Double jump glitch error

Hi guys I'm making a double jump plugin my code here

HTML:

package me.Nicolas.AstroHub;
 
import org.bukkit.GameMode;
import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.event.player.PlayerMoveEvent;
import org.bukkit.event.player.PlayerToggleFlightEvent;
 
public class HubJumpAndStacker implements Listener{
    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent event) {
        Player player = event.getPlayer();
        player.setGameMode(GameMode.SURVIVAL);
 
    }
 
    @EventHandler
    public void onPlayerToggleFlight(PlayerToggleFlightEvent event) {
        Player player = event.getPlayer();
        if (player.getGameMode() != GameMode.CREATIVE) {
            player.setAllowFlight(false);
            event.setCancelled(true);
            player.setFlying(false);
            player.setVelocity(player.getLocation().getDirection().multiply(1.5).setY(1));
        }
    }
    @EventHandler
    public void onMove (PlayerMoveEvent e) {
        Player player = e.getPlayer();
        if (player.getGameMode() != GameMode.CREATIVE && player.getLocation().subtract(0,1,0).getBlock().getType() != Material.AIR && ! player.isFlying()) {
            player.setAllowFlight(true);       
        }
    }
}

It works fine and all but sometimes if you press the jump bar too fast it will glitch and allow the user to triple jump can anyone give me any ideas on how to fix this?

 

CaptainUniverse put on a cooldown

 

CaptainUniverse instead of subtracting 1, try subtracting 0.1... or 0.0001

 

JordyPwner by cooldowns you mean repeatable tasks with the bukkit scheduler right? well that might lag out big servers because this plugin is actually for a friend of mine who has hundreds of people on all the time. and fireblast709 I trried 0.1 and lower and they all didn't work got any other ideas?

 

CaptainUniverse debug why it doesn't work. That should give you an idea how to make it work.

 

I'm not actually sure why itsnot working fireblast709 thats why I'm talking in a forum :3

 

CaptainUniverse

Use a cooldown system using HashMaps?

 

Anonymous350 like I said earlier Bukkit runnables a.k.a repeatable tasks cause lag to a server
