After a bit long time of creating Fabric mods for Minecraft. I collected some tips and tricks that I found useful for mod development and want to share it. Because I’m not good at Java so these codes below are written in Kotlin.

1. Utilities functions

These life savers functions that I always use when developing mods.

1.1 toEnglishName(path)

import java.util.Locale

fun toEnglishName(name: String): String {
        return name.lowercase(Locale.ROOT).split("_").joinToString(" ") {
            it.replaceFirstChar { char -> char.uppercaseChar() }
        }
    }

This function will convert a name with any formats (camel_case, snake_case, etc.) to readable English name. For instance: wrench -> Wrench lava_generator -> Lava Generator

2. Utilities classes

2.1 Identifier

Instead of spamming long ResourceLocation, we should make a class extends it and only receive path. This will decrease the amount of code we need to write.

class Identifier(path: String) : ResourceLocation(MOD_NAME, path) {}

By using that, we can replace this:

val wrench = ResourceLocation(MOD_ID, "wrench")
val lavaGenerator = ResourceLocation(MOD_ID, "lava_generator")

to this:

val wrench = Identifier("wrench")
val lavaGenerator = Identifier("lava_generator")
