[OpenDiablo2](https://opendiablo2.com/) is an ARPG game engine in the same vein of the 2000's games, and supports playing Diablo 2.
|
||||
|
||||
## About this project
|
||||
The engine is written in Go and is cross platform.
|
||||
|
||||
OpenDiablo2 is an ARPG game engine in the same vein of the 2000's games, and supports playing Diablo 2. The engine is written in golang and is cross platform. However, please note that this project does not ship with the assets or content required to play Diablo 2. You must have a legally purchased copy of [Diablo 2](https://us.shop.battle.net/en-us/product/diablo-ii) and its expansion [Lord of Destruction](https://us.shop.battle.net/en-us/product/diablo-ii-lord-of-destruction) installed on your computer in order to run that game on this engine. If you have an original copy of the disks, those files should work fine as well.

|
||||
|

We are currently working on features necessary to play Diablo 2 in its entirety. After this is completed, we will work on expanding the project to include tools and plugin support for modding, as well as writing completely new games with the engine.

## Building
|
||||
### 🔥 For Developers
|
||||
|
||||
To pull the project down, run `go get github.com/OpenDiablo2/OpenDiablo2`
|
||||
|
||||
On windows this folder will most likely be in `%USERPROFILE%\go\src\github.com\OpenDiablo2\OpenDiablo2`
|
||||
|
||||
In the root folder, run `go get -d` to pull down all dependencies.
|
||||
|
||||
To run the project, run `go run .` from the root folder.
|
||||
|
||||
You can also open the root folder in VSCode. Make sure you have the `ms-vscode.go` plugin installed.
|
||||
|
||||
### Linux
|
||||
|
||||
There are several dependencies which need to be installed additionally.
|
||||
To install them you can use `./build.sh` in the project root folder - this script takes care of the installation for you.
|
||||
|
||||
## Contributing
|
||||
|
||||
If you find something you'd like to fix that's obviously broken, create a branch, commit your code, and submit a pull request. If it's a new or missing feature you'd like to see, add an issue, and be descriptive!
|
||||
|
||||
If you'd like to help out and are not quite sure how, you can look through any open issues and tasks, or ask
|
||||
for tasks on our discord server.
|
||||
|
||||
**As of Oct. 26, 2020 we will no longer be accepting pull requests that introduce lint errors.**
|
||||
|
||||
We use `golangci-lint` to catch lint errors, and we require all contributors to install and use
|
||||
it. Installation instructions can be found [here](https://golangci-lint.run/usage/install/).
|
||||
|
||||
## VS Code Extensions
|
||||
|
||||
The following extensions are recommended for working with this project:
|
||||
|
||||
* ms-vscode.go
|
||||
* defaltd.go-coverage-viewer
|
||||
|
||||
When you open the workspace for the first time, Visual Studio Code will automatically suggest these extensions for installation.
|
||||
|
||||
Alternatively you can get to it by going to settings <kbd>Ctrl+,</kbd>, expanding `Extensions` and selecting `Go configuration`,
|
||||
then clicking on `Edit in settings.json`. Just paste that section where appropriate.
|
||||
|
||||
## Configuration
|
||||
|
||||
The engine is configured via the `config.json` file. By default, the configuration assumes that you have installed Diablo 2 and the
|
||||
expansion via the official Blizzard Diablo 2 installers using the default file paths. If you are not on Windows, or have installed
|
||||
the game in a different location, the base path may have to be adjusted.
|
||||
|
||||
## Profiling
|
||||
|
||||
There are many profiler options to debug performance issues. These can be enabled by suppling the following command-line option and are saved in the `pprof` directory:
|
||||
|
||||
`go run . --profile=cpu`
|
||||
|
||||
Available profilers:\
|
||||
`cpu` `mem` `block` `goroutine` `trace` `thread` `mutex`
|
||||
|
||||
You can export the profiler output with the following command:\
|
||||
`go tool pprof --pdf ./OpenDiablo2 pprof/profiler.pprof > file.pdf`
|
||||
|
||||
Ingame you can create a heap dump by pressing `~` and typing `dumpheap`. A heap.pprof is written to the `pprof` directory.
|
||||
|
||||
You may need to install [Graphviz](http://www.graphviz.org/download/) in order to convert the profiler output.
|
||||
|
||||
## Debugging
|
||||
|
||||
### Layouts
|
||||
|
||||
Layouts can show their boundaries and other visual debugging information when they render. Set `layoutDebug` to `true` in `d2core/d2gui/layout.go` to enable this behavior.
|
||||
|
||||
|
||||
|
||||
## Roadmap
|
||||
|
||||
There is an in-progress [project roadmap](https://docs.google.com/document/d/156sWiuk-XBfomVxZ3MD-ijxnwM1X66KTHo2AcWIy8bE/edit?usp=sharing),
|

