    • [15Aug2022 20:46:23.662] [Render thread/ERROR] [net.minecraft.client.Options/]: Failed to load options java.lang.NullPointerException: Cannot invoke "net.minecraft.client.KeyMapping.m_90865_()" because "keymapping" is null at net.minecraft.client.Options.processOptionsForge(Options.java:897) ~[client-1.19-20220607.102129-srg.jar%23381!/:?] at net.minecraft.client.Options.load(Options.java:973) ~[client-1.19-20220607.102129-srg.jar%23381!/:?] at net.minecraftforge.client.loading.ClientModLoader.lambda$finishModLoading$7(ClientModLoader.java:129) ~[forge-1.19-41.1.0-universal.jar%23386!/:?] This error looks very dubious. It basically says a mod has changed the Options.keyMappings and inserted a null value. If the mod used the correct way to do this, it would be impossible, there would be an error when it tries to do it. Unfortunately, the error does not say which mod causes the problem.
    • You should init the SimpleChannel instance at the end of the register method. No you need to cancel the Event and then send the Packet via the SimpleChannel to the client: // inside your LivingDeathEvent EventHandler event.setCanceled(true); if (event.getEntity() instance ServerPlayer player) { ModMessages.sendToPlayer(new TotemBellotoClientPacket(), player); } This code above is an example which is not tested.
    • The log you post does not contains any error which cause the game to crash. The file is called "debug (2).log" so it could be from a different (not the latest) run of Minecraft. If there is a file called debug.log please post it if there is no debug.log try to run the game again produced the error then. If there is still not debug.log please post launcher_log.txt as well.
    • Do you mean like the "World Type" button in the "Create New World Screen"? e.g. flat, large biomes, etc. It's not something I have looked at in recent versions. But you should look at WorldPreset which has a vanilla registry key in the Registry class you can use for DeferredRegister.   I believe you can also add them with using the datapack mechanism if you only want to resuse vanilla logic. The only thing I can find on the json format (beyond reading the codec) is this? https://misode.github.io/worldgen/world-preset/ 
    • Like this? SimpleMessage -> import net.minecraft.network.FriendlyByteBuf; import net.minecraft.resources.ResourceLocation; import net.minecraft.server.level.ServerPlayer; import net.minecraftforge.network.NetworkDirection; import net.minecraftforge.network.NetworkRegistry; import net.minecraftforge.network.PacketDistributor; import net.minecraftforge.network.simple.SimpleChannel; import java.util.function.BiConsumer; public class ModMessages { private static SimpleChannel INSTANCE; private static int packetId = 0; private static int id() { return packetId++; } public static void register() { SimpleChannel net = NetworkRegistry.ChannelBuilder .named(new ResourceLocation(Belloto.MOD_ID, "messages")) .networkProtocolVersion(() -> "1.0") .clientAcceptedVersions(s -> true) .serverAcceptedVersions(s -> true) .simpleChannel(); INSTANCE = net; net.messageBuilder(TotemBellotoPacket.class, id(), NetworkDirection.PLAY_TO_SERVER) .decoder(TotemBellotoPacket::new) .encoder(TotemBellotoPacket::toBytes) .consumer(TotemBellotoPacket::handle) .add(); net.messageBuilder(TotemBellotoClientPacket.class, id(), NetworkDirection.PLAY_TO_CLIENT) .decoder(TotemBellotoClientPacket::new) .encoder(TotemBellotoClientPacket::toBytes) .consumer(TotemBellotoClientPacket::handle) .add(); } public static <MSG> void sendToServer(MSG message) { INSTANCE.sendToServer(message); } public static <MSG> void sendToPlayer(MSG message, ServerPlayer player) { INSTANCE.send(PacketDistributor.PLAYER.with(() -> player), message); } } TotemClientPacket-> package com.naim.belloto.networking.packet; import com.naim.belloto.Init.ItemInit; import com.naim.belloto.networking.handler.ClientPacketHandlerClass; import net.minecraft.client.Minecraft; import net.minecraft.client.multiplayer.ClientLevel; import net.minecraft.network.FriendlyByteBuf; import net.minecraft.server.level.ServerLevel; import net.minecraft.server.level.ServerPlayer; import net.minecraft.sounds.SoundEvents; import net.minecraft.sounds.SoundSource; import net.minecraft.world.entity.player.Player; import net.minecraft.world.item.ItemStack; import net.minecraftforge.api.distmarker.Dist; import net.minecraftforge.fml.DistExecutor; import net.minecraftforge.network.NetworkEvent; import java.util.function.Supplier; import java.util.logging.Level; public class TotemBellotoClientPacket { public TotemBellotoClientPacket() { } public TotemBellotoClientPacket(FriendlyByteBuf buf) { } public void toBytes(FriendlyByteBuf buf) { } public boolean handle(Supplier<NetworkEvent.Context> ctx) { NetworkEvent.Context context = ctx.get(); context.enqueueWork(() -> { // Client DistExecutor.unsafeCallWhenOn(Dist.CLIENT,() -> () -> ClientPacketHandlerClass.handlePacket(ctx)); }); return true; } } And the handler like u say package com.naim.belloto.networking.handler; import com.naim.belloto.Init.ItemInit; import net.minecraft.client.Minecraft; import net.minecraft.client.multiplayer.ClientLevel; import net.minecraft.world.entity.player.Player; import net.minecraft.world.item.ItemStack; import net.minecraftforge.network.NetworkEvent; import java.util.function.Supplier; public class ClientPacketHandlerClass { public static boolean handlePacket(Supplier<NetworkEvent.Context> ctx) { Player player = Minecraft.getInstance().player; ClientLevel level = Minecraft.getInstance().level; Minecraft.getInstance().gameRenderer.displayItemActivation(new ItemStack(ItemInit.TOTEM_BELLOTO.get())); //level.playSound(null, player.getOnPos(), SoundEvents.TOTEM_USE, SoundSource.PLAYERS, 0.5F, level.random.nextFloat() *0.1F + 0.9F); return true; } } And u said to me i need to cancel LivingDeathEvent via my simpleChannel, but i need to put it in a packet? or what, im lerning about Networking im really confuse. can u give me an example or pseudocode pls
