World of Tanks Replay Parser

What?

This program aims to decode replay files and convert them into more accessible formats such as an image or json files. Which may be uses in other programs. The alternative project wotreplay-viewer implements a small HTML5 viewer for the JSON data.

When using the json output option, the replay is decoded into a list of packets, in the same way it is described in the replay file. The following information can be extracted from from the replay.

Position
Health
Tanks being tracked
Tanks getting shot or killed
Hull Orientation
Messages

Examples

Output type PNG

Displays a summary of the battle on a map, green lines are your own team, red lines the enemy team, and blue is the recording player.

Output type GIF

Displays an animation of the battle on the map.

Output type HEATMAP

Displays a heatmap of the positions of the tanks in the battle (for both teams combined)

Output type Team Heatmap

Displays a heatmap of the positions of the tanks in the battle (colored by team)

Output type Team Heatmap (Soft)

Displays a heatmap of the positions of the tanks in the battle (colored by team), with some smoothing applied.

Output type Class Heatmap

Displays a heatmap of the positions following user defined classes.

Dependencies

OpenSSL
Boost (Complete)
LibPNG
LibXML2
libjson-cpp (included in the source, from http://jsoncpp.sourceforge.net/)
Intel Threading Building Blocks (Optional)

Compiler Support

GCC (>= 4.7)
CLANG

Compile

Unix

git clone https://github.com/evido/wotreplay-parser.git
cd wotreplay-parser
cmake .
make

You may need to specify the include directory for LibXML2 using the CMAKE variable INCLUDE_DIRECTORIES. This can be done as following.

cmake -DINCLUDE_DIRECTORIES="/usr/include/libxml2" .

Debian like Linux

You may need to install the following packages in order to compile successfully (tested ok on an Ubuntu 20.04 install):

sudo apt-get install build-essential libboost-all-dev git cmake libpng-dev libcrypt-dev libssl-dev libgd-dev libtbb-dev

Win32

Binaries can be built using VS2019 (using MSVC 2015 build tools).

ZLIB / PNG and GD can be found here prebuilt
QT 5.9.8

Data

To use this software you need some data extracted from World of Tanks, this data contains some elements to draw the mini map, the actual minimaps and the arena definitions. I have prepared an archive which is available here. This should be available in the root folder (see next paragraph).

Run

Decode Replays

The program can be used to convert wotreplay files to images or json files.

wotreplay-parser --parse --root <working directory> --type <output type> --input <input file> --output <output file>

output type can be png, json, team-heatmap, heatmap and class-heatmap it is possible to specify multiple types (e.g. png,json), when using multiple types the output file specification will be appended with a suffix (.png, .json and _heatmap.png)
output is optional, the program will then write to stdout
input and output are relative to root
root should contain a folder maps with the images to maps and the arena definitions

Create Heatmaps

The program can be used to create heatmaps for a directory of replays

wotreplay-parser --parse --root <working directory> --type heatmap --input <input directory> --output <output directory>

input directory is the directory containing all the replays (relative to root, only first level will be scanned)
output directory images will be written to this directory, for each map / game mode an output file will be generated (relative to root)
root should contain a folder maps with the images to maps and the arena definitions
size specifies the output dimensions of the generated image (for image output types)
rules specify drawing rules to be used for output type class-heatmap (surround the argument with quotes to avoid the program interpreting it as seperate arguments)

Create Minimaps

The program can also be used to create all the minimaps for usage in wotreplay-viewer.

wotreplay-parser --create-minimaps --root <working directory> --output <output directory>

root the working directory containing the necessary data
output the output directory relative to the root directory

Rules

The syntax of drawing rules is as follows (EBNF syntax)

rules = rule *(';' rule)
rule = color ':=' expression
expression = operation *(logical_operator operation)
operation = operand comparison operand
operand = symbol | value
logical_operator = 'and' | 'or'
comparison = '=' | '!=' | '>' | '<' | '>=' | '<='
color = '#' hex{6}
symbol = 'player' | 'clock' | 'team' | 'tank_name' | 'tank_country' | 'tank_tier' | 'tank_icon' | 'tank_class'
value = ''' +(digit | alpha | '_' | '-' ) '''

Each packet is evaluated using the defined rules and assigned a class (first match), which will be used in the resulting heatmap.

Packet Overview

Type 0x03

This packet is related to the spotting of tanks, it will occurr together with packet type 0x05 when the tank appears for the user (each time).

type: the type of the packet
clock: the timestamp of the packet

Type 0x05

See packet type 0x03

Type 0x07

Sub Type 0x05

This packet seems to be a health update which is sent relatively frequently, it only contains the following properties.

type: the type of the packet
clock: the timestamp of the packet
player_id: the subject of the health update
sub_type: the sub-type of the packet
health: the health of the referenced player

Sub Type 0x07

This packet seems to be sent when a player's tracks are repaired, it also indicates which track is still destroyed.

type: the type of the packet
clock: the timestamp of the packet
player_id: the subject of the track status
sub_type: the sub-type of the packet
destroyed_track_id: the id of the track that is still destroyed, possible values here are 0x00 (tank is not tracked), 0x1D (left track) and 0x1E (right track)

Type 0x08

Sub Type 0x01

This packet indicates a player doing damage to another player and will most likely be accompanied by another packet indicating the type of damage such as Sub Type 0x05

type: the type of the packet
clock: the timestamp of the packet
player_id: the subject of the track status
sub_type: the sub-type of the packet
source: player causing the damage
health: new health of the player

Sub Type 0x05

This packet indicates that a player was shot by another player. When this is not accompanied by a damage packet, the player bounced the shell.

type: the type of the packet
clock: the timestamp of the packet
player_id: the subject of the track status
sub_type: the sub-type of the packet
source: source of the shell

Sub Type 0x0B

Most likely the indicator of a module being damaged.

type: the type of the packet
clock: the timestamp of the packet
player_id: nonsense?
sub_type: the sub-type of the packet
source: player dealing damage to the moduel
target: player receiving the damage

Sub Type 0x11

Indicator that a shot was fired by a player.

type: the type of the packet
clock: the timestamp of the packet
player_id: the subject of the track status
sub_type: the sub-type of the packet

Sub Type 0x17

Unclear.

type: the type of the packet
clock: the timestamp of the packet
player_id: the subject of the track status
sub_type: the sub-type of the packet
target: player receiving the damage

Type 0x0A

This is the most frequent type of packet, it tells the player about the positions of any other player.

type: the type of the packet
clock: the timestamp of the packet
player_id: the subject of the track status
position: the sub-type of the packet
hull_orientation: the sub-type of the packet

Type 0x23

This packet contains a message sent to the battlelog during the game. The owner information is encoded inside the message.

<font color='#DA0400'>SmurfingBird[RDDTX] (VK 36.01 H)&nbsp;:&nbsp;</font><font color='#FFFFFF'>so far so good</font>

type: the type of the packet
clock: the timestamp of the packet
message: a html encoded message

Type 0x20

This packet indicates that a player's tank was tracked.

type: the type of the packet
clock: the timestamp of the packet
player_id: the subject of the track status
sub_type: the sub-type of the packet
alt_track_state: indicates if the tank is tracked using values 0xF0 (not tracked) or 0xF6 (tracked)
destroyed_track_id: the id of the track that was destroyed destroyed, possible values are 0x1D (left track is destroyed) and 0x1E (right track is destroyed).
