Love2D's default variable timestep can make Box2D physics jitter. Learn when and how to replace love.run() with a fixed-timestep accumulator loop.
Use Lua 5.4's <close> attribute and __close metamethod to close files and other resources automatically when they leave scope, even after errors.
Switch from a Vimscript <code>vimrc</code> to a Lua <code>init.lua</code> in Neovim. This guide walks through the steps, shows example conversions, validates settings, and covers recovery options for a smooth transition.
Learn how to manage Lua tables as both arrays and associative maps. This guide covers 1-based indexing, the dangers of 'nil holes', and how to use pairs() vs ipairs() for data retrieval.
Variable dt in love.update makes physics frame-rate dependent. Learn how an accumulator-based fixed timestep clamps spikes and keeps simulation deterministic.
Lua 5.4 to-be-closed variables (<close>) tie resource cleanup to scope, not manual pcall branches. Learn how __close works, where it breaks, and how to verify it.
Run Lua scripts from C, expose host functions, and shut down the Lua state safely.
Learn how Lua coroutines enable lightweight cooperative multitasking. A step‑by‑step guide to building an async file reader, trade‑offs, and best practices for reliable, non‑blocking Lua code.
