Solved How do no fall damage for 20 seconds After player enter a special command

Hello I want your help for my random teleport plugin because the plugin teleport player on x:x y:256 z:x so after player was teleport he die . I want know how to render player invincible for 20 seconds

 

@OrnomaS
When you teleport them, add them to a list.
Check for Entity Damage Event and check the Entity is a player
If said player is in that list then use event#setcancelled();
Then remove the player after the allotted 20 seconds.

 

you can give the code

Joueur joueur = (joueur) expéditeur;
Emplacement ploc = player.getLocation ();
Emplacement rtp = new Emplacement (player.getWorld (), ploc.getX () + random.nextInt (5000), 256, ploc.getZ () - random.nextInt (5000), 0f, 0f);

ArrayList list = new ArrayList ();
list.add (expéditeur);

player.sendMessage ("§bTeleportation aleatoire ...");
player.teleport (rtp);
}
return false;
}

@Gestionnaire d'événements
public void onCancelFallDamage (EntityDamageEvent e)
{
nouveau BukkitRunnable ()
{

@Passer outre
run void publique ()
{
if (e.getEntity () instance de Player)
{// Vérifie si l'entité qui subit les dégâts est un joueur
if (e.getCause () == DamageCause.FALL)
{// Si la cause du dommage est un dommage de chute
e.setCancelled (true); // vous annulez l'événement.
}
}

}
} .runTaskLater (plugin, 400);
}
}

est bon ?

 

as tim said make a timer with bukkit runnable.

Code:

//bukkit runnable times etc.

make a boolean. Make an Event Handler onDamage Event if the boolean is true e.setCancelled(true);
after your bukkit time you will set the boolean to false;

 

I have find the best solution World.getHighestBlockYAt(rtp) so thats give it.

Code:

package fr.ornomas.plugin.commands;


import java.util.Random;

import org.bukkit.ChatColor;
import org.bukkit.Location;
import org.bukkit.World;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

public class CommandRtp implements CommandExecutor 
{

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String msg, String[] args) 
    {
        if (sender instanceof Player)
        {
            Player player = (Player)sender;
            World World = player.getWorld();
            Random random = new Random();
            Location ploc = player.getLocation();
            int x = (int) (ploc.getX() + random.nextInt(5000));
            int z = (int) (ploc.getZ() - random.nextInt(5000));
            Location rtp = new Location(player.getWorld(), x, 50, z, 0f, 0f);
            Location rtp1 = new Location(player.getWorld(), rtp.getX(), World.getHighestBlockYAt(rtp), rtp.getZ(), 0f, 0f);
            player.sendMessage(ChatColor.DARK_GRAY +  "Teleportation aleatoire...");
            player.teleport(rtp1);
        }
       
        else 
        {
            System.out.println(ChatColor.DARK_GRAY + "Seul les joueurs peuvent executer cette commande");
        }
        return false;
    }
   
}
