Remove Item from Dispenser Inventory

Hi,
I recently wrote a Plugin that plants blocks in front of the dispenser instead of, well dispensing them.
Until now I wanted it to be infinite, but now I want it to be usable by player and because I cancel the event to prevent the item from being dispensed I now need to remove the dispensed item from the inventory.
Until now I have this in the onDispense EventHandler

Code:java

 
ItemStack justDispensed = event.getItem();
dispenserInv = ((Dispenser) event.getBlock().getState()).getInventory()
dispenserInv.removeItem(justDispensed);
 

but this only works if the stack of the item in the dispenser is >2 when the amount is 2 it just stops decreasing.

Just set an int with the amount in the stack on dispense and after(or before) you have placed the block set the amount in the stack to 1 less than it previously was.

 

Ok, so I got this:

Code:java

 
int slot = dispenserInv.first(justDispensed);
ItemStack slotStack = dispenserInv.getItem(slot);
if(slotStack.getAmount() > 1) {
   slotStack.setAmount(slotStack.getAmount()-1);
   dispenserInv.setItem(slot, slotStack);
} else {
   dispenserInv.clear(slot);
}
 

unfortunately is slot always -1 and I'm not sure why,
does the ammount in the ItemStack need to match the one in the Inventory, and how else can I get the right slot, because I don't want to use first(Material) because searching by Material doesn't work with different types of wood etc

 

Can I see the whole of the code for that method so I can see how to fix it.

 

Code:java

 
 
Block block = event.getBlock();
 
ItemStack justDispensed = event.getItem();
 
Inventory dispenserInv = null;
if (block.getState().getType().equals(Material.DISPENSER)) {
dispenserInv = ((Dispenser) block.getState()).getInventory();
} else {
dispenserInv = ((Dropper) block.getState()).getInventory();
}
 
if (justDispensed.getType().isBlock() && !justDispensed.getType().equals(Material.TNT)
&& block.getState().getType().equals(Material.DISPENSER)) {
 
MaterialData d = block.getState().getData();
org.bukkit.material.Dispenser disp = (org.bukkit.material.Dispenser) d;
BlockFace face = disp.getFacing();
 
Location loc = block.getLocation();
 
loc.setX(loc.getX() + face.getModX());
loc.setY(loc.getY() + face.getModY());
loc.setZ(loc.getZ() + face.getModZ());
 
Block b = loc.getWorld().getBlockAt(loc);
b.setTypeIdAndData(justDispensed.getTypeId(), justDispensed.getData().getData(), false);
if (!BlockUtils.hasMatchingSign(block, BlockUtils.INFINITE)) {
int slot = dispenserInv.first(justDispensed);
ItemStack slotStack = dispenserInv.getItem(slot);
if(slotStack.getAmount() > 1) {
slotStack.setAmount(slotStack.getAmount()-1);
dispenserInv.setItem(slot, slotStack);
} else {
dispenserInv.clear(slot);
}
 
}
event.setCancelled(true);
 
} else if (BlockUtils.hasMatchingSign(block, BlockUtils.INFINITE)) {
justDispensed.setAmount(1);
dispenserInv.addItem(justDispensed);
}
 

That's the whole method, the MatchingSign is true if there is a sign with [infinite] nearby

 

event.getItem() returns an itemstack with size of 1 the item dispensed.
The slot is -1 because there is no slot it's just an item.

 

Sorry I don't really get what you mean, don't I have an Itemstack with the right Itemtype from getItem()?
Where else do I get the right type to get a slot ?
Because I need the slot of the Inventory in which the Itemstack is don't I? How else can I manipulate the Inventory

 

What event are you using?
It's weird that your first method didn't work TBH.

 

Like I wrote in the first post my method is the

Code:java

@EventHandler
public void onDispense(BlockDispenseEvent event) {

 

Wow, I really can't help you, I'm sorry.

 

Well, Thanks for trying
