How to cancel a specific recipe?

Hello,

I am using the plugin CrackShot for my server and am using diamond and gold tools as the guns.
I want to use crackshot's recipe system, but stop the players from crafting diamond and gold tools using the typical recipe system.

I managed to cancel the recipe, but it canceled the crackshot recipe as well.

What I am trying to do now is to get the recipe, get the item type and then if the name of the item contains "AK-47" then it proceeds with the crafting. If it doesn't, it cancels the recipe.

This is my code:

Code:

    
    @EventHandler
    public void craftItem(PrepareItemCraftEvent e) {
       
        Material itemType = e.getRecipe().getResult().getType();
        ItemMeta meta = e.getRecipe().getResult().getItemMeta();
       
        if (itemType == Material.GOLD_AXE) {
            if (meta.getDisplayName().contains("AK-47")) {
               
            }
            else {
               
                e.getInventory().setResult(new ItemStack(Material.AIR));
               
                for (HumanEntity he:e.getViewers()) {
                   
                    if (he instanceof Player) {
                        ((Player)he).sendMessage(ChatColor.RED + "This recipe is disabled!");
                    }
                }
            }
        }
    }

Any help would be greatly appreciated.
Thanks!

What you currently have is a "Hack". You need to remove the recipe from the server. Read this:
https://bukkit.org/threads/how-to-remove-recipes.122712/

 

Removing a certain item's recipe, and making the players not able to use these items is probably the worst thing you can do. Use an item with a lore instead.

 

What do you mean by using an item with a lore, exactly?

Players need to be able to craft the guns, but they can't be able to craft their counterpart items (ex: diamond pickaxe) with the normal vanilla recipe. It seems a bit extreme, and it is, but there is no need for players to have access to these tools on my server in the first place.
