From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Jason Penilla <11360596+jpenilla@users.noreply.github.com> 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 4880bb961c8bf87dd4e5538c091826b6be1a0e19..b3c29c9796eafc220d7838ba2add9c8d81ba4659 100644 --- a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java +++ b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java @@ -61,6 +61,19 @@ public class PaperWorldConfig { } } + public int wanderingTraderSpawnMinuteTicks = 1200;
