Waystones Item Cost Extended

Waystones Item Cost Extended is a Waystones add-on for compressed and decompressed item payments and combined item costs.

Configure item costs through warpRequirements in versions of Waystones that support it.

You can combine several item types in the same payment. For example, charge 3 emeralds and 2 oak logs:

warpRequirements = [
    "add_item_cost(minecraft:emerald, 3)",
    "add_item_cost(minecraft:oak_log, 2)"
]

On Minecraft 26.x, use Waystones’ Shogi syntax:

warpRequirements = [
    "item_cost('minecraft:emerald', 3)",
    "item_cost('minecraft:oak_log', 2)"
]

You can also allow items connected by reversible compression and decompression recipes to be used for payment. Set the following in config/waystones-item-cost-extended.properties, then restart the game or server:

recipePayments=true

For example, with a cost of 3 iron ingots, you can pay with 27 iron nuggets or 1 iron block and receive 6 iron ingots in change.

warpRequirements = ["add_item_cost(minecraft:iron_ingot, 3)"]

On Minecraft 26.x:

warpRequirements = ["item_cost('minecraft:iron_ingot', 3)"]

Lightmans Currency integration

On Minecraft 1.21.1 (NeoForge), Waystones Item Cost Extended provides optional native integration with Lightmans Currency (1.21-2.3.0.6+). It is never bundled and not required.

When present, registered coins can be used directly in warpRequirements:

warpRequirements = [
    "add_item_cost(lightmanscurrency:coin_iron, 20)",
    "add_item_cost(minecraft:oak_log, 2)"
]

• Coin Selection: Charges any coin registered in Lightman's native CoinAPI, including custom coin chains. Separate coin chains cannot fund one another.
• Payment Storage: Evaluates equipped native and Curios wallets via WalletHandler, hotbar slots, main inventory, and occupied offhand coin stacks. Bank accounts are not debited, and loose wallets inside inventory slots are not opened.
• Transaction Safety: Uses native CoinContainerMoneyHandler on snapshot copies of wallet contents and inventory slots. Combined item and coin costs preview together and commit after checking both inventory and wallet snapshots; all changed touched storage is guarded before commit. Native requirement rollback restores snapshots once when storage still matches the committed state; changed touched slots are never overwritten. Creative mode and zero-cost routes bypass payment entirely.
• Denomination Arithmetic & Change: Respects configured exchange rates and preserves wallet auto-exchange settings. If change cannot fit into the wallet or main inventory, the charge is refused upfront during preview, preventing partial debits or dropped items.
• Configuration: Native coin payments require no toggle. The recipePayments setting in config/waystones-item-cost-extended.properties defaults to false and solely controls reversible crafting conversions.
