ServerReplay

Server Replay

English | 中文

A completely server-side implementation of Replay Mod and Flashback, this mod allows you to record multiple players that are online, or chunk areas, on a server at a time. This will produce replay files which can then be used with the replay mod or flashback for rendering.

Why Server-Side?

Compared to the client Replay Mod or Flashback recording server-side has many benefits:

• The ability to record static chunks.
• You can specify the exact chunk size (not bound by server view distance).
• The recorded chunks may be unloaded without affecting the replay.
• No chunk flickering (from unloading and loading the chunks).
• The chunks will also not be loaded by the recorder (like, for example, PCRC).
• Pause and resume the recorders based on whether the chunks are being loaded or whether

there are players in the chunks

• The ability to record individual players.
• Players aren't required to install replay mod or flashback.
• You can record all POVs at once.
• Recordings can be automated using the configuration.
• Recordings can be started at anytime by operators (or anyone with permissions).

However, there are also some downsides and known issues:

• Some features are not recorded by chunk recordings, e.g. custom boss bars.
• Player recordings may not be 100% consistent with the client Replay Mod or Flashback.
• ServerReplay isn't really designed for heavily modded servers.

More complex mods that implement their own packets may not be compatible.

• If you encounter any compatability issues, please submit an issue.

Usage

This mod requires the fabric launcher, fabric-api, and fabric-kotlin.

There are two ways of recording on the server, you can either configure it to follow and record players from their view. Alternatively, you can record a static area of chunks.

Quick Start

> Note: > This documentation is for the latest version of the mod, for older > versions of the mod please see the other branches

This section of the documentation will briefly guide you through a basic setup. As well as containing some important information.

Players

To record a player on your server you can run /replay start players <player(s)>, for example:

/replay start players senseiwells
/replay start players @a
/replay start players @a[gamemode=survival]

Player recorders are tied to the player and will record at the servers view distance.

If the player leaves or the server stops, the replay will automatically stop and save.

Alternatively if you wish to stop the recording manually you can run /replay stop players <player(s)> <save?>, using this command you can also stop a recording without saving it, for example:

/replay stop players senseiwells
/replay stop players @r
/replay stop players senseiwells false
