Recommended Posts

I created a tag as described in the forge doc,

when I try to check whether a block is included in this tag, I get an error

this is my tag

this is my Tag Class

and that's the block class  in which I use the tag

 

and that's the error i get:

// Surprise! Haha. Well, this is awkward.

    • Here is my configuration: % java -version java version "18.0.2" 2022-07-19 Java(TM) SE Runtime Environment (build 18.0.2+9-61) Java HotSpot(TM) 64-Bit Server VM (build 18.0.2+9-61, mixed mode, sharing) forge-1.19-41.1.0-mdk on macOS Monterey 12.5 I ran the command: ./gradlew genEclipseRuns and was hoping it will generate the Eclipse project files for me. The run log is at https://gist.github.com/arun-gupta/06b983a6976b4c0a0f510d0dc225ddd3 and the generated directory structure is at https://gist.github.com/arun-gupta/3f5bfc70ec5d3d903b0f97d42840abda. In previous versions (1.12-ish), it used to generate an eclipse directory but 1.19 does not seem to have it. I tried opening the top-level forge directory but Eclipse does not recognize it as a project as well. How do I open this project in Eclipse now?  
    • I didn't put in credentials, I used it only for testing installing forge. But still the problem mentioned above.
    • I am trying to use Forge 1.18.2, I have checked my firewall, redownloaded Forge, deleted the fml.toml file (which keeps reappearing) and looked at countless help pages. I am just trying to download and use forge so that I can play with my friends and it will not download. It tells me there may be an issue with the Java runtime config and that the exit code is one, and I have copied the exit code.   
    • Okay, i think i understand but im getting issues, i create another packet to sync entity to another players like this package com.naim.belloto.networking.packet; import com.naim.belloto.networking.handler.ClientSyncHandler; import net.minecraft.client.Minecraft; import net.minecraft.network.FriendlyByteBuf; import net.minecraftforge.api.distmarker.Dist; import net.minecraftforge.fml.DistExecutor; import net.minecraftforge.network.NetworkEvent; import java.util.Objects; import java.util.function.Supplier; public class ClientSyncPacket { public ClientSyncPacket() { } public ClientSyncPacket(FriendlyByteBuf buf) { } public void toBytes(FriendlyByteBuf buf) { } public boolean handle(Supplier<NetworkEvent.Context> ctx) { NetworkEvent.Context context = ctx.get(); context.enqueueWork(() -> { assert Minecraft.getInstance().player != null; int idplayer = Minecraft.getInstance().player.getId(); DistExecutor.unsafeCallWhenOn(Dist.CLIENT,() -> () -> ClientSyncHandler.handlePacket(ctx, idplayer)); }); return true; } } And in the handler: public class ClientSyncHandler { public static boolean handlePacket(Supplier<NetworkEvent.Context> ctx, int idPlayer) { Minecraft.getInstance().level.getEntity(idPlayer); return true; } } But is not working ://
