DoomGame

DoomGame is the main object of the ViZDoom library, representing a single instance of the Doom game and providing the interface for a single agent/player to interact with the game. The object allows sending actions to the game, getting the game state, etc. The declarations of this class and its methods can be found in the include/ViZDoomGame.h header file.

Here we document all the methods of the DoomGame class and their corresponding Python bindings implemented as pybind11 module.

Flow control methods

init

C++

bool init()

Python

init() -> bool

Initializes ViZDoom game instance and starts a new episode. After calling this method, the first state from a new episode will be available. Some configuration options cannot be changed after calling this method. Init returns true when the game was started properly and false otherwise.

close

C++

void close()

Python

close() -> None

Closes ViZDoom game instance. It is automatically invoked by the destructor. The game can be initialized again after being closed.

newEpisode

C++

void newEpisode(std::string recordingFilePath = "")

Python

new_episode(recording_file_path: str = "") -> None

Initializes a new episode. The state of an environment is completely restarted (all variables and rewards are reset to their initial values). After calling this method, the first state from the new episode will be available. If the recordingFilePath argument is not empty, the new episode will be recorded to this file (as a Doom lump).

In a multiplayer game, the host can call this method to finish the game. Then the rest of the players must also call this method to start a new episode.

Note: Changed in 1.1.0

replayEpisode

C++

void replayEpisode(std::string filePath, unsigned int player = 0)

Python

replay_episode(file_path: str, player: int = 0) -> None

Replays the recorded episode from the given file using the perspective of the specified player. Players are numbered from 1, If player argument is equal to 0, the episode will be replayed using the perspective of the default player in the recording file. After calling this method, the first state from the replay will be available. All rewards, variables, and states are available when replaying the episode.

void advanceAction(unsigned int tics = 1, bool updateState = true)

Python

advance_action(tics: int = 1, update_state: bool = True) -> None

Processes the specified number of tics, the last action set with setAction method will be repeated for each tic. If updateState argument is set, the state will be updated after the last processed tic and a new reward will be calculated based on all processed tics since last the last state update. To get the new state, use getState and to get the new reward use getLastReward.

makeAction

C++

double makeAction(std::vector<double> const &actions, unsigned int tics = 1)

Python

`make_action(actions: list

This method combines functionality of setAction, advanceAction, and getLastReward called in this sequance. Sets the player’s action for all the next tics (the same action will be repeated for each tic), processes the specified number of tics, updates the state and calculates a new reward from all processed tics, which is returned.

isPlayerDead

C++

bool isAudioBufferEnabled()

Python

is_audio_buffer_enabled() -> bool

Returns true if the audio buffer is enabled.

setAudioBufferSize

C++

void setAudioBufferSize(unsigned int size)

Python

set_audio_buffer_size(size: int) -> None