# Install OpenDiablo2
|
||||
|
||||
We currently provide binaries only for [Patreon supporters](https://www.patreon.com/bePatron?u=37261055) to [download and auto-update](https://www.patreon.com/posts/thanks-for-38407582).
|
||||
If you are not one of those, you need to follow the developer documentation for building the project using Go.
|
||||
|
||||
Once you have an executable/binary of OpenDiablo2 (either provided via Patreon or building your own), then just launch it.
|
||||
|
||||
### Error? It's expected!
|
||||
|
||||
In case there is an error, it's most likely related to MPQ files.
|
||||
You need to modify `config.json`.
|
||||
|
||||
Run the binary once; it should let your know where the location of this file is.
|
||||
For example:
|
||||
|
||||
|
||||
|
||||
In this specific case (MacOS) the file is located at: `~/Library/Application\ Support/OpenDiablo2/config.json`
|
||||
|
||||
Make sure the file looks like this:
|
||||
|
||||
```json
|
||||
{
|
||||
"MpqLoadOrder": [
|
||||
"patch_d2.mpq",
|
||||
"d2exp.mpq",
|
||||
"d2xmusic.mpq",
|
||||
"d2xtalk.mpq",
|
||||
"d2xvideo.mpq",
|
||||
"d2data.mpq",
|
||||
"d2char.mpq",
|
||||
"d2music.mpq",
|
||||
"d2sfx.mpq",
|
||||
"d2video.mpq",
|
||||
"d2speech.mpq"
|
||||
],
|
||||
"MpqPath": "/Applications/Diablo II/",
|
||||
"TicksPerSecond": -1,
|
||||
"FpsCap": 0,
|
||||
"SfxVolume": 1,
|
||||
"BgmVolume": 0.3,

||||
"RunInBackground": true,
|
||||
"VsyncEnabled": true,
|
||||
"Backend": "Ebiten"
|
||||
}
|
||||
```
|
||||
|
||||
Pay attention to the `MpqPath` directory (you can also change this to whatever location your like).
|
||||
Now copy-and-paste the MPQ files from you Windows PC into that directory.
|
||||
Make sure the filenames are matching the ones from `config.json`,
|
||||
|
||||
Now, launch OpenDiablo2 again and this time it should work!

# Locate MPQ files

The MPQ files should be present at your Diablo II installation directory.

# Purchase the official game
|
||||
|
||||
1. Buy [Diablo II (2000)](https://eu.shop.battle.net/en-gb/product/diablo-ii).
|
||||
|
||||
|
||||
|
||||
2. Write down your CD-Key and start downloading the game.
|
||||
|
||||
|
||||
|
||||
3. The Blizzard Downloader works only with Windows. Find a Windows PC and download the game.
|
||||
|
||||
|
||||
|
||||
4. Save the installer setup executable somewhere temporarily in your disk (e.g. `C:/Diablo II`) and wait until the download is complete.
|
||||
|
||||
|
||||
|
||||
5. When the download is finished the setup will automatically start Diablo II Installer.
|
||||
|
||||
|
||||
|
||||
6. Begin the installation! Right after accepting the license, it will ask you to insert a name and copy-paste your CD-Key (from step 2).
|
||||
In case you forgot to save it, there should be already an e-mail at your inbox about it.
|
||||
|
||||
|
||||
|
||||
7. Select a directory to install the game.
|
||||
Ideally, use the default location: `C:\Program FIles(x86)\Diablo II`.
|
||||
|
||||
|
||||
|
||||
8. Run the game.
|
||||
If you are using `Windows 10` you will get a message prompt saying `Run the program without getting help`.
|
||||
Next, click `Don't show this message again` to avoid future noise.
|
||||
|
||||
9. After the game launches make sure the version is **1.14b**.
|
||||
|
||||
|
||||
### Repeat the exact process for Diablo II: Lord of Destruction
|
||||
|
||||
11. Buy [Diablo II: Lord of Destruction (2001)](https://eu.shop.battle.net/en-gb/product/diablo-ii-lord-of-destruction).
|
||||
|
||||
|
||||
|
||||
12. Repeat the steps **from 2 to 9** for Diablo II: Lord of Destruction.
