Economical Villager Trading

Minecraft 1.16 mod for the Fabric mod loader. 

Notice: this mod may cause a crash on Java versions other than Java 8, and definitely crashes on Java 15. 

This is due to a problem with Mixin, the system Fabric uses to alter vanilla Minecraft code. 

You can view the issue on the Mixin repo here, and on this project's repo here.  

This mod replaces vanilla's villager restocking mechanic. Villagers will no longer be limited to a few restocks a day.

Instead, every time you lock out a villager trade, if the newly locked trade was a buy trade, the villager will restock all of their sell trades. Likewise, if the newly locked trade was a sell trade, the villager will restock all of their buy trades. 

A sell trade is any trade that gives the player emeralds. All other trades are buy trades. 

In addition, every time the villager levels up, or if all of a villager's trades ever become locked out, they will restock all of their trades. This is to ensure a villager will never be stuck in a state where you can't trade with them at all. 

The rational for this mod is that it eliminates the need for having lots of villagers with the same trades, and as a result should reduce lag. Villagers are fairly laggy, so having lots of them can greatly affect performance. 

In addition to reducing lag, this new restock mechanic:

- eliminates tedious waiting for villagers to restock

- makes you use more than one of a villager's trades, adding a little depth to trading and encouraging more/diverse farms

- makes the villager economy make a little more sense since it can't be completely one-sided buying or selling

When connecting to a server, clients do not need this mod installed.

This mod is only for Fabric and I won't be porting it to Forge. The license is MIT, however, so anyone else is free to port it.

I'd appreciate links back to this page if you port or otherwise modify this project, but links aren't required.
