Requirements

• Diablo II: Resurrected
• Diablo II: LOD 1.13c (required by https://github.com/blacha/diablo2/tree/master/packages/map)

Quick Start

Koolo will be clicking, moving the mouse, pressing keys... Basically this makes the computer unusable while running the bot. It's recommended to run it on a virtual machine.

• If you haven't done yet, install Diablo II: LOD 1.13c
• Download the latest Koolo release, or alternatively you can build it from source
• Extract the zip file in a directory of your choice.
• Open config/config.yaml with your favorite text editor and ensure D2LoDPath config is pointing to your Diablo II: LOD 1.13c installation directory.
• Configure custom bot settings under config/config.yaml and config/pickit/*.nip files for pickit rules.
• Open Diablo II: Resurrected and ensure the game resolution is set to windowed mode and 1280x720 or 1920x1080 in HiDPI mode.
• Enter the game with your character.
• Run koolo.exe.
• It should start the configured runs. You can pause/resume execution with , or stop it with . keys

How it works

Koolo reads game memory and interacts with the game simulating clicks/keystrokes. It uses the following third party libraries:

• https://github.com/hectorgimenez/d2go
• https://github.com/hectorgimenez/diablo2 (forked from blacha's repo)

Development environment

Note: This is only required if you want to build the project from source. If you want to run the bot, you can just download the latest release.

Setting the development environment is pretty straightforward, but the following dependencies are required to build the project.

Dependencies

• Download MingGW x86_64-posix-seh should be fine, extract it and add it to the system PATH on Windows environment variables. For example if extracted in C:\mingw64 add C:\mingw64\bin to the PATH. Robotgo and GoCV dependencies requires MinGW to build.
• Download CMake select add it to the user path during the installation process.
• Download Go >= 1.21
• Install git

Building from source

Open the terminal and run the following commands in project root directory:

git clone https://github.com/hectorgimenez/koolo.git
cd koolo
prepare_env.bat
build.bat

This will produce the "build" directory with the executable file and all the required assets.

Updating with latest changes

In order to fetch latest main branch changes run the following commands in project root directory:

git pull
build.bat

Note: build directory will be deleted, so if you customized any file in there, make sure to backup it before running build.bat.
