So how do I do that? It's being done on the server.

Hi, so I was making an item that sends info to the server to do some work, and I want the server to send the client back the results? How do I do that? Here is my code: The snippet that sends the packet to the server SimpleChannelNetwork.CHANNEL.sendToServer(new CreateStructureCompass("fortress")); The file that manage the traffic package io.github.bossmania.NetherandEndMaps.core.network; import io.github.bossmania.NetherandEndMaps.NetherandEndMaps; import io.github.bossmania.NetherandEndMaps.core.network.message.CreateStructureCompass; import net.minecraft.util.ResourceLocation; import net.minecraftforge.fml.network.NetworkRegistry; import net.minecraftforge.fml.network.simple.SimpleChannel; public class SimpleChannelNetwork { public static final String NETWORK_VERSION = "0.1.0"; public static final SimpleChannel CHANNEL = NetworkRegistry.newSimpleChannel( new ResourceLocation(NetherandEndMaps.MOD_ID, "network"), () -> NETWORK_VERSION, version -> version.equals(NETWORK_VERSION), version -> version.equals(NETWORK_VERSION)); public static void init() { CHANNEL.registerMessage(0, CreateStructureCompass.class ,CreateStructureCompass::encode, CreateStructureCompass::decode, CreateStructureCompass::handle); } } the code that handle the packet receive and where I want the server to send back a packet to the client package io.github.bossmania.NetherandEndMaps.core.network.message; import java.util.function.Supplier; import io.github.bossmania.NetherandEndMaps.common.items.TemporaryItem; import net.minecraft.entity.player.ServerPlayerEntity; import net.minecraft.item.ItemStack; import net.minecraft.network.PacketBuffer; import net.minecraft.util.math.BlockPos; import net.minecraft.world.gen.feature.structure.Structure; import net.minecraft.world.server.ServerWorld; import net.minecraftforge.fml.network.NetworkEvent; import net.minecraft.item.Item; import net.minecraft.item.ItemGroup; public class CreateStructureCompass { public String structureType; public CreateStructureCompass() { } //create the constructor and store the structureType public CreateStructureCompass(String structureType) { this.structureType = structureType; } //encode the message public static void encode(CreateStructureCompass message, PacketBuffer buffer) { buffer.writeString(message.structureType); } //decode the message public static CreateStructureCompass decode(PacketBuffer buffer) { return new CreateStructureCompass(buffer.readString()); } //execute function when message is sent to server public static void handle(CreateStructureCompass message, Supplier<NetworkEvent.Context> contextSupplier) { NetworkEvent.Context context = contextSupplier.get(); context.enqueueWork(() -> { //get the player and the server ServerPlayerEntity player = context.getSender(); ServerWorld SEWorld = player.getServerWorld(); //get the location of the structure BlockPos structureLocation = SEWorld.func_241117_a_(Structure.FORTRESS, player.getPosition(),100, false); //this is where I want the server to send structureLocation back to the player }); context.setPacketHandled(true); } }

After doing some digging, I found out that ServerWorld.func_24117_a_(Structure<?>, BlockPos, int, Boolean) return the BlockPos of the structure. Thanks for your help.

I have tried using that, but it says that the method is undefined. Where can I find the locate command?

Hi, so I am currently making a custom compass that points to a structure. I was able to get the compass to point to a hard coded location, but I want it to point to a structure, like a village. I have tried looking through the web to find an answer, but no results have shown up. So, how do I get a coordinate of a structure?

So then, how else do I get a loot table to run in the code?

So how do I access the server, and send the ServerWorld to the client?

How do I check it? And if it's not an instance of ServerWorld, then how do I get the ServerWorld?

Ok, so after doing some digging into the Block class, I have found out that it uses this function to run a loot table. public static List<ItemStack> getDrops(BlockState state, ServerWorld worldIn, BlockPos pos, @Nullable TileEntity tileEntityIn, @Nullable Entity entityIn, ItemStack stack) { LootContext.Builder lootcontext$builder = (new LootContext.Builder(worldIn)).withRandom(worldIn.rand).withParameter(LootParameters.field_237457_g_, Vector3d.copyCentered(pos)).withParameter(LootParameters.TOOL, stack).withNullableParameter(LootParameters.THIS_ENTITY, entityIn).withNullableParameter(LootParameters.BLOCK_ENTITY, tileEntityIn); return state.getDrops(lootcontext$builder); } But, how do I get a ServerWorld to pass into the function? I have tried passing "(ServerWorld)World", like how the Block class did it, but it crashes the game. This is the error message. The game crashed whilst unexpected error Error: java.lang.ClassCastException: net.minecraft.client.world.ClientWorld cannot be cast to net.minecraft.world.server.ServerWorld Exit Code: -1

So I tried to look for how Blocks call the loot table, but I was not able to find it. Can you provide how it calls the loot table?

Can you elaborate more on that, and give an example of it?

I was able to get a recipe loot table to generate an explorer map, but the problem with this method is that I want the explorer maps to also point to structures in all three dimensions, and I can't prevent the player from crafting the map in the wrong dimension.

Hi, I'm new to modding and to this forum, and I'm trying to get an item that gives the player an explorer map that points to a village. I was able to do this with a loot table, but I was only able to get the loot table to run when a block is broken. Is there a way to have a loot table to run in code, or is there a different way to create an explorer map that points to a village?
