From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Spottedleaf <Spottedleaf@users.noreply.github.com>
Date: Fri, 30 Oct 2020 22:37:16 -0700
Subject: [PATCH] Add packet limiter config
Example config:
packet-limiter:
kick-message: '&cSent too many packets'
limits:
all:
interval: 7.0
max-packet-rate: 500.0
ServerboundPlaceRecipePacket:
interval: 4.0
max-packet-rate: 5.0
action: DROP
all section refers to all incoming packets, the action for all is
hard coded to KICK.
For specific limits, the section name is the class's name,
and an action can be defined: DROP or KICK
If interval or rate are less-than 0, the limit is ignored

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Spottedleaf <Spottedleaf@users.noreply.github.com>
Date: Fri, 30 Oct 2020 22:37:16 -0700
Subject: [PATCH] Add packet limiter config
Example config:
packet-limiter:
kick-message: '&cSent too many packets'
limits:
all:
interval: 7.0
max-packet-rate: 500.0
ServerboundPlaceRecipePacket:
interval: 4.0
max-packet-rate: 5.0
action: DROP
all section refers to all incoming packets, the action for all is
hard coded to KICK.
For specific limits, the section name is the class's name,
and an action can be defined: DROP or KICK
If interval or rate are less-than 0, the limit is ignored
