### Client-side and server-side ViaVersion implementation for Fabric

Allows the connection to/from different Minecraft versions on your Minecraft client/server (LAN worlds too)

This mod can be installed on 1.14.4, 1.15.2, 1.16.5, 1.17.1, 1.18.2, 1.19.4, 1.20.1, 1.20.4, 1.20.6, 1.21.4 with Fabric Loader.

The `legacy` branch also supports Legacy Fabric 1.8.9 and 1.12.2 versions.

If you are using the latest Minecraft version and care about the gameplay being more enjoyable/functional, you may want to 

check [ViaFabricPlus](https://modrinth.com/mod/viafabricplus) out. See the [differences](#viafabricplus) between ViaFabric and ViaFabricPlus.

Note: ViaVersion is designed for Vanilla Minecraft servers. It probably will not work with modded registry entries or

registry synchronization (fabric-registry-sync mod).

## ViaVersion

### How can I install ViaBackwards/ViaRewind/ViaAprilFools?:

- Just drop them into mods folder. Make sure you are using versions compatible with the ViaVersion version you are

  using.

### What versions can ViaVersion, ViaBackwards, ViaRewind and ViaAprilFools translate?:

- **With [ViaVersion](https://viaversion.com)**:

  Your server can accept newer versions. Your client can connect to older versions.

- **Adding [ViaBackwards](https://viaversion.com/backwards) (and

  optionally [ViaRewind](https://viaversion.com/rewind))**:

  Your server can accept older versions. Your client can connect to newer versions.

- **Adding [ViaAprilFools](https://viaversion.com/aprilfools)**: Your server can accept April Fools versions.

  Note: When using ViaFabric for versions older than 1.17, you need [Java 8 builds](https://ci.viaversion.com/)

- Server-side: See https://viaversion.com/

- Client-side:

|                       | 1.8.x | 1.9.x | 1.10-1.20.x | 1.21.x |

|-----------------------|-------|-------|-------------|--------|

| 1.14.4-1.20.6 clients | ✓     | ✓     | ✓           | ⟲      | ⟲   ⟲ | ⟲ | ⟲ | ⟲ | ⟲ |

| 1.21.4 client         | ✓     | ✓     | ✓           | ✓      | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |

✓ = [ViaVersion](https://viaversion.com) ⟲ = [ViaBackwards](https://viaversion.com/backwards) ⏪

= [ViaRewind](https://viaversion.com/rewind)

*Note: 1.7.x is not supported in ViaFabric - 1.9.x, 1.10.x, 1.11.x, and 1.13.x may cause problems when visiting such servers in client-side mode.*

### Can ViaVersion, ViaBackwards and ViaRewind support snapshots?:

- Check https://viaversion.com/donate for getting early access to snapshots. You can use the preview ViaVersion builds with ViaFabric by 

  putting them in the mods' folder. During Minecraft updates there will be usual a branch on this repository with the updated ViaFabric.

## Alternatives

### Client-side:

- [ViaForge](https://modrinth.com/mod/viaforge): Clientside Implementation of ViaVersion for Forge.

- [ViaFabricPlus](https://modrinth.com/mod/viafabricplus): Fabric mod for the latest Minecraft version with QoL fixes and enhancements to the gameplay.

- [ClientViaVersion](https://github.com/Gerrygames/ClientViaVersion): Discontinued 5zig plugin.

- [multiconnect](https://www.curseforge.com/minecraft/mc-mods/multiconnect): Discontinued Fabric mod for connecting to older

  versions: down to 1.11 (stable) and 1.8 (experimental).

### Server-side:

- [ViaVersion](https://viaversion.com): Plugin for Velocity and Paper/Bukkit (and optionally also Sponge/BungeeCord). 

- [ProtocolSupport](https://github.com/ProtocolSupport/ProtocolSupport): Discontinued Bukkit plugin for older client versions (down to 1.4.7).

### Standalone proxy:

- [ViaProxy](https://github.com/ViaVersion/ViaProxy): Standalone ViaVersion proxy with ViaBackwards, ViaRewind and ViaLegacy,

  allowing you to connect to a wide range of versions (down to classic versions) with your modern client (1.7.2+). Supports online mode.

- [VIAaaS](https://github.com/ViaVersion/VIAaaS): Standalone ViaVersion proxy with ViaBackwards and ViaRewind, allowing

  you to connect without a mod installed on your client. Supports online mode.

- [DirtMultiversion](https://github.com/DirtPowered/DirtMultiversion): Discontinued Proxy allowing to connect down to Beta 1.3 with

  newer Minecraft client versions.

### Cool things to try:

- [Geyser](https://geysermc.org/): Plugins, Fabric mod and a standalone proxy for allowing Bedrock Edition on Java

  Edition servers.

- [PolyMc](https://github.com/TheEpicBlock/PolyMc): Fabric mods which translates modded items and blocks, allowing

  vanilla to connect using resource packs.

## Commands

### Commands:

- There're 3 server-side alias ``/viaversion``, ``/vvfabric`` and ``/viaver``, and a client-side command

  ``/viafabricclient`` for Minecraft 1.14+ (OP permission level 3 is required for these commands, received

  by [Entity Status Packet](https://wiki.vg/Entity_statuses#Player))

## Configs

### Configuration:

- ViaVersion configuration is available at ``.minecraft/config/viafabric/viaversion.yml``

- ViaFabric configuration is at ``.minecraft/config/viafabric/viafabric.yml``

### How can I disable client-side ViaFabric?:

- You can disable it in the menu or by setting global protocol version to -1 (this will keep per-server translations

  still enabled)

### How to use protocol detection?:

- For using globally, set the protocol to AUTO or -2. For using in a specific

  server: ``ddns.example.com._v-2.viafabric``

- The protocol detector will try to ping with the client native protocol version, differently than multiconnect which

  uses -1 version, which may detect the native server version.

### How can I set the version for specific servers?:

- Append ._v(VERSION).viafabric.

- Examples: ``minigame.example.com._v1_8.viafabric``, ``native.example.com._v-1.viafabric``

  , ``auto.example.com._v-2.viafabric``

## ViaFabricPlus

### Does it work with ViaFabric:

- No, ViaFabric cannot be used with ViaFabricPlus.

### Differences with ViaFabricPlus:

|                                  | ViaFabric                                       | ViaFabricPlus                                                   |

| How does it work?                | Modifying packets at network code               | Modifying client code more deeply                               |

| Triggering anti-cheats           | Very likely                                     | Mostly not                                                      |

It cannot be guaranteed that this mod is allowed on specific servers as it can possibly cause problems with anti-cheat plugins.\
