Combat: tame aimbot bots, fix gun viewmodels (show + orientation) - #37
Merged
Conversation
Bots played like aimbots — perfect tracking + pixel-perfect shots. Guns 2/3 barely rendered: the Deagle faced backward and neither gun really showed, just arms. Bots: - Add human aim inaccuracy: the bot now aims at a point that drifts around the true target (smoothed random walk whose amplitude grows with distance), so it over/under-shoots and misses instead of laser-beaming. Also slower turn (3.2->2.4 rad/s), longer reaction (0.75->0.9s) and tighter fire tolerance. Verified: 100 HP after standing still 13s vs the old ~1-2s instakill. The pure decideBotInput stays deterministic (wander lives in the stateful tick), so the unit tests are untouched. Gun viewmodels: - Fix the real bug behind 'guns don't show': the fit computed bone centres in WORLD space while the placement pos is CAMERA-local. It happened to work at the world origin but in-game the camera sits at z=16, so the gun was placed ~16 units behind the view. Now the fit works in the mount's (camera-local) space. - Fix the animation blend bug: draw/fire/idle all played at full weight at once and the mixer averaged them into a broken pose that threw the gun off-screen. Replace with a clean crossfade state machine (one active action; one-shots ease back to idle via the mixer 'finished' event). - Derive gun orientation from the model's own reference nodes so the barrel points forward (-Z) instead of hand-guessing Euler angles. - The AWP (clean arms+gun rig) now renders correctly as a real textured sniper held in two hands. - The Deagle Sketchfab model is a broken export — its gun and hand meshes are at incompatible 1:8000 scales in one skeleton, so no uniform transform can render both (only the hand showed). Replace it with a clean procedural Desert Eagle that renders reliably, and drop the 8 MB unused GLB + its credit. AWP credit (Addison Ye) stays.

Summary
Addresses the playtest feedback: bots felt like aimbots, and weapon slots 2/3 barely rendered (Deagle faced backward, neither gun really showed — just arms).
🤖 Bots — no more aimbot
They had perfect tracking + pixel-perfect shots. Now:

The Sketchfab Deagle's gun and hand meshes are at incompatible 1:8000 scales in one skeleton — no uniform transform can render both (only the hand showed; verified with two independent re-compressions). Replaced it with a clean procedural Desert Eagle that renders reliably, and dropped the 8 MB unused GLB + its credit. The AWP credit (Addison Ye) stays.
Verification
npm run ci: tsc clean, 132/132 tests pass, build clean.The procedural Deagle is a stopgap — if you grab a clean arms+gun Deagle rig (like the AWP, not a full-character rig), I can swap it straight in.
