Arenas inherit from a new arena_base.tscn instead of restating ~40 shared
lines each; only sky/ambient/glow/tint/decoration vary, exposed via new
Arena exports since nested Environment properties aren't overridable
through scene inheritance. Bot construction and score-keeping move onto
GameMode, shared by match and spectate modes while preserving their
differing GameSettings-override behavior and the HUD's score-row
duck-typing. HUD instruments share a HudInstrument base for the
smoothing-weight calc and angle-lerp helper. Also dedupes
MAIN_MENU_SCENE_PATH into ScenePaths and documents why DIFFICULTIES
tiers share one checkpoint.
SDFGI ran with default cascades in a volume that was almost entirely
transparent, so its low-resolution probes had little solid geometry to
capture and contributed blotching across large flat surfaces. With the
boundary now an opaque deck plus an unshaded additive field, it earns
nothing, and the existing ReflectionProbe and ambient carry the lighting.
Each arena also gains a shadowless fill light opposite its key light so the
deck is not lit from a single direction, and passes its own tint through to
the boundary's containment field so the three arenas read differently.
use_debanding was absent. Glow runs at hdr_scale 2.0 with adjustment_contrast
above 1.0, which amplifies 8-bit quantisation on exactly the kind of smooth
gradients the new shell is made of.
The remaining project.godot churn is Godot's own key reordering on save.
Adds sdfgi_enabled and a ReflectionProbe to all three arenas' Environment
setup so surfaces get real bounce lighting/reflections instead of flat
ambient. Converts arena_boundary.tscn's shared glass field material from
unshaded to a shaded, rim-lit material so it reads as glass (dim face-on,
highlighted at grazing angles) rather than a flat tinted overlay.
Enable glow/bloom, color adjustments, and MSAA+FXAA across all three
arenas so emissive ship/station accents actually bleed light and edges
read cleanly. Expose the player-facing knobs (anti-aliasing mode, glow
intensity, brightness) through a new Settings screen off the main menu,
persisted via a VideoSettings autoload that scales each arena's own
tuned Environment values on load rather than overwriting them.
Introduce arena_02 (Nebula) and arena_03 (Asteroid Field) alongside
arena_01, listed in a new ArenaRegistry (scripts/arena_registry.gd) as
the single source of truth for available arenas. Free Play lets the
player pick an arena from the main menu; Match/Spectate each pick one
at random per session; Training keeps its own fixed arena_01.
Nebula gets an RL-style visual treatment: a near-invisible glass
boundary material shared by all arenas, a baked equirect nebula sky
texture, a drifting-dust particle system, and a Blender-modeled
station/debris/planet decoration set. GameMode gains a
_get_arena_scene_path() hook so modes can instantiate their arena in
code instead of hardcoding it in the scene.
