PCA · PreCraft Accelerator analyzes recipes and prepares the required intermediate ingredients directly from recipe-viewer interfaces. It supports single and bulk operations, handles each prerequisite independently, and works with vanilla crafting menus, JEI, Sophisticated Backpacks, and servers without PCA installed.

PCA · PreCraft Accelerator 是一款配方前置合成辅助 Mod，可从配方查看界面分析并制作最终配方所需的前置物品。它支持单次处理与批量处理，可独立判断各项前置材料，并兼容玩家合成栏、原版工作台等原版合成容器。当前版本依赖 JEI 作为物品与配方管理器，后续将逐步增加对 REI、EMI 等同类 Mod 的兼容。非原版容器方面，目前仅兼容精妙背包及其合成升级，其他存储或合成容器暂未支持。PCA 支持客户端独立使用，服务器未安装本 Mod 时也可正常运行。

PreCraft Accelerator

PreCraft Accelerator, abbreviated as PCA, adds a prerequisite-crafting button to supported JEI recipe displays.

Instead of manually crafting every intermediate ingredient, PCA checks the materials you already have, determines which prerequisites are actually missing, and prepares them through normal crafting interactions.

Features

• Adds a dedicated prerequisite-crafting button to supported JEI recipe pages.
• Left-click prepares the prerequisites required for one crafting operation.
• Shift + Left-click prepares the maximum amount supported by the available materials.
• Uses existing ingredients and intermediate items before crafting new ones.
• Only recursively crafts quantities that are genuinely missing.
• Reserves materials that can directly satisfy the final recipe.
• Avoids unnecessary conversion of valid materials into other intermediate items.
• Supports recipes with multiple valid ingredient alternatives and item tags.
• Displays readable messages when required materials are unavailable.
• Prevents unsupported screens from showing a button or hidden click area.

Material-Efficient Planning

PCA is designed to reduce unnecessary material consumption.

Before recursively crafting anything, it:

1. Reads the final recipe.
2. Checks the player’s currently available materials.
3. Reserves items that already satisfy the final recipe.
4. Calculates the remaining ingredient shortages.
5. Crafts only the missing prerequisites.
6. Prefers valid crafting paths with lower material consumption and less excess output.

For example, when preparing a Smoker, valid logs or wood are preserved for the final recipe instead of being unnecessarily converted into planks.

Supported Crafting Environments

Support depends on the Minecraft version and loader build.

Currently supported environments may include:

• Player inventory 2×2 crafting grid.
• Vanilla crafting table.
• Supported crafting containers provided by compatible mods.

PCA uses separate handling logic for vanilla and supported modded containers. Unsupported containers remain untouched.

Client-Side Use

PCA is designed to operate through normal Minecraft and container interactions.

On supported configurations, it can be installed on the client without requiring the server to install PCA.

The server still validates the actual inventory and crafting operations.

Requirements

• A supported Minecraft mod loader.
• JEI for the corresponding Minecraft version.
• Loader-specific dependencies required by the selected PCA file.

Optional compatibility mods are not required for PCA’s base functionality unless explicitly stated on the individual version page.

Important Notes

• PCA prepares missing prerequisites; it does not replace the normal recipe result.
• A 2×2 crafting grid may prepare valid intermediate ingredients even when the final recipe requires a 3×3 crafting grid.
• PCA does not treat materials as available unless they can actually be accessed and used.
• Automatic machine processing and external autocrafting systems are not used unless a specific version explicitly supports them.
• Features and integrations may vary between Minecraft versions and mod loaders.
