Configuration file is under ${minecraftDir}/config/hybridfix.cfg

How To (Server Admins)

Download HybridFix and its dependencies(MixinBooter and ConfigAnyTime) from CurseForge, drop HybridFix into ${minecraftDir}/mods folder.

HybridFix can be also installed on the client, some client-side fixes and optimizations will apply.

How To (Developers)

If you are developing mods, you can import HybridFix from curse maven:

Gradle(Groovy DSL):

implementation fg.deobf("curse.maven:hybridfix-1166614:{latest_artifact_id}")

If you are developing plugins, you can import HybridFix jar directly:

Maven:

<dependency>
    <groupId>io.wdsj</groupId>
    <artifactId>hybridfix</artifactId>
    <version>{latest_version}</version>
    <scope>system</scope>
    <systemPath>PATH-TO-JAR</systemPath>
</dependency>

Gradle(Groovy DSL):

compileOnly files("PATH-TO-JAR")

APIs are located at io.wdsj.hybridfix.api and io.wdsj.hybridfix.duck.api package.

Plugin Hooks

Thanks to HybridFix internal plugin, we can hook into plugins from Forge side to provide more fixes.

Currently patched plugins:

Plugin ASM patcher

HybridFix uses ASM to inject into plugin classes dynamically at runtime
to resolve plugin compatibility problems with Forge+Bukkit environment.

Currently supported plugins:

  • Residence: Fixes compatibility with Residence 6.0.0.0+.
  • Universal: Redirects InventoryView INVOKEINTERFACE call to INVOKEVIRTUAL.

About FakePlayers

HybridFix utilizes Forge FakePlayer to fix some grief bugs, the naming logic is [modid-ClassName].

For example, the botania rannuncarpus patch is using the fake player with name [botania-SubTileRannuncarpus].

You can add these names into whitelist/blacklist of your plugins to customize behavior.

Frequently Asked Questions

HybridFix server crashes on startup – what to do?

Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.12.2). You can switch loaders with one click in the panel.

Is HybridFix compatible with forge?

HybridFix officially supports forge for Minecraft 1.12.2. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with HybridFix – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if HybridFix consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
