Godot: pathfinding de unidades en grid hex

[leocagli]

Objetivo

Implementar el pathfinding de unidades en el grid hexagonal con costos de movimiento por terreno, zona de control y highlight de rango.

Alcance

• NavigationRegion2D adaptado a grid hex con costos por tipo de terreno
• Puntos de movimiento por unidad (3-5 según tipo)
• Costos de entrada: llanura=1, bosque=2, colinas=2, montaña=inaccesible, río=+1
• Zona de control (ZOC): las unidades enemigas bloquean el paso entre hexágonos adyacentes
• Overlay de rango de movimiento (verde) y ataque (rojo) al seleccionar unidad
• Preview del camino (línea de hexágonos resaltados) al hacer hover sobre destino

Skill de referencia

/godot-navigation-pathfinding

Tareas

• HexPathfinder.gd: implementar A* en coordenadas cúbicas hexagonales
• MovementCosts diccionario estático: { TerrainType.FOREST: 2, ... }
• ZoneOfControl.gd: calcular celdas bloqueadas por unidades enemigas adyacentes
• RangeHighlight.gd: colorear FogLayer / capa adicional con rango de mov/ataque
• PathPreview.gd: Line2D que sigue el cursor mientras se arrastra una unidad
• Integrar con UnitController.gd: al confirmar destino, iniciar movimiento (ver #godot-animations)

Aceptación

Al seleccionar una unidad, el rango de movimiento se muestra en verde; al mover el cursor, el camino se traza en tiempo real; mover a través de ZOC enemiga termina el movimiento.

I'd like to take this on.

I've worked on similar enhancements involving backend services, frontend features, and testing. I'll deliver a solution that aligns with the existing codebase, includes thorough test coverage, and is accompanied by clear documentation where necessary.
