🛡️ Systems & Mechanics
Combat & Damage
Added limited firing arc weapon system; converted Machine Gun Turret to limited arc and added turret adjustment mode for manual fire direction control
Weapon attack speed variation system: implemented attack speed change mechanic for Machine Gun Turret
Adjusted laser damage logic: structure damage changed to piercing damage, piercing damage is now blocked by shields
Fixed buff damage incorrectly applying an extra instance
Fixed Brawler sometimes failing to hit targets
Fixed pulse laser scatter not working
Fixed limited arc weapon angle detection issue
Reduced Mortar Turret explosion radius (Lv1 80→60, Lv2 100→70, Lv3 120→80) and minimum edge damage ratio (0.3→0.2)
Fixed weapon fire rate not being affected by bullet time
Building & Grid
Fixed map resource harvesting structures not consuming grid resources
Fixed buildings being placeable on grids occupied by rebuilding structures
Fixed building footprint invalidation after upgrading
Optimized out-of-node placement logic: hold Shift to create blueprint ghost outside layout nodes; added “[Shift] Blueprint Planning” tooltip and bottom error message when blocked
Fixed runtime error caused by AddChild when MapCopy was not ready
Fixed scrap grid resources not being consumed properly
Fixed destroyed building count not calculated correctly on the results screen, and scrap-to-gears conversion not incrementing
Unit Behavior
Fixed siege units erroneously using active attack mode
Fixed ground unit turning being overridden by flow field direction; optimized spawn orientation to face flow field direction
Fixed units idling after destroying a building
Optimized transport entity pathfinding and added loading/unloading port definition field
Buried buildings are now completely immune to all damage, cannot be targeted or attacked
Bullet Time Optimization
Construction bullet time no longer slows camera movement, and has a 1-second buffer for smooth acceleration/deceleration
