Crashing Upon Registering Command?

NolValue · October 4, 2018

So, I have finally managed to get Capabilities working for me after several months of trying to figure out what was wrong with my code, haha.

Now, since I haven't got around to setting up a GUI for showing my capabilities data yet, I decided to just use a command for easier testing purposes.

The log for the crash is here:

    public static Logger logger = LogManager.getLogger(References.MOD_ID);
    @Instance
    public static dbs instance;

    @SidedProxy(clientSide = References.CLIENT_PROXY, serverSide = References.COMMON_PROXY)
    public static CommonProxy proxy;

    @EventHandler
    public static void PreInit(FMLPreInitializationEvent event){
        ModCapabilities.registerCapabilities();
    }

    @EventHandler
    public static void Init(FMLInitializationEvent event){
    }

    @EventHandler
    public static void PostInit(FMLPostInitializationEvent event){

    }

    @EventHandler
    public void ServerStarting(FMLServerStartingEvent event) {
        event.registerServerCommand(new CommandGetStats());
    }


}

And finally, the command itself:

package NolValue.DBS.Commands;

import net.minecraft.command.CommandException;

import net.minecraft.util.math.BlockPos;
import net.minecraft.util.text.TextFormatting;

import javax.annotation.Nullable;
import java.util.List;

public class CommandGetStats implements ICommand {


    @Override
    public String getName () {
        return "CommandGetStats";
    }

    public int getRequiredPermissionLevel () {
        return 0;
    }

    @Override
    public String getUsage (ICommandSender sender) {
        return "/CommandGetStats <value>";
    }

    @Override
    public List<String> getAliases () {
        return null;
    }

    @Override
    public boolean isUsernameIndex (String[] args, int index) {
        return false;
    }

    @Override
    public void execute(MinecraftServer server, ICommandSender sender, String[] args) throws CommandException {
        if (sender.getCommandSenderEntity() instanceof EntityPlayer) if (args.length == 0){
            StatsCapability.IPlayerStats STATS = ((EntityPlayer) sender.getCommandSenderEntity()).getCapability(ModCapabilities.PLAYER_STATS, null);
            TextHelper.sendFormattedChatMessage("Strength:" + STATS.getStr() + " Defense:" + STATS.getDef() + " HitPoints:" + STATS.getHP(), TextFormatting.GREEN, (EntityPlayer) sender.getCommandSenderEntity());
        }
    }

    @Override
    public boolean checkPermission(MinecraftServer server, ICommandSender sender) {
        return false;
    }

    @Override
    public List<String> getTabCompletions(MinecraftServer server, ICommandSender sender, String[] args, @Nullable BlockPos targetPos) {
        return null;
    }

    @Override
    public int compareTo(ICommand o) {
        return 0;
    }
}

I'm not sure what would be causing the issue.

If you need any information beyond this, tell me and I'll supply it. I can't see what's causing this to error out though.

You probably cant return null in some of those methods in your command class. Also you should be using CommandBase not ICommand.

Yeah apparently it was as simple as switching to CommandBase and removing the lines that use null or 0. Thanks mate.
