Development Assistance Preform a command before beginning an Event

Hello, I'm having a little trouble with a plugin I'm trying to make. In this plugin, I'm trying to make it get a block ID and location when right-clicking the said block, but before you right-click the block, you must preform a command (/blockinfo). I have figured out how to do so.. but when I attempt to add the UUID to the List when they perform the command.. it doesn't. <-- LINE 33 (BlockGet.java)

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;

import org.bukkit.plugin.Plugin;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin{
    private static Plugin plugin;
 
    static ConfigManager cm = ConfigManager.getInstance();
 
    static String prefix;
 
 
 
    @Override
    public void onEnable(){
        plugin = this;
        ConfigManager.setup(this);
        registerEvents(this, new BlockGet());
        getCommand("blockinfo").setExecutor(new BlockGet());
        prefix = color(cm.getConfig().getString("prefix"));
    }
 
    @Override
    public void onDisable(){
 
    }
 
    public static void registerEvents(org.bukkit.plugin.Plugin plugin, Listener... listeners) {
        for (Listener listener : listeners) {
            Bukkit.getServer().getPluginManager().registerEvents(listener, plugin);

EDIT: I updated my codes, and addressed more details about the issue.

Any help would be appreciated, thank you.

 

What will right clicking the block do? I'm having a hard time understanding what you said.

 

@Dsi_Mario

I'll edit my post, but what I mean is that when you right-click the block (after preforming the /blockinfo command) it shows you the block information, which is the block location and the block ID.

 

You can make a HashMap of a player and a boolean to see if they did a command, and then Listen in on PlayerInteractEvent, see if the action is right clicking a block, and then give the block information (event.getClickedBlock().getX(), y, z, event.getClickedBlock().getTypeId()).

Then again, I'm bad at explaining things, and this probably isn't the best way of doing things.

 

@Dsi_Mario

Could you give me an example in code?

 

What part do you want an example for?

 

That part
@Dsi_Mario

 

Code:

public HashMap<UUID, Boolean> s = new HashMap<>();

command checks here{
UUID u = sender.getUniqueId();
if(s.containsKey(y){
if(s.get(u)){
s.put(u, false);
//Doing the command while activated
}else{
s.put(u, true);
//Doing the command while non activated
}
}else{
s.put(u, true);
//First time doing the command
}

A hashmap is unnessesery
You could save the players to a list then add them to the link on the command and on block click remove them.

 

I updated my codes, and addressed new details to the issue in the first post.

 

@Ruptur
I guess I had HashMaps on the mind.
