Because this exploit has been widely known for years and has not been fixed by Mojang, we decided that it was worth allowing people to toggle it on/off due to how easy it is to make it configurable. It should be noted that this decision does not promise all future exploits will be configurable.

Subject: [PATCH] Add Wandering Trader spawn rate config options
|
|
|
|
Adds config options for modifying the spawn rates of Wandering Traders.
|
|
These values are all easy to understand and configure after a quick read of this
|
|
page on the Minecraft wiki: https://minecraft.wiki/wiki/Wandering_Trader#Spawning
|
|
Usages of the vanilla WanderingTraderSpawnDelay and WanderingTraderSpawnChance values
|
|
in IWorldServerData are removed as they were only used in certain places, with hardcoded
|
|
values used in other places.
