    You could probably remove that line as plugin classes by default receives commands before command listeners.

    Huh... the more you know. Thanks.
     
  6. Also you don't have to implement CommandExecutor as the JavaPlugin class (indirectly) implements it. And you don't have to cast the CommandSender to a Player to check for permissions, simply use sender.hasPermission... ;)

    So considering this with the singular command registered in the plugin.yml there is no need to actually check the command label as well... Hmm Interesting. However I was always under the assumption that the console as the sender would return false on the permissions check and the registering of the command was bound to the executor defined by the plugin.
     
  8. true.
    Not if you didn't do something weird. IIRC the ConsoleCommandSender has all permissions per default. Also you have the if(sender instanceof Player) check, so why even care about the console here? ;)
    This is the case, but if you don't specify a executor it defaults to your plugins main class (JavaPlugin). That's why JavaPlugin extends PluginBase which implements Plugin which extends CommandExecutor. ;)

    Icyene

    GoldFish: 49 lines. Fishing can make you rich!

    I <marginally> cheated a bit on this plugin. It gives the player a chance to obtain loot while fishing. Color code support for catch messages.

    Code:
    package com.github.Icyene.GoldFish;
     
    import java.io.File;
    import java.util.Random;
    import org.bukkit.*;
    import org.bukkit.entity.Player;
    import org.bukkit.event.EventHandler;
    import org.bukkit.event.player.PlayerFishEvent;
    import org.bukkit.event.player.PlayerFishEvent.State;
    import org.bukkit.inventory.*;
     
    public class GoldFish extends org.bukkit.plugin.java.JavaPlugin implements
    org.bukkit.event.Listener {
    private String[] keyArray;
    private final Random rand = new Random();
    private int chance = 50;
    private static String catchMessage, withoutBaitMessage;
    public GoldFish() {}
    public void onEnable() {
    final File configFile = new File(this.getDataFolder(), "config.yml");
    if (!configFile.exists()) {
    getConfig().options().copyDefaults(true);
    saveConfig();}
    this.getServer().getPluginManager().registerEvents(this, this);
    chance = getConfig().getInt("luring.lootChance");
    catchMessage = parseColors(getConfig().getString("luring.catchMessage"));
    withoutBaitMessage = parseColors(getConfig().getString("luring.withoutBaitMessage"));
    keyArray = getConfig().getConfigurationSection("luring.loot").getKeys(
    false).toArray(new String[0]);}
    public static String parseColors(String msg) {return msg.replaceAll("&", "§");}
    @EventHandler
    public void onPlayerFishEvent(final PlayerFishEvent event) {
    if (event.getState().equals(State.CAUGHT_FISH)) {
    if (rand.nextInt(100) <= chance) {
    reward(event.getPlayer(), getConfig().getIntegerList("luring.loot."+ keyArray[rand.nextInt(keyArray.length)]).toArray(new Integer[0]));
    }}}
    public static void reward(final Player player, final Integer[] loot) {
    final PlayerInventory inventory = player.getInventory();
    final ItemStack bait = new ItemStack(Material.getMaterial(loot[2]),loot[3]);
    final ItemStack lootStack = new ItemStack(Material.getMaterial(loot[0]),loot[1]);
    for (ItemStack stack : inventory.getContents()) {
    try {if (stack.getType().equals(bait.getType())&&stack.getAmount() >= bait.getAmount()) {
    inventory.addItem(lootStack);
    player.sendMessage(catchMessage);
    inventory.removeItem(bait);
    player.updateInventory();
    return;}
    } catch (Exception e) {}}
    player.sendMessage(withoutBaitMessage);}}
    
    Obviously that does not include the configuration file :D. You'll need a config file like this to run it:

    Code:
    luring:
      loot:
        rawFish:
        - 349 #extra loot that is possible to get from fishing, in this case its Raw Fish (itemID 349)
        - 10 #how many of that extra loot you are going to get, in here its 10 Raw Fishes
        - 331 #what bait you need to have in order to get that extra loot, in this case its Redstone Dust (itemID 331)
        - 20 #how many of bait is required to get extra loot
        rawFishx20:
        - 349
        - 20
        - 331
        - 50
        compass:
        - 345
        - 1
        - 331
        - 20
      lootChance: 100
      catchMessage: '&e Your hook caught some loot' #It supports standard Minecraft colour coding
      withoutBaitMessage: '&e Oi\! You are fishing without a bait\! Consider it to get extra catch\!' #Make sure to escape (\) special characters!
    
