Hello, sorry for my bad english because im french.
I have a problem, when I click on the Magma_cream it's doesent worked.
This is the code:

Code:

package Plugins.Minecraft.PluginsManageur;

import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.Action;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.inventory.ItemStack;

public class ShowPlayers implements Listener {

    @SuppressWarnings("deprecation")
    @EventHandler
    public void onClick(PlayerInteractEvent e) {
        if(e.getAction() == Action.LEFT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_AIR || e.getAction() == Action.LEFT_CLICK_BLOCK || e.getAction() == Action.RIGHT_CLICK_BLOCK){
            if(e.getMaterial() == Material.MAGMA_CREAM){
                Player p = e.getPlayer();
                p.getInventory().setItemInHand(new ItemStack(Material.SLIME_BALL, 1));
                p.updateInventory();
            }else if(e.getMaterial() == Material.SLIME_BALL){
                Player p = e.getPlayer();
                p.getInventory().setItemInHand(new ItemStack(Material.MAGMA_CREAM, 1));
                p.updateInventory();
            }
        }
    }
}

thanks a lot, bye

Change your event to;

Code:

@EventHandler
    public void onInventoryClick(InventoryClickEvent event) {

That'll help a bit

 

Thank you but some errors at

Code:

if(e.getAction() == Action.LEFT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_AIR || e.getAction() == Action.LEFT_CLICK_BLOCK || e.getAction() == Action.RIGHT_CLICK_BLOCK){
            if(e.getMaterial() == Material.MAGMA_CREAM){

 

I'm having the same problem but InventoryClickEvent doesn't work. Cuz you're not clicking it after opening your inventory.

 

@RyFax
Wait a second, are you trying to catch when the player interacts with the Item (right clicking or left clicking) when he holds it? I'm sorry if I told you to do the wrong thing here >.<

Also, could you post the errors?
