About this Mod
TestFabricAddItemMod1
Overview of this Mod
A mod made by 1510ty that adds items and blocks.
This mod was created as a trial by 1510ty, a Java beginner.
Please don't expect too much.
Versions prior to 3.1.1 are available on Github.
However, most of them are not translated into English and there are no explanations for the mods, so I don't recommend them.
This mod was created using IntelliJ IDEA.
Please note: 1510ty is Japanese, so some of the content of the mod may be in Japanese and some of the English may be translated, so you may feel uncomfortable.
