Universal Blindness│通用失明
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.
Function│功能
- To put it simply, it makes the mobs only able to see objects within 4 blocks when subject to the blindness effect,just like the effect the player receives.│簡單來說，就是讓生物在受到失明效果時只能看到4格內的物體，就像玩家受到的效果一樣。
- The precise explanation is that when a creature is affected by a blinding effect, the value of "Mob Following Range" is reduced to 4, and returned to its original state when the effect wears off.│準確的解釋是，當生物受到失明效果時，將"生物跟隨範圍"的數值減少至4，並在效果消失時恢復到原來的狀態。
