From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: jmp Date: Thu, 20 Aug 2020 11:20:12 -0700 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.gamepedia.com/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. diff --git a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java index a98e25917193043633e2120beb4fe2d49d0e4500..b4d76494851601d61a69e2f060727a68f4461267 100644 --- a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java +++ b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java @@ -697,4 +697,17 @@ public class PaperWorldConfig { log("The Ender Dragon will be removed if she already exists without a portal.");
