| Description | The Quake II network protocol is very similar to the QuakeWorld protocol. As in the past, the server to client network packets have the same format as the demo files (Quake II's dm2 files). This would make all forms of bot programming impossible until someone deciphers the checksum routine (which would defeat the purpose of putting the checksum in the first place). The checksum routine for v3.10 and v3.13 has been hacked and is included in this spec. Currently, it appears that for each major release, Id Software will need to change the checksum routine to combat the current hacked version. Also, the checksum not only prevents the creation of proxy bots, but also the creation of autonomous bots. |
