    Hey, I was trying to send a player a message when he/she would use a command. But, it didn't work.. :S

    I do believe this is how one sends a command to a player:
    Code:
    public boolean onCommand(CommandSender sender, Command cmd, String Label, String[] args) {
    Player player = (Player) sender;
    if(cmd.getName().equalsIgnoreCase("example")) {
    player.sendMessage(ChatColor.LIGHT_PURPLE + "This is the example message when using the example command!");
    
    }
    But, it doesn't seem to work. Please help!

    Well... What doesn't work? Error? Or just no message.
    The code looks good if your using the /example command.

    Are you trying to send a message to the sender of a command? If so use
    Code:
    sender.sendMessage() 
    
    So it would look like this:
    Code:
    [SIZE=13px][FONT=Consolas]public boolean onCommand(CommandSender sender, Command cmd, String Label, String[] args) {[/FONT][/SIZE]
    [SIZE=13px][FONT=Consolas][/FONT][/SIZE][SIZE=13px][FONT=Consolas]if(cmd.getName().equalsIgnoreCase("example")) {[/FONT][/SIZE]
    [SIZE=13px][FONT=Consolas][/FONT][/SIZE][SIZE=13px][FONT=Consolas]sender.sendMessage(ChatColor.LIGHT_PURPLE + "This is the example message when using the example command!");[/FONT][/SIZE]
    [SIZE=13px][FONT=Consolas]}[/FONT][/SIZE]

    Does your onCommand even fire?

    Put this in onCommand:
    Code:
    Logger.getLogger("Minecraft").info("onCommand fired!");
    
    Now you should get an console message with "onCommand fired!"

    Yes, I am trying to send it to the sender, I change the code to use "sender.sendMessage(ChatColor.LIGHT_PURPLE + "This is the example message when using the example command!");" but it still won't work.

    So I changed the code to be:
    Code:
    if(cmd.getName().equalsIgnoreCase("example")) {[/FONT][/SIZE][/FONT][/SIZE]
    [SIZE=4][FONT=arial][SIZE=4][FONT=arial]log.info("Command example used!");[/FONT][/SIZE][/FONT][/SIZE]
    [SIZE=4][FONT=arial][SIZE=4][FONT=arial]sender.sendMessage(ChatColor.LIGHT_PURPLE + "This is the example message when using the example command!");[/FONT][/SIZE][/FONT][/SIZE]
    [SIZE=4][FONT=arial][SIZE=4][FONT=arial]return true;[/FONT][/SIZE][/FONT][/SIZE]
    [SIZE=4][FONT=arial][SIZE=4][FONT=arial]}
    [/FONT][/SIZE]

    But, "Command example used!" doesn't appear on the console..[/CODE][/CODE][/CODE][/FONT][/SIZE][/CODE][/FONT][/SIZE]

    Sorry about the messed up thing.. :S[/CODE][/FONT][/SIZE]

    Also, when I enter in "Logger log = Logger.getLogger("Minecraft").info("onCommand fired!");", Eclipse gives me an error.

    Code:
    Type Mismatch: Cannot convert from void to logger.
    Any advice?

    Have you registered the command in your main class, and in your plugin.yml?

    use Label instead of cmd at line 4, and don't use .getName() after it, just .equalsIgnoreCase()

    Here's what I use for one of my plugins... you may edit it to your liking.
    Code:

    Code:
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){
    
            Player player = (Player) sender;
    
            if(commandLabel.equalsIgnoreCase("shelter")){
                toggleVision(player);
            }
    
            return true;
    
        }

    Try this
    Code:
    public boolean onCommand(CommandSender sender, Command cmd, String Label, String[] args) {
      Logger.getLogger("Minecraft").info("onCommand fired!");
      Player player = (Player) sender; if(cmd.getName().equalsIgnoreCase("example")) {
        player.sendMessage(ChatColor.LIGHT_PURPLE + "This is the example message when using the example command!");
      }
    PS: Don't forget to import logger
    Code:
    import java.util.logging.Logger;
    PS2: The addition of the Logger just adds some debugging. If it does print out that line in the console then you know onCommand has been fired. If not, then that's the problem!

    I tried this but when I run the command in-game, it continues responding with "Unknown command"

    Try something like this if it's in your main class

    Code:java
    1.  
    2. this.getCommand("example").setExecutor(new CommandExecutor() {
    3.  
    4. public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
    5. if (cmd.getName().toLowerCase().equals("example")) {
    6. sender.sendMessage(ChatColor.LIGHT_PURPLE + "This is the example message when using the example command!");
    7. return true;
    8. }
    9. return false;
    10. }
    11. });


    This can go in your onEnable()

    And don't forget to put it in your plugin.yml aswell.

    Code:
    name: Example
    main: <package name>.<Main class name>
    version: 0.1
    commands:
      example:
          description: derp
          usage: /<command>

    Ok, so here it is:
    Code:
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args {
    Player player = (Player) sender;
    if(commandLabel.equalsIgnoreCase("example")) {
    Logger.getLogger("Minecraft").info("onCommand fired!");
    sender.sendMessage(ChatColor.LIGHT_PURPLE + "[SIZE=13px][FONT=Consolas]This is the example message when using the example command![/FONT][/SIZE]");
    return true;
    }
    When I type "/example" in-game, it tells me Unknown Command. Also, nothing appears on the console.

    @theguynextdoor You were right. My plugin.yml layout for the command was wrong. Thank you, guys!
