Obtaining Player State

[Rishabh]

Hey all,

I was trying to play around with the network protocol. How can I extract the state of the game currently? I couldn't seem to find this part in the source. I want to be able to send my state to the other player without hashing it.

Thanks in advance.

What do you want to achieve exactly? Just disable hashing to improve performance?

You can check out how the simulation state is serialized for the hashing itself, see CComponentManager::ComputeStateHash , as the code comment says:

Quote

// Hash serialization: this includes the minimal data necessary to detect
// differences in the state, and ignores things like counts and names

// If 'quick' is set, this checks even fewer things, so that it will
// be fast enough to run every turn but will typically detect any
// out-of-syncs fairly soon

For the full simulation state serialization / deserialization you can examine the save / load game mechanics, see SavedGame.cpp

Isn't the game state in one of these objects?

https://github.com/0ad/0ad/blob/9c792c327af49702eb146d8551235ebc650fd561/binaries/data/mods/public/simulation/ai/common-api/shared.js

baseAI uses it like this

this.gameState = sharedAI.gameState[this.player];

I think its a pretty elaborate js object with many nested dictionaries and somewhere in the simulation code gets updated each player's turn.
