The Brown family has had just tons and tons of odd difficulties in doing
something that supposedly everyone is doing: Adding mods into the minecraft
So here is a step by guide of the method I found that works for me.
For this walkthrough, I will specifically detail how I got the "TooManyItems"
mod to work.
(Found at http://www.games-utilities.com/toomanyitems-mod-for-minecraft-1-4-5/)
Note also, that I have just written a java utility to make the process more point-and-click: --)) modder (((---
Note also, that this is a guide for how to do things by typing at a command prompt. So, on the down side, there's less pointy-clicky. On the plus side, you should actually be able to copy-and-paste instructions here!!
cd "/Users/$USER/Library/Application Support/minecraft/bin"OB
cp minecraft.jar minecraft.jar.origHowever, if you have already added some mods, you will probably want to change it to someting like "minecraft.jar.modded"
mkdir moddir cd moddir jar xf ../minecraft.jar
jar xf ~/Downloads/TooManyItems*
rm -r META_INF jar cf ../minecraft.jar *And that's it! You should now be able to start up minecraft with your added mod. If it doesnt work... don't panic, just copy back the file you saved, in step 1. You DID follow all the steps, right?
It's also beneficial to keep around the original, "pure" minecraft file, as mentioned, because some mods allegedly conflict with others. So in that case, you can extract from the original file, rather than a heavily modded one, and make a special new minecraft.jar for some non-cooperative mod.
At some point, I may write a java program to make this process more pointy-clicky. I'm actually halfway done with it. Feel free to send me an email if you dont see it after april 2013!
