Data-Driven Config and Hot-Reload

Load game data from Lua files and reload scripts at runtime.

What Is Data-Driven Design?

Data-driven design separates what (data: stats, levels, layouts) from how (code: game logic). Data changes do not require recompilation.

A config file is a Lua script that returns a table. Load it with dofile or loadfile + pcall.

-- config.lua
return {
  playerSpeed = 200,
  gravity     = 980,
  maxEnemies  = 10,
}
