Prevents resourcepack reinstall if resourcepack was already installed by player.
An analogue of the BungeePackFix plugin by LoneDev (<3), written using Protocolize.
Implemented features:
— Prevents re-installation of the resource pack when player switches server.
— Prevents re-installation of the resource pack by request from other plugins.
— Supports multiple resource packs per player (not present in BungeePackFix, but can be easily implemented, LoneDev

).
Installation & Usage:
1. Install
Protocolize on your BungeeCord/Waterfall proxy.
2. Install ProxyPackFix on your BungeeCord/Waterfall proxy.
3. ...?
4. Done!
Commands & Permissions:
/ppf reload — configuration reload.
/ppf clearcache — forced clearing of resource pack installation history installed by players.
Commands require the
proxypackfix.commands permission.
P.S. This plugin was also written to gain experience with Protocolize, however I will continue to support customers and make updates.
