From 4e56c3bfae5a83a1b0b5f33185739f53a34c7b89 Mon Sep 17 00:00:00 2001 From: Brian Fertig Date: Sat, 25 Jul 2026 08:23:11 -0600 Subject: [PATCH] feat(totalannihilation): add victory conditions, new defensive towers, and combat improvements - Introduce configurable victory modes: "commander" (default, kill enemy commander) and "annihilation" (fight until army can no longer produce) - Add Laser Tower (1x1, hitscan) and Missile Launcher (2x2, guided with min-range dead zone) as buildable defensive structures with new towerlaser and towermissile weapons - Units now hold at weapon range when attacking buildings instead of closing to point-blank, controlled by new engageHoldFraction constant (0.45) - Replace center-to-center distance with surface distance for building targets; buildings are treated as rectangles with true half-extents, improving combat accuracy - Buildings (towers) now freely traverse and aim in all directions regardless of art orientation - Commander unit flagged with isCommander; victory conditions validate presence of commanders - Update campaign missions to use destroyCommander objective; reseed m02 (old seed unwinnable after combat balance changes) - Add skirmish setup UI for selecting victory conditions - Update AI skill ladder verification thresholds to account for engage hold behavior - Add comprehensive tests for victory conditions and defensive structures --- data/totalannihilation-campaign.json | 140 +++++------ data/totalannihilation-rules.json | 141 ++++++++++- src/data/gamesRegistry.js | 10 +- src/games/totalannihilation/TAArt.js | 56
