Solved If player has item with X amount?

Ok so I am just trying simple things for my plugin.
What i want:
A boolean called "hasIngots" and then so i can use it like
if (hasIngots(10)) {
then do something;
}


But I want the "hasIngots" boolean to have one argument which will be how much iron ingots it needs to return true. else return false.

Thank you!

 

If you just want to make sure that the player has a certain amount of ingots, you can create the boolean method eg. like this:

PHP:

public static boolean hasIngots(int amount) {
    if(amount == 10)
        return true;
    return false;
}

or if you want to make the code really "smooth"

PHP:

public static boolean hasIngots(int amount){
    return amount == 10;
}

Does this answer your question?

 

You can try this, but you'll also need to have an argument for the player.

Code:

public static boolean hasIngots(Player p, int minAmount) {
    return hasItem(p, Material.IRON_INGOT, minAmount);
}
 
public static boolean hasItem(Player p, Material material, int minAmount) {
    return hasItem(p, material, minAmount, (byte) 0);
}
 
public static boolean hasItem(Player p, Material material, int minAmount, byte data) {
    int totalAmount = 0;
    for (ItemStack i : p.getInventory().getContents()) {
        totalAmount += (i.getData().getData() == data && i.getType() == material) ? i.getAmount() : 0;
    }
    return totalAmount >= minAmount; //Change >= to == if you want exact amount instead
}

 

Code:

public boolean hasIngots(int amount, Material mat,  Player player){
    return player.getInventory().containsAtLeast(amount, mat);
}

 

How do I make an ItemStack?
Because I'm getting an error on the red:
if (p.getInventory().containsAtLeast(Material.IRON_INGOT, 20)) {
SOMETHING;
}

How do I fix this?

FIXED! Thanks!
