Blocks of planents and stars
by MisterCosmos
Blocks of planents and stars is a NeoForge game mechanics mod that adds three cosmic blocks, each with its own effect on nearby objects and the landscape.
What it does
Three blocks themed on planets and celestial bodies join the game, and each one triggers a distinct effect. The Sun block sets objects on fire, the Betelgeuse block sets objects on fire for 60 seconds, and the Moon block changes the surrounding landscape. Custom sound events play when these blocks are used, adding to the atmosphere of a build or a map.
The mod is built on NeoForge and integrates with game logic through mixins, so its behavior hooks into existing systems rather than replacing them. Its effects are described by the author as balanced, with clear and noticeable results. Clients and servers both need the mod, since it runs on client and server together.
Files are published for NeoForge only, for 1.21.1 and 1.21.4, with 1.0.0 for 1.21.4 as the latest build. The code is released under the MIT License and is not open source.
