ExtendedPick

ExtendedPick is a Minecraft Forge mod that significantly upgrades the standard "Pick Block" (Middle-Click) functionality. It allows players to find items in their inventory more intelligently, even if the item is buried inside a backpack or has slightly different NBT data.

Features

1. Smart / Fuzzy Matching

The vanilla Pick Block function requires an exact item match. ExtendedPick introduces ISearchHelper, allowing for "best match" scoring.

If you try to pick a block and don't have the exact item, the mod searches your inventory for the most similar item based on registered logic.
It prioritizes the Hotbar but will swap items from the main inventory if necessary.

2. Deep Search (Container Support)

If the item isn't found in your main inventory, ExtendedPick can search inside item containers (like Backpacks, Shulker Boxes, or Bundles) that you are carrying.

This is handled via the IDeepSearchProvider API.
Forge Capability Support: Items implementing ForgeCapabilities.ITEM_HANDLER are supported automatically by default.
If the item is found inside a container, the mod communicates with the server to extract it automatically (configurable).

3. Advanced Creative Entity Picking

Enhances Creative Mode picking for entities:

Ctrl + Pick Block (Middle Click) on an Entity will copy the Entity with its full NBT data (excluding position/UUID), allowing you to place down an exact copy of that mob.

4. JEI Recipe Transfer Integration

Extends the "Deep Search" logic to Just Enough Items (JEI).

When clicking the "+" button to transfer a recipe into a crafting grid, ExtendedPick will automatically search for and extract required ingredients from inside your carried containers (Backpacks, etc.) if they are missing from your main inventory.

5. Configurable

The mod allows customization via ExtendedPickClientConfig:

Toggle Deep Search.
Enable/Disable debug logging for picking actions.
Toggle Creative NBT picking behavior.

For Developers (API)

ExtendedPick provides an API for other mods to integrate their items and containers.

`ISearchHelper`

Implement this interface to define how two items should be compared (Fuzzy Search).

public class MyISearchHelper implements ISearchHelper {
    @Override
    int getMatchScore(@NotNull ItemStack target, @NotNull ItemStack candidate){
       //Logic to Match Score
    }
}

`IDeepSearchProvider<T>`

Implement this interface to allow ExtendedPick to look inside your mod's containers. T represents your internal index type (e.g., Integer for slot ID).

public class MyBackpackProvider implements IDeepSearchProvider<Integer> {
    @Override
    public void forEachItem(@NotNull ItemStack container, @NotNull Predicate<IndexedStack<Integer>> action) {
        // Logic to iterate container contents. Return true/false in predicate to continue/stop.
    }

    @NotNull
    @Override
    public ItemStack extract(@NotNull ServerPlayer player, @NotNull ItemStack container, @NotNull Integer index, int amount, boolean simulate) {
        // Logic to remove item from container and return it
        // amount: 0 (MAX_STACK_SIZE) or specific count
        // simulate: if true, do not actually modify the stack
    }
}
