Darkness Core

Darkness Core is a shared engine library with its own shader/impact frame editor, multiverse creator and, 3D planet/space rendering system.

Multiverse — custom dimensions on a grid

A complete alternate-world system. Each “Earth” is a fixed slab of terrain living on a spiral grid inside one shared dimension, sealed off by wrap borders so players stay on their island.

• Create unlimited named worlds (“Earths”), each with its own terrain type, border size, gravity, biomes, and seed
• Terrain types: normal, dry, water, and space (pure void — for orbital builds and space stations; you fall forever instead of dying)
• Per-world gravity scaling
• Safe teleporting, per-world spawns, and an auto-transfer option for the base world
• A public API so other mods can register and jump between worlds in code

 Jade — in-world planets & sky

Real 3D planets you can see hanging in the sky and fly out to.

• Textured sphere or cube planets placed at world coordinates, with real-time axial spin
• Atmosphere glow — a soft Veil-style luminous rim around each planet
• Orbital rings (tilted, textured) around planets
• Approach & visibility distances so planets read as far away, then grow as you fly closer
• Fly into a planet to teleport down to its surface world
• Per-Earth skies: custom cubemap skyboxes, custom sun & moon, fog colour/distance, and rings arcing across the sky — all per world
• In-game planet editor (color wheel, live sliders, save/load) — everything is data-driven JSON, so packs and addons can ship their own planets and skies

Dark’s FX Engine — real time shader/impact frame editor

• A stack of screen effects: zoom blur, black & white, red tint, radial blur, chromatic aberration, vignette, bloom, edge/outline, speed lines, halftone, scanlines, screen shake, and more
• Named presets you build in-game and play by name
• Sequenced playback — chain effects with timing for impact frames and cutscene-style hits
• Multi-panel compositor for splitting the screen into comic panels
• In-game shade

For modpacks & mod developers

• Data-driven: planets and skies are JSON under data/<namespace>/jade/planet/ and .../jade/sky/. Ship your own — no code required.
• Dormant by default: with no planet/sky data present, none of the space visuals appear. The engine simply idles. Great as a pure dependency.
• API: register and teleport between worlds, drive the FX engine, and hook the planet system from your own mod.
• Addons ship their own content under their own namespace — Darkness Core is the engine, your mod is the content.
