• ✅ Dynamic pricing / fixed pricing dual modes
• ✅ Only weapons, armor, and valuable minerals are priced; miscellaneous items are free

FAQ

Q: Why did my items still drop on the ground when I died? A: This is normal. The plugin immediately removes the drops and stores them in the system, so a brief flash on the ground is expected. If items remain on the ground, the plugin is not active.

Q: I get a "Transaction Failed" error when redeeming? A: Check whether Vault and a valid economy plugin are installed. If all items are free (price 0), the free redemption will not deduct any currency.

Q: How do I change the currency name? A: Modify economy.currency-name in config.yml, then run /redeemadmin reload.

Q: Want to add/remove an item for pricing?

valuable-items:
  - +dragon_egg      # Add dragon egg for pricing

常见问题

Q: 为什么我死了物品还是掉地上了？
A: 这是正常现象。插件会立即清除掉落物并存入系统，所以地上即使闪一下也是正常的。如果物品依然留在地上说明插件未生效。

Q: 赎回时提示"交易失败"？
A: 检查是否安装了 Vault 和有效的经济插件。如果所有物品都是杂物（价格为 0），则免费赎回不会扣款。

Q: 怎么改货币名称？
A: 修改 config.yml 中的 economy.currency-name，然后 /redeemadmin reload。

Q: 想添加/移除某种物品参与计价？

valuable-items:
  - +dragon_egg      # 添加龙蛋参与计价
  - -golden_sword    # 金剑不再计价（免费）
