PolarisTrading

by zhifan · on CurseForge

This mod adds a Market Block for trading between players. Players can set the items they want to sell and what they are willing to buy in return.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

⬇ Download for 1.21.1 · NeoForge ⬇ Download for 1.20.1 · Forge

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

关于模组

本模组添加了可供玩家之间相互交易的市场方块。

玩家可以自由设定所出售的物品以及想要收购的物品。

如何使用该模组

玩家放置市场方块后使用市场工具右键点击市场方块进行编辑。

将想要收购的物品放入市场编辑区域的左边格子内。

将想要出售的物品放入市场编辑区域的右边格子内。

然后输入单次收购与单次出售物品的数量，点击设置后即可进行交易。

别忘记补充库存。

被出售的物品会在市场方块内显示：

玩家贴近商店或蹲下查看商店时，会出现悬浮 UI

当库存内无出售物品或者收购的物资栏满后 UI 会显示一个红红的 × 来表示无法交易。

当你手持被收购的物品时会出现一个绿色的 √ 来表示可以交易

这时手持被收购的物品右键市场方块即可进行交易。

无限商店

管理员可以使用无限商店工具对已经配置好的商店右键使其成为无限商店。

无限商店不需要补充货物也可以就行出售商品，但同时也不会获得货币。

只有拥有 OP 权限的玩家才能使用无限商店工具对商店进行设置。

附加内容

当市场方块被放置时，会绑定放置市场方块的玩家；
市场方块只能被绑定该方块的玩家设置或者拆除(创造模式也可以直接拆）；
市场方块只能使用市场工具进行挖掘；
玩家空手蹲下右键可以查看该市场方块所属的玩家 ID。
