Problem with countdowns and hashmaps?

So basically, im trying to make it so when a player stands at a location for a certain amount of time, and if they are on there for that amount of time they win. For some reason, when they are on the location, it doesn't let them win/start the countdown.. Not sure why.

Code:

package me.liam.KOTH;

import java.util.HashMap;

import me.liam.main.Kitpvp;
import me.liam.util.Hill;

        if(!(sender instanceof Player)){
            return false;
        }
        final Player player = (Player)sender;

        if (command.getName().equalsIgnoreCase("KOTH")){
            players.put(player.getName(), 1);
            numbers.put(player.getName(), +1);
        }


        if(numbers.size() == 2){

}

Also, for some reason I cannnot damage someone after the invincibilty is up.
Both problems are related because they both use the time hashmap... So im not sure whats up with that! Any help?

 

Hello? D:

 

@Treeline1

1. You can do better than just schedule a bunch of tasks one after another.
2. Don't use Async tasks for Bukkit methods you are using.

 

I think it needs more tasks.

 

Ok, thats fixed with the Async... but how do I fixed my current problem?

 

Seriously? Why so many tasks? Why you can't just do a HashMap with a <String, Float> and do a timer? It's better and more organized!

 

@Treeline1
where's do you assign 'a' ? before to put it in the hashmap ?

I might miss it. Get a look to repeating task. it will help you a lot.

Another way, use the system.currentmillis and the event entityDamageByEntity.
