Mathematically, -7 is one step short of -9 (which is divisible by 3). To get from -7 to -9 , you subtract 2 . In a modulus system, this wraps around to the positive equivalent.
The Kotlin Mod acts as a bridge. It bundles the Kotlin "standard library" into Minecraft, allowing mod developers to write their mods in Kotlin while ensuring the game can still understand and execute that code. Why do developers use it? kotlin mod
