Solved .replace and .split problems

So I decided to make my own shop plugin and when i run it and place a admin sign i get an error on the .replace and .split methonds i used....



My Code:

Code:java

@EventHandler
  public void onInteract(PlayerInteractEvent event)
  {
    if (event.getAction() == Action.RIGHT_CLICK_BLOCK) {
      Inventory i = this.plugin.getServer().createInventory(null, InventoryType.MERCHANT);
      event.getPlayer().openInventory(i);
      if ((event.getClickedBlock().getType() == Material.WALL_SIGN) || (event.getClickedBlock().getType() == Material.SIGN)) {
        Sign sign = (Sign)event.getClickedBlock().getState();
        if (sign.getLine(1).equalsIgnoreCase(this.plugin.getConfig().getString("sell_sign"))) {
          Material currency = Material.getMaterial(this.plugin.getConfig().getString("currency"));
          String author = sign.getLine(0).replace(ChatColor.AQUA, "");
          int quantity = Integer.parseInt(sign.getLine(2).split(" " + ChatColor.GREEN)[0]);
          if (quantity <= 0) {
            event.getPlayer().sendMessage(ChatColor.RED + this.plugin.getConfig().getString("bad_quantity"));
            return;
          }
          String[] parsed = sign.getLine(2).split(ChatColor.GREEN)[1].split(":");
          if (parsed.length < 2) {
            parsed[1] = "0";
          }
          Material material = Material.getMaterial(parsed[0]);
          ItemStack sold = new ItemStack(material, quantity, (short)0, Byte.valueOf((byte)Integer.parseInt(parsed[1])));
 
          if (material == null) {
            event.getPlayer().sendMessage(ChatColor.RED + this.plugin.getConfig().getString("bad_material"));
            return;
          }
          int price = Integer.parseInt(sign.getLine(3).replace(ChatColor.BOLD, "").replace(this.plugin.getConfig().getString("price_prefix"), "").replace(this.plugin.getConfig().getString("price_unit"), "").replace(" ", ""));
          if ((price >= 1) && (event.getPlayer().getInventory().contains(currency, price))) {
            if (!author.equalsIgnoreCase(this.plugin.getConfig().getString("admin_shop_owner"))) {
              Block below = sign.getWorld().getBlockAt(sign.getX(), sign.getY() - 1, sign.getZ());
              if (below.getType() == Material.CHEST) {
                Chest chest = (Chest)below.getState();
                Inventory chestinv = chest.getBlockInventory();
                if (chestinv.contains(material, quantity)) {
                  chestinv.removeItem(new ItemStack[] { sold });
                  chestinv.addItem(new ItemStack[] { new ItemStack(currency, price) });
                }
                else {
                  event.getPlayer().sendMessage(ChatColor.RED + this.plugin.getConfig().getString("not_enough_in_chest"));
                }
              }
              else
              {
                event.getPlayer().sendMessage(ChatColor.RED + this.plugin.getConfig().getString("below_not_chest"));

            event.getPlayer().updateInventory();
 
          }
          else

Help?

 

ICostaEx
I am not sure that you understand what the replace method does. Take a look at this.
And I don't even know what you're trying to do here:
String[] parsed = sign.getLine(2).split(ChatColor.GREEN)[1].split(":");

 

Gnat008
Im getting the line of the sign and replacing it with the currency item...

and the .split is to so the same thing basically...

 

ICostaEx
What I see here:
String author = sign.getLine(0).replace(ChatColor.AQUA, "");
Is you trying to replace a ChatColor with an empty String.

And then later on you try to split a String with a ChatColor...?

 

Gnat008
String author = sign.getLine(0).replace(ChatColor.AQUA, "");

Is me trying to replace Sign line(0) with the given variable for say if its a sell sign it replaces it with the player name but with that chat color...

and if its a adminsell sign it replaces line(0) with a config string i set up, and it adds that chat color.

 

ICostaEx
You might want to try using the Sign's setLine(int index, String line) method for that.

 

Gnat008
Why is it that the .replace value works on ther parts? for example...

Code:java

event.getPlayer().sendMessage(this.plugin.getConfig().getString("sell_notice").replace("${quantity}", quantity).replace("${material}", material.name()).replace("${price}", price));

I only get the error on the first .replace

Never mind, my great friend Trixy helped me fix this.
It was an easy fix.

ICostaEx
What's the error?
Nevermind.
