Eternal Nether Star│永恆的下界之星
Java data pack listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Introduce│介紹
- The entity form of a nether star does not automatically disappear after 10 minutes, but exists forever. Same as Bedrock Edition.│物品實體型態的下界之星不會在10分鐘後被自動清除掉，而是永遠存在。與基岩版一致。
- Nether star item entities are immune to all damage.(This feature requires the "Item Components" mod to be installed in order to function.)│下界之心物品實體免疫一切傷害。（這個功能需要安裝模組"物品組件"才能運作）
