Casual Copy is a Forge 1.20.1 mod that revolves around crafting, duplication, catalysts, and player-defined recipes.
The current project contains two core machines: the Casual Synthesizer and the Void Copy Matrix.
The Casual Synthesizer is a multi-block machine. It supports two input slots, one catalyst slot, and one output slot. It supports player-defined recipes from an external configuration directory, with the final recipe synchronized to the client by the server. Recipes are loaded via JSON and support Forge Ingredient syntax such as item and tag.
The Void Copy Matrix is a single-block duplication machine used to copy items in the input slots. The output slot generates a copy and retains the ItemStack NBT.
It supports adding and modifying blacklists via server-side JSON.
