The Editor (JavaScript)

The Editor

> Tutorial

The editor, which you open from the "Editor" tab in the menu, is where you develop your AI.

What is an AI?

An artificial intelligence (AI) is a piece of code, written here in JavaScript (or TypeScript), that controls your leek during its turn. The code you write runs at the start of each of your leek's turns and decides the actions it takes: attacking, moving, using a weapon or a chip…

Here's a very simple example of an AI:

Once a fight has started, you can no longer step in to control your leek's actions: only the AI counts, which is why it's essential to program it carefully.

Your AI runs in a standard JavaScript engine (ES2026). TypeScript (5.8) is also supported: you can add type annotations, which are checked and then removed before the fight.

The editor interface

The editor lets you create and edit your AIs. Once you've written your code, save it with the File > Save button or the Ctrl + S shortcut. When you save, any errors the editor detects are shown in red.

The editor also has many keyboard shortcuts that can save you time while developing your AIs. Here are the most useful ones to get started:

• Ctrl + S: save the current AI
• Ctrl + Q: start a test fight to try out your AI in an unranked fight
• Ctrl + F: search in the current file
• Ctrl + Shift + F: search in all files
• Ctrl + Space: autocomplete
• Alt + Shift + F: automatically format and indent the code
