Solved Place block and then remove it after x seconds

Hello!

Can someone please help me figure this one out?

example:

Player places block x after y seconds remove x block from the map.

Thanks.

 

Place the block location and type in a hashmap, start a timer, remove the block (get location and type from hashmap) once the timer runs out.

Or did you want some code?

EDIT: I guess you could use the scheduler too.

 

dont use a timer as it will cause bugs whit bukkit (but like al threading isues, its unknown when (but it will be worrse)) use an sync task whit the schedular instead

 

Example code (if you want). Replace the PluginInstance with an actual instance of your plugin, and timeinseconds with an amount x seconds:

Code:java

@EventHandler
    public void onPlace(BlockPlaceEvent event)
    {
        final Player p = event.getPlayer();
        final Block b = event.getBlock();
        if(!p.hasPermission("can.I.Build.Here")) // Or whatever
        {
            Bukkit.getScheduler().scheduleSyncDelayedTask(this, new Runnable()
            {
                @Override
                public void run()
                {
                    b.setType(Material.AIR);
                    // Optional: give item back
                    p.getInventory().addItem(new ItemStack(b.getType(), 1));
                    // Optional: send message
                    p.sendMessage("You cannot build here");
 
                }
            }, timeinseconds*20L);
        }
    }

[Edit] You can also use b.breakNaturally();

 

I would use the shedular as well, but not with a hashmap.
I would create a new class that implements a runnable interface. The constructor should take a location.
In the run() method the block should be replaced with air.
HashMaps with actual Locations and Worlds etc. could result in memory leaks.

 

Xenon117 or just be lazy like me ;3

 

its better if you first give the item back to the player, and then remove the block, as your setting the block to air, and then giving air to the player,

 

ferrybig mmh true, a fail on my side xD

 

Nvm figured it all out thank you!

 

You would need an instance of the main class:

Code:java

Bukkit.getScheduler().scheduleSyncDelayedTask(Plugin instanceOfMainClass, new Runnable()
{
    @Override
    public void run()
    {
        // Whatever you want
    }
}, delayInSeconds*20L);
