Ad Astra: Planet Screen Expanded
by LittleWindow
Ad Astra: Planet Screen Expanded extends the planet selection screen of Ad Astra with scripted, data-driven solar system rendering and a selection overlay.
What it does
Planet entries on the Ad Astra planet screen are scripted by this mod, and the solar system is rendered from .json files. Two solar systems that come with Ad Astra are already configured in these files, so they can be used without editing anything. Orbiting times, sizes and distances are set independently for each body, and moons and other orbiting objects around planets are supported.
The mod is needed by addons built with KubeJS that script the planet screen. Its files are published for Forge only, for Minecraft 1.20.1, and the environment is client and server, so the server and every player need it. The code is open source under the MIT License.
Key features
Scripted planet screen
Planet screen functions of Ad Astra are scripted, so their behaviour can be extended by data and code.
Data-driven solar system
The solar system is rendered from .json files, letting pack makers define bodies without changing Java code.
Selection overlay
A selected overlay shows which planet is chosen, making it easier to see where to land.
Configured solar systems
Configuration files for Ad Astra's two solar systems ship with the mod, ready to use as they are.
