Solved Arguments and delay between sendmessage.

Hello.
I have two problems, first one: different action if the argument is set, and if it is not set, how to do this?

Code:

    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        Player player = (Player)sender;
        if(cmd.getName().equalsIgnoreCase("chat")) {
            if (args.length == 0) {
                if(sender.hasPermission("addons.chat.help")) {
                    player.sendMessage(ChatColor.RED + "Usage: /chat [off/on/clear] [reason]");
                } else {
                    player.sendMessage(ChatColor.RED + "You don't have permission to this command!");
                }
                return false;
            }
            if(args[0].equalsIgnoreCase("clear") || args[0].equalsIgnoreCase("c")) {
                if(sender.hasPermission("addons.chat.clear")) {
                    if (args.length > 0) {                   // When arg 1 is set
                        for(int i=0; i < 100; i ++) {
                            Bukkit.broadcastMessage(" ");
                        }
                        Bukkit.broadcastMessage(ChatColor.RED + "The chat has been cleared, reason:" + args[1] + "!");
                    } else {                    // When arg 1 is not set
                        for(int i=0; i < 100; i ++) {
                            Bukkit.broadcastMessage(" ");
                        }
                        Bukkit.broadcastMessage(ChatColor.RED + "The chat has been cleared!");
                    }
                } else {
                    player.sendMessage(ChatColor.RED + "You don't have permission to this command!");
                }
            }
        }
        return false;
    }
}

Second: How to make delay between sendmessage? I mean something like this:

Code:

player.sendMessage(ChatColor.RED + " message 1");
// 5 second delay
player.sendMessage(ChatColor.RED + " message 2");
// 1 second delay
player.sendMessage(ChatColor.RED + " message 3");
// 1 second delay
// rest of the code

Sorry for any mistakes, English is not my native language.

 

@MrAndeos
First problem: You're getting an "ArrayIndexOutOfBoundsException" from this line

Code:

Bukkit.broadcastMessage(ChatColor.RED + "The chat has been cleared, reason:" + args[1] + "!");

You checked args.length > 0, when you should do args.length > 1.

Second problem: You should use BukkitRunnables.

 

OK, thanks, I get both things working. I have one more question: I created new ShapedRecipe in class B, and now I need to register this recipe in Main class, how to do this?

 

@MrAndeos
Get an instance of the main class through the class B's constructor, and do Plugin#getServer().addRecipe(recipe)
