README

A PocketMine-MP library to record and replay games. You can find an example of how to use this library in a plugin here. The library supports reversed watching, world changes, multiple world recording and has an included event log for stuff like deaths or significant game events.

NOTE

Using a replay system like this can cause performance issues, especially if you record multiple worlds at once, which i would NOT recommend.

This is a Network based Replay API, means it's not supposed to be used as a recorder and replayer at once on the same server.

However, if you have any issues, ideas or feature requests, just create an issue.

API

Recorder

Recording

To handle the replay recording use the functions in the RecordHandler class.

public function record(RecordSettings $settings, World $world, GameDetails $details): Recorder;

public function stopRecording(World $world, ?Closure $onComplete = null): void;

public function isRecording(World $world): bool;

public function getRecorder(World $world): ?Recorder;

public function getRecordings(): array;

public function changeRecordingWorld(Recorder $recorder, World $world): void;

Actions

To add your own action, use the ActionHandler.

ActionHandler::getInstance()->registerAction(
    new EntitySigmaAction()
);

class EntitySigmaAction extends EntityAction{
    protected const ID = CustomActionIds::ENTITY_SIGMA; //like 21 or something

    private string $sigma;

    public static function create(int $entityId, string $sigma): self{
        $action = new self();
        $action->entityId = $entityId;
        $action->sigma = $sigma;
        return $action;
    }

    public function serialize(BinaryStream $stream): void{
        parent::serialize($stream);
        $stream->putString($this->sigma);
    }

    public function deserialize(BinaryStream $stream): void{
        parent::deserialize($stream);
        $this->sigma = $stream->getString();
    }

    public function handle(Replay $replay): void{
        if (!$entity = $replay->getEntity($this->entityId)) return; //don't ask me how tf this is even possible
        $entity->setDisplayName($this->sigma);
    }
    
    public function handleReversed(Replay $replay): ?Action{
        return self::create($this->entityId, $replay->getEntity($this->entityId)?->getDisplayName());
    }
}

$recorder->addAction(EntitySigmaAction::create($entity->getId(), "Absolute SIGMA!!!!"));

Event Log

To add your own events to a replay, for example a "bed break" event for bed wars, use the EventLogHandler.

EventLogHandler::getInstance()->registerEventLog(
    new BedBreakEvent()
);

class BedBreakEvent extends EventLog{
    protected const ID = CustomEventLogIds::BED_BREAK_EVENT; //like 3 for example

    private string $playerName;
    private string $team; //could be "red" or "blue" or whatever
    private int $playerId;

    public static function create(Player $player, string $team): self{
        $data = new self();
        $data->playerName = $player->getDisplayName();
        $data->playerName = $team;
        $data->playerId = $player->getId();
        return $data;
    }

    public static function getName(): string{
        return "beds";
    }

    public static function getTickOffset(): int{ //This is the time offset you get teleported to before the event happened (like 4 * 20 is 4 seconds before they broke the bed)
        return 4 * 20;
    }

    public function getDisplayData(): string{
        return "§c" . $this->playerName . "§8 broke a bed of team§6 " . $this->team);
    }

    public function serialize(BinaryStream $stream): void{
        $stream->putString($this->playerName);
        $stream->putString($this->team);
        $stream->putInt($this->playerId);
    }

    public function deserialize(BinaryStream $stream): void{
        $this->playerName = $stream->getString();
        $this->team = $stream->getString();
        $this->playerId = $stream->getInt();
    }

    public function handle(Replay $replay): void{
        $replay->getWatcher()->teleport($replay->getEntity($this->playerId)->getPosition());
    }
}

$recorder->addEventLog(new BedBreakEvent($player, $team));

Replayer

Replaying

To handle the replay watching use the Replay events and the functions in the Replay class.

    public static function play(ReplaySettings $settings, Player $player, ReplayInformation $information): void;

    public function end(): void;

    public function skip(ReplayPlayDirection $direction, int $ticks): void;

    public function skipToTick(int $tick): void;

    public function getPlayDirection(): ReplayPlayDirection;

    public function setPlayDirection(ReplayPlayDirection $playDirection): void;

    public function getSpeed(): float;

    public function setSpeed(float $speed): void;

    public function isPaused(): bool;

    public function togglePaused(): bool;

    public function getEventLogs(): array;

    public function getWatcher(): Player;

    public function getWorld(): ?World;

    public function getEntity(int $entityId): ?ReplayEntity;

    public function getEntities(): array;

    public function getSettings(): ReplaySettings;
