Introduction

The Codec class insisde of Zombslib is the main packet decoding/encoding interface. It is what Game uses internally to deal with raw data.

Cryptography

Documentation for ZRCrypto class, as well as the rest of Codec is going to be completed in a later time frame.

Unknowns

In case the RPC mapping, for whatever reason, doesn’t contain a descriptor for an RPC with a given namehash, the following fallbacks are used:

• Rpc name: R_0x{rpc-namehash-hex}
• Rpc parameter name: P_0x{param-namehash-hex}

The same parameter name fallback is used when a descriptor exists but the needed parameter can’t be found in it.

Analgoically, entity map attributes (Tick fields) unaccounted for by Codec.getAttributeName(), use a similar convention:

• Attribute name: A_0x{attr-id-hex}
