ChatLane

A tool to customize the chat wheel of Valve's game Deadlock:

• Create custom chat wheel menus. Name, icon and contents can be customized.
• Unlock voice commands that are normally not bindable.
• One click to generate an add-on VPK file, ready for use in the game.
• Share configs with your friends or online! You can directly load the VPKs, without needing to extract.
• Graphical interface for easy use, as well as a command-line tool for nerds.

Disclaimer

• Deadlock is in early alpha, so this tool and add-on may stop working at any moment.
• As the tool edits a game file (specifically a script file), I am not responsible for any bans for users of this tool. Valve does not have a clear stance on what's fair game when it comes to modding Deadlock yet!

Installation and Usage

To get ChatLane, download the latest release's zip archive.

Extract everything somewhere, then run the ChatLane-GUI.exe file.

On the left, you have an overview of all voice commands in the game. Those with a checkmark are hidden by default, for various reasons (see the corresponding headers in the list for more info). You can enable them so that they show up in the "Chat Wheel" settings of Deadlock as additional options.

On the right you can define custom menus. Create a new menu, give it a name and icon, then you can decide what voice lines should be inside. Use drag and drop from the left list onto the right box to assign voice lines to the menu. You can also use drag and drop to re-arrange the elements inside the list. When in-game, you will see the new custom menus you've created at the bottom of the "Chat Wheel" settings.

In order to be able to see your changes, you must set up your Deadlock for modding.

Once done, ChatLane can directly save pakXX_dir.vpk files without any intermediate steps! Just place it in the addons folder and you're done.

Open the game's settings and go to the Chat Wheel tab. This should now feature your new custom menus at the bottom, as well as any hidden voice commands you've decided to enable.

If you later want to edit your config, you can simply load the VPK file again, do your changes, then save and overwrite it.

To uninstall the add-on, you can rename or delete the VPK file. You MUST also enter the chat wheel settings and unbind any custom entries! Failing to do so will cause the game to crash when opening the chat wheel.

Known bugs and limitations

Entries in this list can not be fixed easily, due to how the chat wheel system of Deadlock works. The list will be updated as Valve fixes them.

• If you removed a custom menu (or uninstalled the add-on), you have to manually unbind the "blank" entries in the game's chat wheel settings. Otherwise, opening the chat wheel will crash your game!
• A custom menu can have up to 12 entries, filling up the entire circle.
• Having multiple menus on the wheel causes the menu to show incorrect contents.
• Menus sometimes open in the wrong direction, making them unusable. Simply bind them to another direction.
• A placeholder voice line plays when you select a custom menu (when not selecting one of its entries).

For any other bugs, it's either an issue with ChatLane, or a new game update broke the add-on. In either case, feel free to open an issue so that we can figure it out!

Technical info

Read on for all those developers, contributors and reverse-engineers among you.

Repository structure

• CLI: A bridge that converts between a human-readable interchange YAML config format, and a fully bundled VPK add-on which can be loaded as-is into Deadlock.
• GUI: A layer on top of the CLI which allows for graphical modification of the config.
• tools: Scripts for building and deploying.

Building

Only Windows builds are supported, since that is all I currently have access to. Contributions are welcome, and I will try my best to help with any issues encountered!

The script tools/prepare_build.ps1 prepares all projects and builds them in the same way as the release zip archives. The result can be found in the build folder which will be generated in the repository root.

If you only wish to compile a part of the project (e.g. just the CLI or just the GUI), look inside the prepare_build script.

CLI

You will need .NET 8 SDK installed. No further preparation is needed.

GUI

You will need to place Godot executables so they can be discovered by the tooling, like so:

ChatLane
  GUI
    bin
      windows
        executables
          godot.windows.editor.x86_64.console.exe
          godot.windows.editor.x86_64.exe
          godot.windows.template_release.x86_64.console.exe
          godot.windows.template_release.x86_64.exe

Download the custom Godot 4.4 build that was used for this. It relies on this pending PR as well as some minor bug fixes [1][2]. When using official 4.4 builds instead, you may be able to circumvent the errors caused by the unmerged PR by replacing tmp:// paths in the project.

Additionally, a build profile was used to reduce the export template file size slightly:

scons target=template_release build_profile="GUI/GUIdot.build"

Troubleshooting

• None of the UI strings are translated.
  • Open the GUI project in Godot (see instructions above for executable download) and launch the project with F5. Then re-run the prepare_build.ps1 script.
• Compiling the CLI shows warnings.
  • These are expected, see #1 for cleaning them up.
• Compiling the GUI shows errors.
  • Some errors are expected, due to how Godot loads the editor headless, or due to the fluent add-on. Simply check if the export succeeded, and if the app works as expected, without worrying much about the error logs.
