Utilizing DuckDB-WASM for SQL Chaos Creation
In an unexpected twist, a developer named Patrick Trainer has created a unique Doom game implementation that leverages SQL instead of conventional JavaScript coding. This innovative approach involves using the Web Assembly version of DuckDB, an analytical database software, for the game's heavy lifting, challenging traditionally held notions about the capabilities of SQL.
The game, a text-based version of Doom, embodies the principle that anything can be reduced to a spreadsheet or database application, as it models the entire game world state within the database and uses SQL for real-time rendering decisions. Instead of traditional JavaScript objects or pixels drawn on Canvas/WebGL surfaces, the game world and game state are stored and manipulated within database tables.
To render the player's view, SQL raytracing is employed. Game events, such as movements, collisions, and bullet impacts, are defined as SQL statements. Upon a bullet hitting a wall or an enemy, the bullet and possibly the enemy are marked for removal.
Though JavaScript's role has been diminished in this game, it still serves a crucial function by gluing together the SQL components and handling sprite Z-buffer checks, as well as player input processing. The outcome is an ASCII-based Doom game that provides a novel gaming experience, readily accessible through the DuckDB-Doom project on GitHub.
The DuckDB-Doom project offers an educational undertaking by demonstrating the versatility of DuckDB-WASM beyond data analytics. It serves as an example of using SQL for game development by efficiently managing complex state and real-time calculations in a unique manner. With the project's source code available on GitHub, developers can delve into the intricacies of using SQL for game programming and reimagine the possibilities of database engines in creative applications.
