About this project
What does Create: Flashback add?
Create: Flashback
If something isn't captured properly in the recording, please rewind it.
A mod that lets you properly record and replay Create's machines (spinning blocks, trains, etc.) with Flashback.
Create machines are sent to the client in a different way than normal mods, so without this mod they show up empty or vanish during replay. This mod fixes that.
Create: Aeronautics Flashback helps you record Create: Aeronautics (Sable) sub-level machines.
Recommend introducing Fix Flashback to fix the bug.
Installation
- Install NeoForge 1.21.1 and Sinytra Connector.
- Install Flashback (download the Fabric 1.21.1 version).
- Put
create_flashback-<version>.jarinto yourmodsfolder. - If you use Create: Aeronautics, also install
create_aeronautics_flashback. - That's it — just record with Flashback as usual.
If you are using the latest versions of Sable and Aeronautics along with Iris Shaders, please use Sodium version 0.8.12-beta.2 and Iris Shaders version 1.8.14-beta.1.
Requirements
- Minecraft
1.21.1 - NeoForge
21.1.x - Flashback
0.30+(via Sinytra Connector) - Create
6.0+ - Sinytra Connector (needed to run Fabric mods like Flashback on NeoForge)
Notes
- This is a client-side mod. It works without being installed on the server. Installing it on the server is also fine.
- Not compatible with ReplayMod. Having both may break recording. Use Flashback instead.
- Not compatible with ServerCoreMod. It may cause rendering to break.
- To record Create: Aeronautics (Sable) sub-level machines, you also need Create: Aeronautics Flashback.
Known incompatible mods
The following mods interfere with Flashback's replay features. If you install them, the corresponding feature stops working. Remove or disable them to use that feature:
| Mod | Feature broken |
|---|---|
| BadOptimizations | Night vision is no longer applied during replays |
| Create: Steam 'n' Rails | Spectator camera stops working |
| Smooth Movement | Time override stops working |
These only affect Flashback's replay features; the rest of the mods work normally.
How it works
- Create contraptions (spinning / moving machines) are sent via a special
advanced_add_entitypayload. This mod includes that data in Flashback's replay snapshot. - Even when you seek (jump to a different point) during playback, the machines are rebuilt from the snapshot, so they display correctly no matter where you start.
- Also supports Sable sub-levels (Create: Aeronautics) when used together with Create: Aeronautics Flashback.
