lot of features you won’t see here – but these are ones you can use right away for free. It’s pretty easy to install but I’ll include a quick video here which can help guide you through it.
