Entropy Descent

About

Entropy Descent is a tactical, grid-based roguelike. The game focuses on strategic movement, combat, and narrative progression within a dynamically simulated environment.

Architecture: The Odin Pivot

This project was recently rewritten from the ground up, porting from C++23 to the Odin programming language. The goal of this transformation was to eliminate build friction, drop object-oriented overhead, and fully embrace Data-Oriented Design (DOD).

Key Technical Shifts

  • Language: Odin replaced C++.
  • Custom ECS: The third-party EnTT library was removed. The engine now uses a custom, from-scratch Entity Component System utilizing Odin's native #soa (Structure of Arrays) for cache-friendly memory access.
  • No Build Systems: CMake and associated build scripts were removed. The project relies exclusively on the native Odin compiler for instant iteration times.
  • Flat Architecture: Logic is strictly separated from data. State is held in plain data structs, manipulated by isolated, procedural systems.
  • Rendering & Input: Handled via direct, zero-abstraction calls to Odin's vendor:sdl3 library.

Building and Running

Ensure you have the Odin compiler and SDL3 installed on your system.

To compile and run the game, navigate to the project root and execute:

odin run .
