Editing various Minecraft mechanics

Hello, coders.
I'm currently being fascinated by Terra Firma Craft and I'd love to create a plugin with similar mechanics. If you know the answer, tell me how to do that:

1. Create a dummy inventory for a 5x5 crafting table Not answered
2. Remove Minecraft recipes Answered
3. Lengthen the time of fire being lit Answered

I'm sure I will have to use CraftBukkit. Thanks for your help and sorry for my bad english.

1. Build an instance of the recipe you want to remove, then remove it from the List returned by getServer().getRecipes().
2. To double the time: Listen to the BlockDecayEvent, check if it's fire, then cancel the event and add the coords and world to a List, preferably in the form of a custom class. Then, when you do listen for the BlockDecayEvent again, only cancel it if the location isn't on the List. If it is, allow the event and remove the coords from the List. You can easily use a HashMap instead to triple the time or more, by mapping the location to an integer representing the number of times the block has decayed, and deleting it once it gets to a certain point.

Neat name, haha.
Okay so, few questions: Is there a better way than saving the fire in a list? Because I have a feeling that would lag the server a little, if it has to go through all the fires until it hits the correct one.
Also, I'm wondering, is there a way to remove all vanilla recipes? I'm very new to Iterators, I tried:

Code:java

 
Iterator<Recipe> recipes = getServer().recipeIterator();
 
while(recipes.hasNext()) {
 
recipes.remove();
recipes.next(); 
}
 

But that didn't work.

There will be very little lag coming from code that's just iterating through a list. It's a simple task and will not lag your server.

PHP:

public void removeRecipies () {
        Iterator<Recipe> recipeIterator = Bukkit.recipeIterator();
 
        while(recipeIterator.hasNext())
        {
            recipeIterator.remove();
        }
    }

But there is also something like:

PHP:

Bukkit.resetRecipes();

 

Fire blocks would only be added to the list when they're scheduled to go out, so even a massive fire wouldn't result in more than 1,000 entries, which is fairly small and should have a minimal impact on the memory usage.

Okay, so, that helped. Now I'm creating a new type of Crafting Tables. It is going to use a 5x5 grid for recipes and should replace the default one. I think I'm about 50% done, but I need help with InventoryHolders. The new Crafting Table should also work similarly to Project Tables in FTB - their contents stay when closing the inventory.

Code:java

 
public void open(Player player) {
 
  Inventory inv = Bukkit.createInventory(InventoryHolder?, 45, "Crafting Table"); //This is the part I don't know what to do with
 
  showBorder(inv); //Shows unavailable slots
  update(inv); //Shows contents
 
player.openInventory(inv);
 
}
 

 

Leave the first parameter null if you're creating a virtual inventory, but set it as the block you're storing it in if applicable.

 

Do you mean like: Bukkit.createInventory(loc.getBlock(), 45, "Crafting Table");? Because that doesn't work for me. Another problem: I tried creating it with null, but in this example, the boolean is null:

Code:java

public Inventory inv;
 
public void init() {
Player player = Bukkit.getPlayer("Random online player");
inv = Bukkit.createInventory(null, 45, "Crafting Table");
player.openInventory(inv);
}
 
@EventHandler
public void invClick(InventoryClickEvent event) { //A click in the "Crafting Table" inventory...
 
if(!event.getPlayer().getName().equals("Random online player")) return;
 
boolean result = event.getInventory().equals(inv); //The result is getting set to false. No idea why.
 
}
