[HELP] When a dispenser dispenses fireworks, set that stack amount to 64?

How can I, when I dispenser shoots a firework, set the stack that it took the firework from back to 64?

 

• listen to the BlockDispenseEvent
• get the block
• get the state and check if it is an instanceof Dispenser
• cast the state to Dispenser
• get the Inventory
• do whatever to it (in your case, get the stack and set the amount to 64)
• invoke .update() in the state (you casted it somewhere, invoke .update() with that instance)

 

Use this in your listener class:

Code:java

 
@EventHandler
public void onBlockDispense(BlockDispenseEvent evt){
ItemStack item = evt.getItem();
if(item.getId()==401){
Block block = evt.getBlock();
if(block.getState() instanceof Dispenser){
Dispenser dis = (Dispenser) block.getState();
dis.getInventory().addItem(new ItemStack[]{item});
dis.update();
}
}
}
 

That should work, but It might not as I haven't tested it yet and wrote it in notepad :/

Oh yeah, forgot to invoke .update()...

EDIT: Fixed it in the original post

Doesn't seem to work but I don't have any errors, it's like the DispenseEvent isn't even being called.

EDIT: I was using an older Craftbukkit, updating now should fix the issue I was having, thanks.

 

one trick you can do.. which I use for unlimited potions it to set the itemstack amount to -1. it won't use the item but still dispense it.

Code:

Dispenser disp = (Dispenser) block.getState();
Inventory inv = disp.getInventory();
 
for (ItemStack item : inv) {
    if (item != null) {
        item.setAmount(-1);
    }
}
