Ok So the first thing we need to do is decompile minecraft so we can edit it, This is simply done.

1.) Go ahead and open your .minecraft folder
(Type %appdata% in RUN, Open the .minecraft folder )

2.) Open up your extracted MCP folder, Then open up the JARS folder.

3.) Go ahead and COPY+PASTE the bin folder and Resources from .minecraft into the Jars folder (C&P THEM)

4.) Then OPEN the Bin directory in .minecraft and COPY AND PASTE the Minecraft.jar into your jars folder .

End result should be You must login or register to view this content.

5.) Now go to the main directory in MCP and run Decompile.bat

Now go to SRC<MINECRAFT<NET<MINECRAFT<SRC< There should be 100s of Java files This is good! Now we can go onto editing them

[multipage=Step 2: Editing the Java's]
For this I will use Eclipse, Skip to the page "How to setup eclipse with MCP" to find out how .


Now I will be showing you how to edit the max meat stack size .

1.) Locate the file called ItemFood.java
2.) Double click it, You will get a small code
3.) locate

            maxStackSize = 1;

and change the one to whatever you like, as long as it is under 64!
I will use 16,

4.) Go ahead and just press CTRL+S to save it, Now you can close eclipse.
Editing is now done!!

[multipage=Step 3: Recompiling]
Go to the main directory again,

1.) Run recompile.bat
Wait for it to finish, there should be NO ERRORS.
2.) Then run Reobfuscate.bat and wait until it's done you should get something like

3.) Navigate to MCP<REOBF<MINECRAFT< There will be one class there, that is your edited mod

Now just open Minecraft.jar with your favorite program (7zip Winzip etc etc) now copy and paste the class in, delete META-INF and start minecraft.
kill a few pigs and you should notice you can stack to 16 now!!

[multipage=How to setup eclipse with MCP]

To use eclipse with MCP, just do the following steps:
- Decompile the Minecraft sources
- Open Eclipse
- Select the "eclipse" folder in MCP as workspace
- Create a mod
- You can test the modified client and server in Eclipse, debug
settings are already prepared to start the game in the IDE
- Recompile and reobfuscate as usual

[Multipage=Thanks for reading!]
Hopefully you enjoyed this tutorial, It was very basic of course and I will soon make more on more advanced stuff Until then enjoy life and minecraft

What happens if you put the number over 64?

Haven't tried it I think the limit is 64 or 111 or around that You can try it if you like though

I'll stick with Cod5 for the moment :p

Good stuff Merk, will you be expanding this tutorial to add info on creating new block types, items etc. If you need I can help with that stuff.

Ye I will be soon, just wondering, When you recompile the stuff where do i put the img's to test it? D=

It depends, are you using modloader and what image is it? I need to know a bit more about what you are trying to do first :p

Ye I was adding new tools and it said to put the tool images in the config, then when i reobfuscated it they all moved to REOBF folder with 2 classes, where do i put them?

What does your coding say to put them? You might see something like

override /terrain.png replace /yourpick.png

in which case it just goes inside the minecraft.jar

otherwise you have to add it to the images that have all the items in and then give it a special I.D.

For example, using modloader to make a block would just use the override the terrain.png so you could create an image 16x16 for your block texture and save it inside minecraft.jar.

Otherwise you would have to draw the texture inside the terrain.png and give it the correct I.D. Not too complicated once you know what you are doing. Check the official forums of minecraft for more tuts etc.

override gui/items.png /pick.png :L
