World of Tanks - Replay data extract

1. Description

The package can extract only the metrics data from World of Tanks replays. It does not access any data such as tank positions or chat.

Data can be extracted only from replays in which the player has waited until the end of the battle. If the player has quit the battle after dying and the battle was not ended, then only the battle metadata is available (which does not contain any battle performance / credits / xp data).

The replays should be set to be "all" collected and not "last" one recorded.

All data extracted can be saved to a local sqlite database.

2. Usage

pip install wotreplay

The package provides the possibility of exploring the data contained within one replay or process all replays in a directory and store the data in a local database.

from wotreplay import ReplayData
replay = ReplayData(file_path='path_to_replay/replay_file.wotreplay',
                     db_path='', db_name='', load=False)

print(replay.battle_metadata)
print(replay.battle_performance)
print(replay.common)
print(replay.battle_frags)
print(replay.battle_economy)
print(replay.battle_xp)

Process all the replay files and store the results in the database

from wotreplay import ProcessReplays

ProcessReplays.process_all(replay_dir='/path/to/replay/dir', 
                           db_path='path/where/to/save/the/database', 
                           db_name='wotreplay')

This will process the replays sequentially.

Note: Once a replay has been processed and added to the database, it will not be processed again to avoid data duplication.

3. Compatibility

The replays from the following client versions have been tested.

No replays before 0.9.21 have been tested due to lack of replays available.

4. Data Taxonomy

Examples of data retrieved:

• Battle metadata: Battle Metadata Fields
• Battle performance: Battle Performance Fields
• Common: Common Data Fields
• Battle frags: Battle Frags Fields
• Battle economy: Battle Economy Fields
• Battle xp: Battle XP Fields

5.Access and rights

6.To Do

The extraction of data from replays is more or less complete. There are a few features to be created in the future to create the aliases of tank names and maps.
