Nxty

Ok my problem was that i was returning "null" on the "getCommandAliases" thing and the registry needs that to work. Sry i need to think about it before posting :\

Still getting the same error The error is occuring where i register the command class.

I have my main class, and it registers the adCommand class, package nxty.test; import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; import org.apache.logging.log4j.LogManager; import org.apache.logging.log4j.Logger; import net.minecraft.client.Minecraft; import net.minecraft.util.ChatComponentText; import net.minecraftforge.client.ClientCommandHandler; import net.minecraftforge.common.MinecraftForge; import net.minecraftforge.fml.common.Mod; import net.minecraftforge.fml.common.Mod.EventHandler; import net.minecraftforge.fml.common.event.FMLInitializationEvent; import nxty.util.AutoDenyThreadFactory; @Mod(modid = "autoDeny", version = "1.0", clientSideOnly = true, acceptedMinecraftVersions = "1.8.9") public class Main { public static final Logger logger = LogManager.getLogger("autoDeny"); public static Minecraft mc = Minecraft.getMinecraft(); public static final ExecutorService Threadpool; static { Threadpool = Executors.newCachedThreadPool(new AutoDenyThreadFactory()); } @Mod.Instance private static Main instance; @EventHandler public void init(FMLInitializationEvent event) { ClientCommandHandler.instance.registerCommand(new adCommand()); MinecraftForge.EVENT_BUS.register(new sendMessage()); } public static Main getInstance() { return instance; } public void sendMessage(String message, Object... replacements) { if(mc.thePlayer == null)return; try { message = String.format(message, replacements); } catch(Exception ex) { mc.thePlayer.addChatComponentMessage(new ChatComponentText(message)); } } } and i have my adCommand class: package nxty.test; import java.util.List; import net.minecraft.command.CommandException; import net.minecraft.command.ICommand; import net.minecraft.command.ICommandSender; import net.minecraft.util.BlockPos; public class adCommand implements ICommand{ public static boolean toggle = true; @Override public int compareTo(ICommand arg0) { // TODO Auto-generated method stub return 0; } @Override public String getCommandName() { // TODO Auto-generated method stub return "autodeny"; } @Override public String getCommandUsage(ICommandSender sender) { // TODO Auto-generated method stub return "Usage: /" + getCommandName() + " [on/off]"; } @Override public List<String> getCommandAliases() { // TODO Auto-generated method stub return null; } @Override public void processCommand(ICommandSender sender, String[] args) throws CommandException { // TODO Auto-generated method stub if(args[0].equals("on")) { toggle = true; Main.getInstance().sendMessage("AutoDeny is now toggled on."); } else if(args[0].equals("off")) { toggle = false; Main.getInstance().sendMessage("AutoDeny is now toggled off."); } } @Override public boolean canCommandSenderUseCommand(ICommandSender sender) { // TODO Auto-generated method stub return true; } @Override public List<String> addTabCompletionOptions(ICommandSender sender, String[] args, BlockPos pos) { // TODO Auto-generated method stub return null; } @Override public boolean isUsernameIndex(String[] args, int index) { // TODO Auto-generated method stub return false; } } and when the game loads when i try to run it, i get this crash report ---- Minecraft Crash Report ---- // You're mean.
