A introduction to hacking clients.

[Bandit The Script Kiddie]

How to make your first hacked client, the bandits way.
NOTE - This is for windows. I will make a mac tutorial later on.
-----------------------------------------------------------------------
This includes:
-how to setup mine craft code(r) pack(mcp)
-how to setup eclipse
-how to setup your hack
-how to create your first hack
-how to use your hack
-----------------------------------------------------------------------
Setting up mine craft code(r) pack(mcp):

1-Download mcp from the mcp wiki
NOTE - due to no outside linking, I cannot link where to get it.

2-When you finish downloading it, You should get a screen that shows all the files. The ones your going to mostly focus on are
-cleanup.bat / cleanup.sh
-decompile.bat / decompile.sh
-reobfuscate.bat / reobfuscate.sh
-updatemcp.bat / updatemcp.sh

3-Transport the files to a folder you choose. I named mine, "SimpleCraft".

4-Now get a clean install of the bin folder and the resource folder and drag them into "jars".
-To get there, do %appdata% and go to the .minecraft folder and simply copy the bin and resources folder.

5-Once you have finished that. Run updatemcp.bat to make sure mcp is fully updated.

6-Now, Run decompile.bat. Answer "Yes" To everything.
-You will get a server jar error. Do not worry about this because you are making a client, not a server mod.

7-Now you are ready to get eclipse up and running.
-----------------------------------------------------------------------
Setting up eclipse

1-Download eclipse
NOTE- I cannot post external links so you will have to google for it

2-Now put it anywhere you like and run it.

3-When it asks for workplace put it to:
(/<foldername>/eclipse)
Example
/SimpleCraft/eclipse

4-Your done, Now let it load and your set to make your first hack
-----------------------------------------------------------------------
Setting up your hack

1-Make your way to GUIingame, You should see a code right in the beginning, after the package code. You should see this code:

import java.aw*****lor;
import java.util.ArrayList;
import java.util.Random;
import net.minecraft.client.Minecraft;
import org.lwjgl.opengl.GL11;

Now you would want to enter this:

import java.aw*****lor;
import org.lwjgl.input.Keyboard;
import java.util.ArrayList;
import java.util.Random;
import net.minecraft.client.Minecraft;
import org.lwjgl.opengl.GL11;

What this does is just make a interface.

2-Scroll down to:

public class GUIingame extends GUI

Now just press enter and enter this

private boolean keyStates[];

This means we have done a way for it to be true or false.

3-Scroll down further til you see a bunch of codes that say fontRenderer and gl11 pop matrix (Something around those lines)
Then your ready to make a "watermark". To do this, Make a "else" statement then put in the code.

{else
drawStringWithShadow("SimpleCraft", 2, 12, 0xffffff);

Now, The 1st number(2) means the x location, and the 2nd number(12) means y location. 0xffffff is the color.

4-Now what we want to do is make a new class file. To do this just right click on any class file and click "New" then class file. Next you want to write what the name is. I will name it hacks. Now once we get into the code, It should look like this

import net.minecraft.src;

public class hacks{

}

Now what you want to do is add a new static boolean. To do this just write

static boolean fullbright;

I am using full bright as a example. You can change this to any name you want. After that it should look like this

import net.minecraft.src;

public hacks{

static boolean fullbright;
}

5-Next we want to do is under where we wrote the fontRenderer code, write this

if(checkKeyboard(KEY_C))
{
hacks.fullbright = !hacks.fullbright;
mc.renderGlobal.loadRenderers();
}

Now what this does is just say what key you need to press for it to work and the mc.render part just forces a render. Now what were doing now is the actual code.

6-The actual code part. The first thing were going todo is go to GUIingame and then were going to make a word on the screen that shows if full bright is on or off.

if(hacks.fullbright)
{
fontrenderer.drawStringWithShadow("FullBright = ON", 2, 24, 0xfffff);
}else
fontrenderer.drawStringWithShadow("FullBright = OFF", 2, 24, 0xfffff);

Next thing were going to do is go to block.java and search for brightness till you get something like this.

float getBlockBrightness(IBlockAccess iblockaccess, int i, int j, int k)
{
return iblockaccess.getBrightness(i, j, k, lightValue[blockID]);
}

Then were going to make a if statement.

float getBlockBrightness(IBlockAccess iblockaccess, int i, int j, int k)
{
if(hacks.fullbright)
{
return 1000F;
}else
return iblockaccess.getBrightness(i, j, k, lightValue[blockID]);
}

Next were going to do the same thing but remove the F to the lower part of the code. The part where it gets the MixedBrightness For the block.

{
if(hacks.fullbright)
{
return 1000;
}else
return iblockaccess.getBrightness(i, j, k, lightValue[blockID]);
}

Now that your done with the code, Press the Green Arrow on top of eclipse to launch mine craft and test it. Now I will teach you how to get the class file and insert it to your mine craft.
-------------------------------------------------------------------
Getting the class file.

All you have to do is run the file called reobfuscate.bat and go into the folder called reobf once you are done running the file.

This has been my first post / thread and I done this all out of memory to help you all who are having trouble. If you guys get errors please post them on this thread and I will do my best to fix them. (Probably just careless mistakes I did if I did any.) If I helped you, Press the thanks button.

[link491]

alright, this is great, i love this because i want to learn java, but every time i try this, i get an error with the line
}else
fontrenderer.drawStringWithShadow("Combustible v0.1", 2, 2, 0xffff00);
if(checkKeyboard(KEY_F))
{

it says that KEY_F can not be resolved as a variable! Please help

[f2pc4e]

thx, will try that on later

[vinnii]

You must change frontrender to var8

[LordPankake]

Some of these methods are a bit-outdated and could be done more efficiently.
For people new to coding though, this explains it pretty nicely.

[GiveMeForceOPNigger]

I got stuck at the part where you insert potato.What do I do from there?

[LordPankake]

if(checkKeyboard(KEY_F))

if (checkKey(Keyboard.KEY_F))
{
 //stuff from tut here
}

you forgot your "Keyboard." before the KEY_F.
