Make Items Not Despawn

I'm pretty sure it takes items five minutes and then they despawn. Is there a way to make it so that they don't despawn? Actually not any item, I have a line that spawns an item in my code, is there a way to make it so that just that item doesn't despawn? And no I can't just spawn a new item after five minutes, because a player would pick up that item and I can't have it respawn so that there's unlimited of it.

 

There's a nice event called ItemDespawnEvent, and it's cancellable. http://jd.bukkit.org/apidocs/org/bukkit/event/entity/ItemDespawnEvent.html

 

Thanks

 

Log the entity object and listen for the event gregthegeek posted, then compare the object that was trying to despawn, if it is the same object that you logged, deny the event, else allow it

 

I need to do that, but I don't know how.

 

add the item to a list/map then compare it to the item on the itemdespawn event

 

I suck at HashMaps =/ how would I go about doing that?

 

What're you using it for? You could make an ArrayList to save them in like this

Code:

public ArrayList<Integer> items = new ArrayList<Integer>();
 
@EventHandler
    public void despawn(ItemDespawnEvent event){
        if(items.contains(event.getEntity().getItemStack())){
            event.setCancelled(true)
        }

I'm just guess with this. I have no idea what you'd put in the array list...

 

Yeah me neither

 

Could you post more of your code? Specifically, where you spawn the item in

 

This is where I spawn the item:

Code:java

World world = Bukkit.getServer().getWorld("world");
int x1 = 10;
int y1 = 45;
int z1 = 4351;
final Location loc1 = new Location(world, x1, y1, z1);
final ItemStack item1 = new ItemStack(Material.MELON, 1);
Bukkit.getServer().getScheduler().scheduleSyncDelayedTask(plugin, new Runnable() {
    public void run() {
        Bukkit.getServer().getWorld("world").dropItemNaturally(loc1, item1);
        Bukkit.getServer().broadcastMessage("[" + ChatColor.LIGHT_PURPLE + "Apocalypse" + ChatColor.RESET + "] " + ChatColor.RED + "Reloading data, incoming lag.");
        Bukkit.getServer().reload();
    }
}, 100L);

 

Why are you triggering reload on the entire server ? Some plugins might break and most of all you're prone to memory leaks, using reload is a really bad idea.

Also, I am unsure if cancelling ItemDespawnEvent works properly... you should test it before relying on it.

And also, hashmaps are too easy... key-value pair.
Basically you asign values to keys and then to get a value you give it the key, pretty simple stuff.

 

I've never used a HashMap before =/ Also, the reload thing was a test and I forgot to take it out.

D: I have no idea where to start. First of all, how do I edit my code so that when the item is spawned it logs something to the hashmap, an int would be nice.
