xASjpg

if you already set up MCP then skip to step #13 and run eclipse

  1. download required files (if you have already done that skip to step #2)
    make sure you download the current file. for eclipse, get the classic version


  2. extract MCP into a FOLDER on your desktop

  3. open the MCP folder

  4. open jars folder

  5. open you .minecraft folder (on windows click start, accessories, run, type in %appdata%)

  6. copy bin and resource folders into jar folder (in MCP)

  7. open the bin folder (the one that's in the MCP)( also you can close out your .minecraft folder)

  8. right click on minecraft.jar and (if your using 7zip, click open archive)

  9. right click on your ModLoader.zip and do the same as in step #8 and open archive

  10. drag everything from the ModLoader.zip into your minecraft.jar (DO NOT DELETE META-INF!!!!!)

  11. close minecraft.jar and modloader.zip + in the root of the MCP folder run decompile.bat


  12. during the decompile process you should get an error that has Render in it, that's ok. if you did not get that you did somthing wrong.


  13. once it finishes run your eclipse.exe and select your workspace as the eclipse folder in the root of your MCP


  14. once its loaded on your eclipse client, open the client folder in the package explorer, then open the src, then
    net.minecraft.src, then right click net.minecraft.src and select New -> Class


  15. base mod names must be named with mod_ (e.x. mod_MyNewMod )


  16. add abstract right after public so you get public abstract class mod_MyNewMod and add extends BaseMod after your mod name.


  17. then add this inside of the brackets (everything goes inside those brackets you see when you make a new class):



    public mod_MyNewMod()
    {

    }
    public void load()
    {

    }
    public String getVersion()
    {
    return "MyNewMod 1.2.5";
    }

  18. in the public void load() add this:

    ModLoader.addRecipe(new ItemStack(Block.sponge, 1), new Object[]
    {
    "XXX", "TBT", "XXX", 'X', Block.sand, 'T', Item.clay, 'B', Item.bucketEmpty
    });

    the " 1 " after block.sponge is how many you get out of crafting
    the "XXX" is the top row, the "TBT" is the middle row, and the last one is the last row
    the 'X', Block.sand tells what the X means in the crafting recipe (same thing for the others)


  19. save your class file and go back to your MCP folder


  20. run recompile.bat (if you get an error you did something wrong)


  21. if you get no errors then run startclient.bat


  22. test out your new crafting recipe


  23. on MCP click the conf folder


  24. open the client.txt


  25. delete EVERYTHING there


  26. save the file


  27. in the root of MCP run Rebustfocate


  28. after it is done your mod files will be in the rebof folder


  29. Guess what? Your done with your first mod! Congrats!
if you want you can go on to the 2nd tutorial now!

It didn't work.... where in the jars folder should I put it? Does it have to be a .jar file? Can't it be a .exe file?
