Plugin CustomItemAPI

CustomItemAPI

CustomItemAPI is a developer focused plugin for Paper servers running Minecraft 1.20 and later. It provides an API for creating custom items and blocks without relying on a traditional client side mod. Server creators can define content through JSON packs or register it directly from another plugin, using namespaced identifiers, custom textures, tags, actions, and model data.

Custom blocks can use different base blocks, support rotation, respond to placement, breaking, and interaction, and drop linked custom items. Their visual presentation relies on resource pack models and item displays, making CustomItemAPI a practical foundation for RPG, survival, and minigame content on a Minecraft server. At BoxToPlay, we see it as a flexible tool for expanding server gameplay.
