1.8.8 Creating some kind of String#replace

Discussion in 'Spigot Plugin Development' started by Wilsoon, Feb 20, 2020.

  1. So, I have my config.yml for my plugin, and I want anything from a stringlist of commands to change {target} to target.getName() and {challenger} to challenger.getName(), however I've tried
    Code (Java):

    for(String command : SpleefGame.getInstance().getConfig().getStringList("commands")) {
                    final ConsoleCommandSender console = Bukkit.getServer().getConsoleSender();
                    command.replace("{target}", player.getName());
                    command.replace("{challenger}", challenger.getName());
                    Bukkit.dispatchCommand(console, command);
    and it doesn't seem to work, what's the right way to do it?
  2. String is immutable, so the replace method returns a new string and doesn't modify the original one. You need to use that new string to continue with.

  3. Try this:
    Code (Java):
    for (String command : SpleefGame.getInstance().getConfig().getStringList("commands")) {
        final ConsoleCommandSender console = Bukkit.getConsoleSender();
        Bukkit.dispatchCommand(console, command.replace("{target}", player.getName()).replace("{challenger}", challenger.getName()));

  4. On a related note: String#replace uses a regular expression for its first argument (see the JavaDoc for Pattern). Some characters would need to be escaped, although this does not apply in your case. Just keep it in mind for the future. ;)
    Edit: Nevermind, thought of String#replaceAll.

  5. Oh, thank you!
    Hmm, I don't seem to understand why the #replace is at Bukkit#dispatchCommand instead of being at a separate area.

    No it does not. String#replaceAll(...) Uses regex.

  7. In the example that doesn't really matter. You can first store it in a variable and then reference that variable inside the Bukkit.dispatchCommand, or you can put it directly in that method. Depending on what you prefer you can do either.
