Public Variable

Hello im trying to make a punishment GUI plugin and I dont know how to make a Variable global like for instance
I want to do:

Code:java

 switch (event.getCurrentItem().getType()) {
case REDSTONE_BLOCK:
player.chat("/tempban " + args[0]); // im getting a error by args
player.closeInventory();

And here is my targeting player thingy

Code:java

 public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
Player player = (Player) sender;
Player target = Bukkit.getServer().getPlayer(args[0]);
if(commandLabel.equalsIgnoreCase("punish")) {
if (args.length == 0) {
player.sendMessage(ChatColor.RED + "Please specify player!");
return true;
 
}
 
if (target == null) {
player.sendMessage(ChatColor.RED + "Could Not Find Player " + args[0] + "!");
return true;
 
}
openGUI(player);
}
 
return false;

Just incase the entire code:

Code:java

package me.David.PrickledPvP;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.Location;

return true;
 
}
 
if (target == null) {

return true;
 
}
openGUI(player);
}
 
return false;
}
private void openGUI(Player player) {

+ "Ban Selector");
 
 
ItemStack tempban = new ItemStack(Material.REDSTONE_BLOCK);

survival.setItemMeta(survivalMeta);
 
spleefMeta.setDisplayName(ChatColor.BLUE + "Spleef");
spleef.setItemMeta(spleefMeta);
 
inv.setItem(0, tempban);
inv.setItem(1, creative);
inv.setItem(2, survival);
inv.setItem(3, spleef);
 
player.openInventory(inv);
 
}
 
@EventHandler
public void onInventoryClick(InventoryClickEvent event) {
if (!ChatColor.stripColor(event.getInventory().getName())
.equalsIgnoreCase("Ban Selector"))
return;
Player player = (Player) event.getWhoClicked();
System.out.println("Event Triggered!");
event.setCancelled(true);
 
if(event.getCurrentItem()==null || event.getCurrentItem().getType()==Material.AIR||!event.getCurrentItem().hasItemMeta()){
player.closeInventory();
return;
}
switch (event.getCurrentItem().getType()) {
case REDSTONE_BLOCK:
player.chat("/tempban " + args[0]);
player.closeInventory();
}
switch (event.getCurrentItem().getType()) {
case GOLD_BLOCK:
Location plots = new Location(Bukkit.getWorld("plots"), -163, 65, 375, -90, 0);
player.teleport(plots);
player.closeInventory();
 
}
switch (event.getCurrentItem().getType()) {
case LOG:
Location survival = new Location(Bukkit.getWorld("survival"), 25, 67, -76, 180, 0);
player.teleport(survival);
player.closeInventory();
}
switch (event.getCurrentItem().getType()) {
 
case DIAMOND_SPADE:
Location spleef = new Location(Bukkit.getWorld("spawn"), 1757, 4, -887, 90, 0);
player.chat("/warp mine");
player.closeInventory(); }
 
}
}
 
 
 
 
 
 
 
 
 

please note This is not my Main class.

 

david123718 Stack-trace?

 

Its not a error just I wanted to know a way I could do it.

 

Outside of a method.

Code:java

It appears you don't fully understand how Java works.

The onCommand method represents the code that will run when a command is executed. You need all of the code to be in there, or if you are making method calls outside of it, to pass the necessary variables there.

You are getting an error with args[] because it doesn't exist in that context. I should not you most certainly do NOT want to create a global variable. What if two people open a GUI at once?

Seeing as you have opened a GUI that pertains to a specific player, you want to save that player for when the appropriate item is selected in the GUI. The simplest way for you to do this would be to save a Map<UUID, String> for the player's name, or optimally get the player first and get their UUID, then use a Map<UUID, UUID>. When the GUI item is selected, retrieve the name/UUID of the player in question from the Map, then remove it from the map to save memory.

Really?

 

Im new can you make it a little simpler?

Can I just have a example?
