How to create a plugin

You will need:

• Knowledge of JavaScript
• A code editor (I use vscode.dev (opens new window))
• Knowledge of Minecraft

What is a plugin?

A plugin is a script that is loaded by EaglerReborn on startup or when added. It can do anythin regular JavaScript do, as well as access the Plugin API.

How to make an example "Spider" hack plugin

Spider is a hack that allows you to climb up walls like a spider.

Create a new file with the .js extension, and open it in your code editor.

We will start by requiring the player. Requiring allows us to access non-automatic properties of the Plugin API.

Add this line of code:

PluginAPI.require("player");

This will allow us to access the player.

Now, we need to add a listener that will run code every game tick.
Make a function. (Name it whatever you want)

function spiderListener() {

}

Inside this function we will do two things:

• Check if the player is walking in to a wall
• If they are, add vertical motion

Let's start with checking if the player is walking in to a wall.
In the function you just made, add an if block.

if () {

}

We can check whether or not the player is walking in to a wall with PluginAPI.player.isCollidedHorizontally.

if (PluginAPI.player.isCollidedHorizontally) {

}

Now to add the vertical motion, we change the motionY property of PluginAPI.player.
I will use the += operator, which adds an amount to a variable.

In the if, add these lines:

PluginAPI.player.motionY += 0.2;
PluginAPI.player.reload();

You can change the 0.2 to something larger or smaller if you want. The reload() call is used to tell the Plugin API to update the in-game values, so we can see our changes.

Finally, we need to add the listener.

PluginAPI.addEventListener("update", spiderListener);

This tells the Plugin API to run spiderListener every game update (or tick).

Your finished code should somewhat look like this:

function spiderListener() {
    if (PluginAPI.player.isCollidedHorizontally) {
        PluginAPI.player.motionY += 0.2;
        PluginAPI.player.reload();
    }
}
PluginAPI.addEventListener("update", spiderListener);

Now, open the EaglerReborn client. Go to Options > Plugins and press "upload". Select the plugin file.

Now, when joining a server (without an anti-cheat), you should be able to climb up walls like a spider.
