From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Jason Penilla <11360596+jpenilla@users.noreply.github.com> Date: Mon, 16 Aug 2021 01:31:54 -0500 Subject: [PATCH] Add '/paper mobcaps' and '/paper playermobcaps' Add commands to get the mobcaps for a world, as well as the mobcaps for each player when per-player mob spawning is enabled. Also has a hover text on each mob category listing what entity types are in said category diff --git a/src/main/java/io/papermc/paper/command/PaperCommand.java b/src/main/java/io/papermc/paper/command/PaperCommand.java index 27775df10a490ff75ca377e8373931738f1b817c..c9bb2df0d884227576ed8d2e72219bbbd7ba827e 100644 --- a/src/main/java/io/papermc/paper/command/PaperCommand.java +++ b/src/main/java/io/papermc/paper/command/PaperCommand.java @@ -40,6 +40,7 @@ public final class PaperCommand extends Command { commands.put(Set.of("dumpplugins"), new DumpPluginsCommand());
