TaCZ Blueprints

Gun blueprints are dropped by structure chests, with a default 5% chance per chest and at most one blueprint per chest. Finding a blueprint and right-clicking it teaches the recipe, after which the gun appears at the Gunsmith table. Until a blueprint is found, the matching gun cannot be crafted, which makes firearms harder to obtain and the first craft more of an achievement.

Chest loot is configurable: the drop chance, the minimum and maximum weight of each structure's blueprint entry, and which loot tables receive blueprints can all be changed. Blueprints can also be disabled entirely, so guns become craftable without research. Guns are grouped by type in the creative menu, and pistol and rifle blueprints are weighted differently by default, so more pistol blueprints turn up than rifle ones.

The mod is an addon for TaCZ: [TaCZ] Timeless and Classics Zero must be installed on Forge 1.20.1. It works with gunpacks and addons that add new guns, which are then included in the blueprint system. Ammunition and attachment blueprints are listed as work in progress and are not yet part of the release. The mod is developed by Zarra Studios and published under All rights reserved, so it is not open source, but source code is publicly available.
