To listen to packets simply create and register a PacketListener:
Code (Java):
PacketEventManager eventManager
= PacketInjectorPlugin.
getInstance
(
).
getPacketInjectorAPI
(
).
getEventManager
(
)
;
eventManager. registerPacketListener (pluginInstance, new PacketListener ( ) {
@Override
public void onSend (PacketSendEvent event ) {
// code
}
@Override
public void onReceive (PacketReceiveEvent event ) {
// code
}
} ) ;
eventManager. registerPacketListener (pluginInstance, new PacketListener ( ) {
@Override
public void onSend (PacketSendEvent event ) {
// code
}
@Override
public void onReceive (PacketReceiveEvent event ) {
// code
}
} ) ;
See LightInjector javadoc for more information.
Spoiler: Events Methods
Code (Java):
Player player
= event.
getPlayer
(
)
;
// Might be null (see above)
Object packet = event. getPacket ( ) ;
String packetClassName = event. getPacketName ( ) ;
event. setCancelled ( true ) ; // Stops the packet
event. setPacket (newPacket ) ;
Object value = event. getValue ( "fieldName" ) ;
event. setValue ( "fieldName", value ) ;
Object packet = event. getPacket ( ) ;
String packetClassName = event. getPacketName ( ) ;
event. setCancelled ( true ) ; // Stops the packet
event. setPacket (newPacket ) ;
Object value = event. getValue ( "fieldName" ) ;
event. setValue ( "fieldName", value ) ;
You can also register send and receive events separately (even using lambdas):
Code (Java):
eventManager.
registerPacketSendListener
(pluginInstance, event
->
{
// code
} ) ;
eventManager. registerPacketReceiveListener (pluginInstance, event -> {
// code
} ) ;
// code
} ) ;
eventManager. registerPacketReceiveListener (pluginInstance, event -> {
// code
} ) ;
Banning a word:
Spoiler: Banning a word from chat
Code (Java):
public
class MainClass
extends JavaPlugin
{
@Override
public void onEnable ( ) {
PacketEventManager eventManager = PacketInjectorPlugin. getInstance ( ). getPacketInjectorAPI ( ). getEventManager ( ) ;
eventManager. registerPacketReceiveListener ( this, event -> {
if (event. getPacketName ( ). equals ( "PacketPlayInChat" ) ) {
String message = ( String ) event. getValue ( "a" ) ; // Might change between mc versions
if (message. contains ( "bannedWord" ) ) {
event. setCancelled ( true ) ;
event. getPlayer ( ). sendMessage ( "§cDon't swear!" ) ;
}
}
} ) ;
}
}
@Override
public void onEnable ( ) {
PacketEventManager eventManager = PacketInjectorPlugin. getInstance ( ). getPacketInjectorAPI ( ). getEventManager ( ) ;
eventManager. registerPacketReceiveListener ( this, event -> {
if (event. getPacketName ( ). equals ( "PacketPlayInChat" ) ) {
String message = ( String ) event. getValue ( "a" ) ; // Might change between mc versions
if (message. contains ( "bannedWord" ) ) {
event. setCancelled ( true ) ;
event. getPlayer ( ). sendMessage ( "§cDon't swear!" ) ;
}
}
} ) ;
}
}
Commands:
The plugin comes with a packet logger which can print every packet (or only certain packets) to the console. It is managed using the following commands:
Spoiler: Commands
The filter gives you the power to exclude or to include only certain packets from being print. The filter subcommands are the following:
Code (YAML):
# Starts the packet logger
/packetinjectorapi packetlogger start
# Stops the packet logger
/packetinjectorapi packetlogger stop
# Prints a message with the status of the packet logger (enabled|disabled)
/packetinjectorapi packetlogger status
# The filter subcommand allows to select the packets to be printed
# More on this down below
/packetinjectorapi packetlogger filter <allow|deny|list|reset|clear> ...
/packetinjectorapi packetlogger start
# Stops the packet logger
/packetinjectorapi packetlogger stop
# Prints a message with the status of the packet logger (enabled|disabled)
/packetinjectorapi packetlogger status
# The filter subcommand allows to select the packets to be printed
# More on this down below
/packetinjectorapi packetlogger filter <allow|deny|list|reset|clear> ...
Code (YAML):
# Add, remove, clear or reset to default the list of allowed packets
# Allowed packets are the only ones to be printed to the console, except when they are also denied
/packetinjectorapi packetlogger filter allow <add|remove|clear|reset> ...
# Add, remove, clear or reset to default the list of denied packets
# Denied packets are not printed to the console
# By default, the deny list contains some packets to prevent the flooding of the console, run the "clear" subcommand if you need those packets
# The list of default denied packets can be seen using the "list" filter subcommand or can be found at this link:
# https://github.com/frengor/PacketInjectorAPI/blob/main/src/main/java/com/fren_gor/packetInjectorAPI/Commands.java#L50
/packetinjectorapi packetlogger filter deny <add|remove|clear|reset> ...
# Lists the allowed and denied packets
/packetinjectorapi packetlogger filter list
# Resets the allowed and denied lists to their default values
/packetinjectorapi packetlogger filter reset
# Clears the allow and deny lists
/packetinjectorapi packetlogger filter clear
# Allowed packets are the only ones to be printed to the console, except when they are also denied
/packetinjectorapi packetlogger filter allow <add|remove|clear|reset> ...
# Add, remove, clear or reset to default the list of denied packets
# Denied packets are not printed to the console
# By default, the deny list contains some packets to prevent the flooding of the console, run the "clear" subcommand if you need those packets
# The list of default denied packets can be seen using the "list" filter subcommand or can be found at this link:
# https://github.com/frengor/PacketInjectorAPI/blob/main/src/main/java/com/fren_gor/packetInjectorAPI/Commands.java#L50
/packetinjectorapi packetlogger filter deny <add|remove|clear|reset> ...
# Lists the allowed and denied packets
/packetinjectorapi packetlogger filter list
# Resets the allowed and denied lists to their default values
/packetinjectorapi packetlogger filter reset
# Clears the allow and deny lists
/packetinjectorapi packetlogger filter clear
