GhostReplay

GhostReplay lets you record your exact in-game inputs and replay them as a macro later.

What It Does

Records keyboard + mouse input

Replays movement with tick-accurate precision

Designed for movement testing, speedruns, and experiments

Fully client-side (no server install needed)

Use Cases

Practice parkour and speedrun routes

Debug movement mechanics

TAS-style experimentation (without going full NASA)

Features

Fabric client mod

Works on Minecraft 1.21.4-11

Lightweight & performance-friendly

Modular system (easy to expand later)

Important Notes

Client-side only

Not a cinematic camera replay

Still under active development, expect updates

Notes for Coders and Nerds

• Build time: ~20 Hours
• Tested for player movement, camera movement, sprinting, sneaking (although glitched, hopefully an easy patch), and block placement/destruction.
• Does not replay anything done within a GUI, eg, Crafting Tables, Inventory, and Furnaces.
