inject
A library for making injecting into Netty easier!. Free Minecraft Java mod for 1.21, 1.21.1, 1.21.2.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
inject
Inject is a simple server-side library to allow developers to inject into Netty easier.
Example
This uses the HttpInjector class to respond to HTTP requests to the Minecraft
server.
class MyEpicHttpInjector extends HttpInjector {
@Override
public HttpByteBuf intercept(ChannelHandlerContext ctx, HttpRequest request) {
HttpByteBuf buf = HttpByteBuf.httpBuf(ctx);
buf.writeStatusLine("1.1", 200, "OK");
buf.writeText("Hello, from Minecraft!");
return buf;
}
}
Registration
For Fabric, use the InjectFabric class:
public class MyMod implements ModInitializer {
@Override
public void onInitialize() {
InjectFabric.INSTANCE.registerInjector(new MyEpicHttpInjector());
}
}
For Spigot, Paper and derivatives, use the InjectSpigot class:
public class MyPlugin extends JavaPlugin {
@Override
public void onEnable() {
InjectSpigot.INSTANCE.registerInjector(new MyEpicHttpInjector());
}
}
This will register an HTTP injector which will respond with Hello, from Minecraft!
to any HTTP request to the Minecraft port.
$ curl http://localhost:25565
Hello, from Minecraft!
