Replay Fight

Replay Fight is a lightweight bridge between Epic Fight and the replay tools Replay Mod and ReForgedPlay. Without it, combat animations from Epic Fight can display incorrectly when a recording is played back. The patch changes how those animations are handled during replay so they render as they did live. It is a simple patch rather than a feature set, and it does not add content of its own.

The mod needs Epic Fight as a required dependency and runs on client and server, so both the server and every player need it. Files exist for 1.20.1 and 1.21.1, with 1.0.0 as the latest build for each loader. The code is open source under the GNU General Public License v3.0 or later. Some addons are supported, though the author notes that testing an addon directly is the way to confirm it. Installation is a drop-in step: place the jar in the mods folder and no configuration is needed.

The underlying problem is that Epic Fight and other content mods change the registry IDs that the game assigns to items, blocks and entities. A replay file stores the IDs that were in use when it was recorded, so installing or removing content-heavy mods afterwards can make replays show the wrong objects. The author advises creating a new world only after the modpack is finalized, avoiding adding or removing large content mods mid-playthrough, and reviewing replays against the same mod set they were recorded with.
