Main Page and Old Engine/JAGGRAB Protocol: Difference between pages

Revision as of 23:29, 6 September 2021

Resources

Basics

JAGGRAB runs on port 43595, it is used as a fallback when a resource over HTTP is not available. It downloads the necessary BZip2 archives to bootstrap the client. They are then stored in main_file_cache.idx0.

This protocol is essentially HTTP/0.9, see: https://www.w3.org/Protocols/HTTP/AsImplemented.html. The main difference is the client closes the connection, not the server. If you close the connection from the server the client will raise an end of stream exception. The method is also JAGGRAB and not GET.

The remaining model, animation, midi, and map data is loaded on demand in a separate protocol.

URIs

"crc" + rand() + "-" + clientVersion

40-byte CRC/hash of all the idx0 archives.

- 36-byte CRCs: 9 archives * 4 byte CRC

- 4-byte hash.

"title" + crcs[1]

Title screen content.

"config" + crcs[2]

Resource definitions (NPCs, Objects, Items, etc).

"interface" + crcs[3]

In-game interfaces.

"media" + crcs[4]

2D graphics.

"versionlist" + crcs[5]

Contains CRCs, versions, and index data for idx1-4 files.

"textures" + crcs[6]

3D graphics.

"wordenc" + crcs[7]

Word encoding (censoring) data.

"sounds" + crcs[8]

.WAV sounds.
