From eed4fd4888acf6e4597aeaab0e9726ecbbdd23c5 Mon Sep 17 00:00:00 2001 From: dam <27978131-real_damighty@users.noreply.gitlab.com> Date: Wed, 29 Apr 2026 17:00:00 +0300 Subject: [PATCH] Added combat movement intent resolution Replaced CombatPulse's private MovementPulse pathing with an engine-side CombatMovementIntents queue resolved before normal walking queues. Exposed candidate attack tiles from CombatMovementPlanner so intents can select and reserve deterministic melee approach paths. Enabled the first pending combat movement scenario using an open wilderness fixture, added intent resolver coverage, and updated the combat movement rewrite living document. ---
