opening a custom inventory getting error

Hello,

I have been coding a custom inventory plugin that i have been having issues bringing the inventory up in-ingame.... I have also debug'ed the code to find the error and its the setting of the custom inventory...

heres the code:

It should be obvious that i have a variable : private static Plugin plugin; at the top of my code

Code:

@EventHandler
    public void onPlayerInteract(PlayerInteractEvent event) {
     
        if (event.getClickedBlock() == null) return;
        Player player = event.getPlayer();
        Block block = event.getClickedBlock();
     
        if (event.getAction() == Action.RIGHT_CLICK_BLOCK) {
            if (block.getType() == Material.SIGN || block.getType() == Material.WALL_SIGN) {
                Sign sign = (Sign) block.getState();
                if (sign.getLine(0).equalsIgnoreCase(ChatColor.GREEN + "[csell]")) {
                    csell = plugin.getServer().createInventory(player, 9, "Chest Sell");
                    player.openInventory(csell);
                }
                return;
                 
            }
            return;
        }
        return;
    }

Error happens at the
csell = plugin.getServer().createInventory(player, 9, "Chest Sell");

I had added Debug messages for each if statement and i got it to successfully pass through the

if (sign.getLine(0).equalsIgnoreCase(ChatColor.GREEN + "[csell]")) {
csell = plugin.getServer().createInventory(player, 9, "Chest Sell");
player.openInventory(csell);
}
I added p.sendmessage after this if statement and it passed it but then i added a sendmessage after the csell = statement and it wouldn't pass that send message

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Use

Code:java

Bukkit.getServer().createInventory(null, 9, "Your inventory");

 

worked thank you so much es359
