Devlog
The devlog of a destruction game and its engine: notes from building Wreckwing and Trilithon Engine. Written with the Claude Code sessions that do the work, and reviewed by Alex before they go up.
WreckwingPilots that fly into walls and sit in alleysScripted enemy pilots hit walls and stalled in narrow streets. A review found a flaw in our first numbers, and the wall problem is still open.Postmortem · 4 minWreckwingThe muzzle flashed, but the rounds never showed upEvery ship's shots started on its own hull, so many rounds hit the ship that fired them. We fixed that and gave two ships new weapons.Dev journal · 4 minWreckwingSince 0.15: work in progressWhat has gone into the development build since release 0.15 on October 7, from a freeway and new player ships to recorded sounds. None of it is tagged yet.Release notes · 3 minWreckwingDrawing each ship's own textured modelThe game now draws each ship's own textured model, part by part, where it used to rebuild ships from convex blocks. What that took, and what it costs to draw.Dev journal · 4 minWreckwingThe ships: concept art to textured modelsThree ships to fly, the enemies built from them, and how each one goes from concept art to a textured model the game can break apart.Dev journal · 4 minStudioWhy Linear runs the projectA game built almost entirely by Claude Code sessions, and 463 Linear issues in twelve days. Why every piece of work starts and ends in Linear.Studio note · 4 minWreckwingA building that falls on the ship now hurts itA floor falling on a ship took 5% of its health. Damage now follows the weight pressing on the ship, and a collapsing tower flattens it.Dev journal · 3 minWreckwingA fast decision model for the enemy pilotsA small trained model picked goals for the enemy pilots. It beat the scripted pilot at first, then settled on one goal. The investigation continues.Dev journal · 4 minWreckwingDoubling ship toughness, and duels that wouldn't endDoubling ship toughness turned most AI duels into draws. The shield was dividing every blow too. Here is what we measured and changed.Dev journal · 2 minWreckwingAn elevated freeway for the wide cityAn elevated freeway that curves out past the city, with cloverleaf ramps you can merge from, built to the numbers real freeways use.Dev journal · 3 minWreckwingFire and smoke, picked from comparison videosOver a week we steered fire and smoke from four reference stills to a pick between side-by-side clips, and each change was measured for cost.Dev journal · 4 minWreckwingPonds, a community pool, and better splashesPark ponds that drain into craters, a community pool, and a splash redraw after the first spray read as steam and paper.Dev journal · 4 min
