# PacketEvents
|
||||
Listen to minecraft packets and send minecraft packets.
|
||||
# packetevents by retrooper
|
||||
|
||||
Credit to TinyProtocol
|
||||
A lightweight spigot packetlistener & packetsender coded by retrooper.
|
||||
|
||||
PacketEvents coded by purplex.
|
||||
## Credit:
|
||||
|
||||
Coding help discord server: https://discord.gg/ZWTkg4v
|
||||
PacketEvents uses a modified version of [TinyProtocol](http://github.com/dmulloy2/ProtocolLib/blob/master/TinyProtocol/src/main/java/com/comphenix/tinyprotocol/TinyProtocol.java) by [@DeprecatedLuke](https://github.com/DeprecatedLuke) to support 1.7.10 & 1.8.
|
||||
I modified DeprecatedLuke's version of TinyProtocol and added support for 1.9+ versions.
|
||||
|
||||
Examples can be found at
|
||||
me/purplex/packetevents/example/TestExample.java
|
||||
PacketEvents also took Atlas' Packet class.(all the packet names)
