Solved Help with args

Discussion in 'Spigot Plugin Development' started by Creatos137, Apr 25, 2017.

  1. Hey,

    I made custom items and I wanted to spawn them in with a command so I decided to use args in my command to make my command smaller.
    But my command is not working, can someone help me?

    Thank you for your time,

  2. Use equals() to compare Strings!

    Or for args I would use equalsIgnoreCase()
    • Agree Agree x 2
  3. Definitly use String#equalsIgnoreCase() if you're working on commands and other user input that requires text!
  4. 1.: At the moment you will always return false if the arguments length is 1, otherwise you will return true. Shouldn't this be the other way around?
    2.: I recommend using a switch statement instead of those if statements (when checking the value of args[0]:
    3.: Are you sure returning false if the sender is not a player a good idea? Why don't you send the CommandSender a message explaining that only players can use the command, then return true?
    4.: You set the player's first inventory slot to the desired item, are you sure you don't want to add it to an empty slot in their inventory instead?
    5.: Your class is named "Item". I don't think this is a good choice: it's very generic and it doesn't show that this class handles commands.
    I believe the other issues have already been explained.

  5. So I changed it to
    Code (Text):
    if (arg[0].equalsIgnoreCase("BeginnerSword"))
    Is this right?
    • Agree Agree x 1
  6. It doesn't give me the item :(
  7. Code (Text):
    public boolean onCommand (CommandSender sender, Command command, String label, String[] args) { //Variable name: arg -> args
        if (!(sender instanceof Player)) {
            sender.sendMessage (ChatColor.RED + "Only players can use this command!"); //Instead of returning false
            return true;
        Player player = (Player)sender;

        if (args.length == 1) {
            switch (args[0].toLowerCase ()) { //Switch statement instead of multiple if-s
                case "beginnersword":
                    player.getInventory ().setItem (0, swords.beginnerSword ()); //Instead of setting an inventory slot directly, you should put the item into an empty slot
                    return true;
                case "ironsword":
                    player.getInventory ().setItem (0, swords.ironSword ());
                    return true;
                case "longsword":
                    player.getInventory ().setItem (0, swords.longSword ());
                    return true;
        return false;

    Are you sure the "swords.beginnerSword ()" returns a valid item? Do a test where you replace it with "
    new ItemStack (Material.STONE_SWORD)".
  8. OP response? Found anything? Still need help?
