All Name PacketHook (0x98)

[Danielle]

Not sure when this was added to the 2D client, but it exists in at least version 4.0.6a.

Here is the code (you can download it below as well)

NOTE: This feature is now built into all POL versions/builds after "097-2007-01-04-RC2-Coregina". For previous versions/builds you'll still need this packet hook. Regardless though, using the packet hook will allow you greater customization on how this feature is handled. You decide.

//
//  Name:    All Names Hook
//  Version: 1.0
//  Author:  Danielle Elora
//
//  Purpose: Responds to the "all names" packet (0x98) sent by the client when pressing Ctrl+Shift.
//
//	PACKET DETAILS:
//
//	BYTE[1] cmd 
//	BYTE[2] blocksize 
//	BYTE[4] ID 
//	If (server-reply) 
//	BYTE[30] name (0 terminated)
//
//	Client request has 7 bytes, server-reply 37. Client already knows item names, and only
//	askes for mobiles names, hence ID is always a mobile serial.

  // Since the core doesn't understand this packet, might as well block it from the core anyway.
