The Low-Tech AI Of Elden Ring

A technical breakdown of how FromSoftware implements NPC and boss AI in Elden Ring using a pushdown automaton built on Havok Script (a Lua variant). The system uses a stack of 'Goals' rather than a flat FSM, allowing composable, hierarchical behavior through sub-goals, weighted random action selection, interrupt callbacks for reactive behavior, and animation-driven execution. The post compares this approach favorably against Behavior Trees and planners like GOAP, arguing it is faster, more legible, and gives designers and animators meaningful control.

Visually Create Video Clips with mpv, FFmpeg and a Lua Extension — Nick Janetakis

A walkthrough of a custom Lua script for mpv that enables visual video clip creation using chapter markers and FFmpeg. The script adds four key bindings to set start/end markers, create clips, and clear markers. FFmpeg handles the actual clip extraction without re-encoding. Quality-of-life features include auto-pausing after setting the end mark, on-screen timestamp display, safe auto-incrementing file names, and preserving the original file's modification timestamp.