    The above code isn't efficient at all, as I had to compact 150 lines into 50 lines, but it should work.

    P.S. I couldn't get syntax=Java to work, so for your eyes I also put it on pastie. http://pastie.org/4372444

    It's more efficient to make the player variable and use it throughout the rest of your code since you use it so many times. Also, learn to indent!

    You mean an instance variable of player? Are you sure? You'd still need to cast it each time.

    Yes, I know how to indent. I didn't pay attention to the indentation when I pasted. Stupid text formatting.

    ACStache

    the casting here is fine, if he used the player object more than 1 time through each command, it might be worth it, but since each use of (Player)sender is in an "else if" (except the first one :D) statement, it will only ever use it once per command
     
    Fishrock123 likes this.
  23. Really? He uses it exactly one time each call as he returns right after using it.

    But Fishrock123 as you return in the ifs the elses are not needed (and just waste CPU time: If it doesn't return it will always enter the else, so there's no way that the else can't be entered, so it's a useless check).

    Fishrock123 MursheX You should also check if the sender is a player before casting (else your code will crash if you execute the command from the console). Last but not least use label instead of cmd.getName() as the second one returns the first, so why get what we still have?

    You are not required to implement @Override public void onDisable() {} //or onEnable

    Just FYI. That'll save you another line. :)

    Not really sure why you're posting something here in a coding challenge if you're unsure of what it does, or how to do things. Seems like a better idea to post questions in Plugin development. You also have 55 lines of code, this is the 50 line challenge. By simply compacting your code a bit, I got it down to 49 lines. It can probably even be compacted further, but I'm not sure it currently works. Your sushi command seems off, you've got an if statement where it shouldn't, and checking if they didn't enter an argument doesn't really show whether or not they're a player.

    Code:
    package me.jacklin213.sushi;
     
    import java.util.logging.Logger;
    import org.bukkit.ChatColor;
    import org.bukkit.Material;
    import org.bukkit.command.Command;

    import org.bukkit.entity.Player;
    import org.bukkit.event.Listener;
    import org.bukkit.inventory.ItemStack;
    import org.bukkit.permissions.Permission;
    import org.bukkit.plugin.PluginDescriptionFile;
    import org.bukkit.plugin.java.JavaPlugin;
     
    public class Sushi extends JavaPlugin implements Listener {
        // define stuff
        PluginDescriptionFile pdfFile;
        public static Sushi plugin;
        public final Logger log = Logger.getLogger("Minecraft");
        public static Permission Permissions = null;
        // what to do onDisable()
        public void onDisable() {
            this.pdfFile = getDescription();
            this.log.info(this.pdfFile.getName() + " is now disabled.");
        }
        public boolean onCommand(CommandSender sender, Command cmd, String label,
                String[] args) {
            if (cmd.getName().equalsIgnoreCase("sushi") && sender.hasPermission("sushi.use") && args.length == 1) {
                Player player = (Player) sender;
                player.getInventory().addItem(new ItemStack(Material.RAW_FISH, 64));
                sender.sendMessage(ChatColor.YELLOW + "You have been givin Fish!");
                if (cmd.getName().equalsIgnoreCase("sushi") && args.length == 0) {
                    this.log.warning(ChatColor.RED + "Sorry you are not a player");
                }
            } else {
                sender.sendMessage(ChatColor.RED + "You DO NOT have the permission to do this !");
