Removing certain amount of items from inventory, including renamed items, damaged items etc.

I am having a bit of trouble here, I am making a method which removes certain amount of items of one type, for an example emerald, from the inventory, but when I call the "inv.removeItem(stack, amount)" method, it won't remove renamed items, damaged items etc.

Then I tried another method which was this:

Code:java

 
int toRemove = amount;
 
for(int i = 0; i < toRemove; i++) {
inv.remove(inv.first(getCurrentItem())); // material, not itemstack
 }
 

But that didn't do anything.

Then I tried this, which was a total failure. (Probably just me derping)

Code:java

 
int toRemove = amount;
 
for(int i = 0; i < toRemove; i++) {
for(ItemStack is : inv.getContents()) {
if(is != null) {
if(is.getType() == getCurrentItem()) {
inv.remove(is); // I need to call the inv.remove method, but I don't know how I would I would just remove 1 item of the itemstack instead of the whole itemstack.
break;
}
}
}
}
 

I am always updating the inventory of the player after calling these methods.

This is from one of my plugins;

Code:java

 
ItemMeta meta = null;
 
if (player.getItemInHand().hasItemMeta())
    meta = player.getItemInHand().getItemMeta();
 
ItemStack remove = new ItemStack(itemid, amountadding);
 
 
if (subitemid != 0) {
    remove.setDurability((short) subitemid);
}
 
if (player.getItemInHand().hasItemMeta()) {
    remove.setItemMeta(meta);
}
 
player.getInventory().removeItem(remove);
player.updateInventory();
 

Could do with some better editing, but it's laid-out like that because there are things going on between those lines.

Why didn't I think of that.. I'll try it, thanks!
