Hey guys, I have made two classes I want to use to execute a commands. One of the classes (NickScan) is my command class and the other (NickScanRunnable) is my runnable class. I have a HTTP GET request running in my runnable class which is ran in my command class on 'processCommand()'. In my runnable class I edit a public variable to the String I want and then I use the Thread.join() method to connect to the thread and after retrieve my public variable which I then output. The problem is Thread.join() suspends my UI thread too. I was wondering if there was any other way to do this? I will attach code below.

 

NickScan class:

package com.mine215.nickscanner;

import net.minecraft.client.Minecraft;
import net.minecraft.command.CommandBase;
import net.minecraft.command.CommandException;
import net.minecraft.command.ICommandSender;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.util.ChatComponentText;

public class NickScan extends CommandBase {
    @Override
    public String getCommandName() {
        return "nickscan";
    }

    @Override
    public String getCommandUsage(ICommandSender sender) {
        return "command.searchnickscan.usage";
    }

    @Override
    public void processCommand(ICommandSender sender, String[] args) throws CommandException {
        EntityPlayer player = (EntityPlayer) Minecraft.getMinecraft().thePlayer;
        NickScanRunnable nsRunnable = new NickScanRunnable();
        Thread apiConnectThread = new Thread(nsRunnable);
        apiConnectThread.start();
        try {
            apiConnectThread.join();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        player.addChatMessage(new ChatComponentText(nsRunnable.resultToChat));
    }

    @Override
    public int getRequiredPermissionLevel() {
        return 0;
    }

    @Override
    public boolean isUsernameIndex(String[] args, int index)
    {
        return index == 0;
    }
}

Make it look cleaner

It's only normal for the main thread to block. I mean you join the main thread, it will be blocked until the other thread finish.
