Godot: cámara (zoom, pan, edge scroll, centrar unidad)

[leocagli]

Objetivo

Implementar la cámara 2D con zoom, paneo por arrastre, scroll por bordes, teclas WASD y centrado en unidades, acotada a los límites del mapa.

Alcance

• Camera2D con límites (left/top/right/bottom) ajustados al tamaño del mapa generado
• Zoom: rueda del ratón entre 0.3× y 2.0×, con suavizado
• Paneo: clic central/arrastre derecho + teclas WASD
• Edge scroll: el cursor a ≤20 px del borde de la ventana mueve la cámara
• Space: centrar en la siguiente unidad sin órdenes (ciclo)
• Animación suave de centrado (tween) al centrar en unidad o ciudad

Skill de referencia

/godot-camera-systems

Tareas

• GameCamera.gd extendiendo Camera2D: implementar zoom con interpolación
• Paneo por arrastre: capturar InputEventMouseMotion con botón medio/derecho
• Paneo WASD: _process() con Input.get_axis y velocidad escalada con zoom
• Edge scroll: comparar get_viewport().get_mouse_position() con tamaño de viewport
• cycle_unit_without_orders(): lista de unidades sin acción, centrado con create_tween()
• Limitar posición a Rect2(map_origin, map_size) en cada frame

Aceptación

La cámara no sale de los bordes del mapa, el zoom es fluido entre 0.3× y 2.0×, y Space centra en cada unidad sin orden de manera secuencial con animación suave.
