[URGENT] Double Jump Not Working?

Hey im making a double jump plugin.. heres the code:

Code:java

package me.XxZHALO13Xx.DoubleJump;
 
import org.bukkit.ChatColor;
import org.bukkit.GameMode;
import org.bukkit.Material;
import org.bukkit.Sound;
import org.bukkit.block.BlockFace;
import org.bukkit.entity.Player;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerMoveEvent;
import org.bukkit.event.player.PlayerToggleFlightEvent;
import org.bukkit.plugin.java.JavaPlugin;
 
public class DoubleJump extends JavaPlugin implements Listener {
 
 
public void onEnable() {
    getServer().getPluginManager().registerEvents(this, this);
}
 
    public void onFly(PlayerToggleFlightEvent event) {
        Player player = event.getPlayer();
        if (player.getGameMode() != GameMode.CREATIVE) {
            event.setCancelled(true);
            player.setAllowFlight(false);
            player.setFlying(false);
            player.setVelocity(player.getLocation().getDirection()
                    .multiply(0.5).setY(0.5));
            player.playSound(player.getLocation(), Sound.BLAZE_BREATH, 600, 600);
            player.sendMessage(ChatColor.GOLD + "[Double Jump] " + ChatColor.AQUA + "You Double Jumped!");
        }
    }
 
 
        public void onMove (PlayerMoveEvent event){
            if ((event.getPlayer().getGameMode() != GameMode.CREATIVE) &&
                    (event.getPlayer().getLocation().getBlock()
                            .getRelative(BlockFace.DOWN).getType() != Material.AIR))
                event.getPlayer().setAllowFlight(true);
 
        }
    }
