Overview

A replay is a file stored within the game save, containing any information needed to repeat (replay) a game from start, in a movie-like fashion. This feature is to allow players to view how their world came to be.

Creating & playing a replay

Replays can be automatically generated as the map is played, behind the scenes. To enable this, the "Record replay information" option needs to be checked upon creation of the map in the map settings. Replays have rather strong limitations, see below.

Playing a replay will play back in chronological order the actions taken in the world, as if the player was recording. The speed of playback can be increased or decreased to fine-tune the viewing experience.

To play replays, from the main menu go to Single Player -> Load game, then find the ▶ Start replay button in the upper right.

The replay GUI

A simple control GUI is available to control replay playback:

1. Pause/play the replay 
2. Slow down playback 
3. Speed up playback 
4. Playback position

In multiplayer replays it is also possible to change the viewpoint player.

Limitations

  • Replays for worlds created in older versions cannot be played. Downgrading is needed to view the replay.
  • Adding/removing mods to the save will also break the replay.
  • Although the replay option is part of the map settings, it is not saved to map exchange strings, hence it needs to be enabled manually after importing an exchange string.
  • Playback view is locked to the character in singleplayer.
  • There is no way to skip ahead, the entire replay must be watched up until the point of interest.
  • Re-winding (A.K.A. Going backwards in time ) is not possible.

Advanced Features

  • The game can be saved at any time during playback, thus it is possible to play again from any time during the replay.
  • Changing the script files inside the save will not invalidate the replay. This can be used e.g. to collect data or screenshots in the background as the replay runs.
