Nice tutorial. I found this as an outline of the process because some things are different for Mac. For Mac specific things I have to Google stuff xD

I Mean you could make some great youtube tutorial videos about how to start coding etc..

But why did you chose to show your skills, here on hypixel?

If You Want to work as a developer here at hypixel, just send a email and show them what can you do...

Hey Guys, it's me! :^)

Today I will try to teach you on how to start coding chat based mods.

Disclaimer: I am not an professional coder! I learned this all by myself from watching tutorials on YouTube.
Disclaimer: I will be using Eclipse for this tutorial.

Experience with C# or Java is nice to have
It might get really complicated.

So let's begin!

[EDIT:]
Step 0.
Install Java JDK and at Java_Home to your system variables. Tutorial here: "
https://confluence.atlassian.com/doc/setting-the-java_home-variable-in-windows-8895.html"

[]
Step 1.
Setting up your workspace.

What you first want to do is download Eclipse Mars,
Eclipse is the most used Java based programming software.

You can download Eclipse Mars here.

You probably want to download the installer since it is really easy to use,

Once you have downloaded it, simply execute it by clicking on it.

You want to download the Eclipse DSL Tool.
Simple follow the installation wizard and you will see!

When the installation is done, you simply press launch.

Step 2.
Downloading Forge Source Version.
Now you have to download the right Forge version,
since Hypixel is now only 1.8, will we download the 1.8 Forge version.
You can get the Forge files here.
In this tutorial I will use the forge version forge-1.8-11.14.1334-src, click here if you also want to use this version.

Step 3.
Setting up Forge in Eclipse

Once you downloaded the right Forge version, you can place the .ZIP file somewhere where you want your workspace.

For example, I have my Forge Files at:
C:\Users\Niek\Desktop\Forge Source versions\forge-1.8 II Hypixel Tutorial

So, if you know the location of where you want your workspace to be. Extract the Forge Files into that directory, so it will look like this.

Now press shift + right click on white space,

If you press that, the cmd will show up.

Type in the cmd,
"gradlew setupDevWorkspace eclipse"
and then press ENTER
While Forge is setting up the workspace, you can get some popcorn or something to eat :^)
If you get any errors, please quote me in a message with the error log so I can help fix it.

When it finished setting up the workspace it should say:
BUILD SUCCESSFUL

Step 4.
The enjoyable part about making Minecraft mods.
Coding.

When starting Eclipse, a message should popup,
Your workspace should be at the directory where you extracted your files, and then /eclipse so mine is:
"C:\Users\Niek\Desktop\Forge Source versions\forge-1.8 II Hypixel Tutorial\eclipse"

Then press continue.

So, everything is set up, so we are ready to go!

Disclaimer: I am not a professional, so the way I am explaining this could be confusing.

If everything went alright, you will be able to see something like this.

First, we want to rename the package,
a package is a namespace that organizes sets of classes.

How do you rename it?
Like this:

I am going to rename it to me.Niek
For a general tutorial on renaming packages, click here.

The first thing what we want to do is registering our events.
You can do that with this:

Code:

@EventHandler public void init(FMLInitializationEvent event) { FMLCommonHandler.instance().bus().register(this); MinecraftForge.EVENT_BUS.register(this); }

Now we can register our events by using @SubscribeEvent
Example:

Code:

//Fired when a chat message is about to be displayed on the client @SubscribeEvent public void onChat(ClientChatReceivedEvent event) { String message = event.message.getUnformattedText(); if(message.contains("hi")) { Minecraft.getMinecraft().toggleFullscreen(); } }

What this will do, it will toggle fullscreen if a chat message contains hi.
If you think about it, it is all really simple, but you have to understand the logic behind it

So, if you want to make a mod which shows you the amount of coins you are earning in a game.
You can do that like this.
1. Get the coin message.
2. Split the message so you only have the amount of coins, (Example: +30 coins (P2WGuy123's Network Booster, double coins weekend), try split the message in a way so the only thing you have in a message is the +30)

Since you guys may not really understand my type of explanations, will I show you how you can do it!

Code:

@SubscribeEvent public void xd(ClientChatReceivedEvent event) { String message = event.message.getUnformattedText(); //message is the message which the client receives. if(message.startsWith("+") && message.contains("coins") && !message.endsWith("for being generous")) { //Checks if the coin message you got isn't the tip message String[] splittedMessage = message.split("coins"); message = splittedMessage[0].replace("+", ""); message = message.replace(" ", ""); int coins = Integer.parseInt(message); totalCoins = totalCoins + coins; } }

So, now you have the coin message you can try to render a string on your screen by using the RenderGameOverlayEvent.

Code:

@SubscribeEvent public void render(RenderGameOverlayEvent event) { if (event.isCancelable() || event.type != ElementType.EXPERIENCE) { return; } FontRenderer fRender = Minecraft.getMinecraft().fontRendererObj; fRender.drawString(EnumChatFormatting.GREEN + "Coins: " + EnumChatFormatting.WHITE + totalCoins, 5, 5, 0); }

The rendering is done in a really simple way, I am not making it too complicated for now

So, this was my quick tutorial on how to start modding with Minecraft Forge,

If you need any help, tag me in your reply on this message please,
I hope you learned something from this,

I hope you have a nice day!

If you want to use you mod on Hypixel, make sure you ask
permission, pm JamieTheGeek if you want to use your mod,
please don't come to me if you got banned for using something.

@Nivyox - I just started doing all this stuff, but as soon as I tried to setup the Forge I got an error message:

Do you know how to fix this?

I have Eclipse Mars, I've had it for making the occasional plugin... Is that not a JDK?

Nope, that is an IDE

EDIT:
JDK stands for Java Development Kit, Eclipse mars is an program interface
