Game Dialog Script Language

A simple language for creating game dialogs. Write dialogs as plain text with a bit of logic, and the interpreter does the rest.

The language seamlessly integrates with C# and works great in Unity and Godot with Mono. You can follow the language development progress on the project board.

What It Looks Like

Here's how a merchant dialog looks that greets the player differently based on reputation:

reputation = 75

<< "Welcome, traveler!"

if reputation > 50
    << "Good to see you again, friend!"
    << "I have a special discount for you."
else
    << "I don't know you."
    << "Regular prices."

That's it! No complex configurations, JSON files, or XML markup. Just write text and add a bit of logic.

Works with C# Out of the Box

Integrating the interpreter into your Unity or Godot project is dead simple. Here's all the code you need:

using BitPatch.DialogLang;

var script = @"
playerName = ""Arthur""
<< ""Hello, "" + playerName + ""!""
<< ""How are you doing?""
";

var dialog = new Dialog();
foreach (var line in dialog.Execute(script))
{
    Console.WriteLine(line);
}

The interpreter returns strings one by one, and you simply display them on screen. No callbacks, delegates, or complex integrations. Load the script, run it, get the dialogs.

Why It's Convenient

The entire dialog is in one file. Open it in any text editor and immediately see all the logic. Want to change a line or a condition? Just edit the text and save. No need to switch between a dialog editor, game engine, and code.

This format makes team collaboration easy. Scripts are stored in Git alongside the code, and you can see all changes in commit history. A writer can change the text, a game designer the conditions, and a programmer integrates it into the game. Everything in one place.

And one more bonus: neural networks understand this language perfectly.
