Help with Bukkit API - I dont know what to use in order to accomplish a task

I am relitively new to Java Programming, and I need help with a problem I am having.

I do not know how to wait and then open a door. I currently have code that can open and close a door, but I do not know how to schedule an event. Help is appreciated. If you need more info, let me know what to tell you.

Thanks

As in delay it with a timer?

There are four different types of scheduling: syncrhonous delayed/repeating, and asynchronous delayed/repeating. Delayed occurs only once, while repeating, well, repeats. For your purposes you want this (going off of memory so may be slighly off):

Code:

getServer( ).getScheduler( ).scheduleAsyncDelayedTask( yourPlugin, new Runnable( )
{
    void run( )
    {
        //Your open/close code. Or call the method that does it.
    }
}, ( long )#ofTicksUntilEventFires );

#ofTicksUntilEventFires is how long to wait. There are 20 server ticks a second.

How do I pass a block to that run()

 

Code:

final Block block = yourEvent.getBlock(); // Declare a final variable that holds your block
getServer( ).getScheduler( ).scheduleAsyncDelayedTask( yourPlugin,
new Runnable( ) {
    void run( )
    {
        //Your open/close code. Or call the method that does it.
        // You can use that final variable here
    }
}, ( long )#ofTicksUntilEventFires );

There are other ways as well, for example implementing Runnable in an own class and using a constructor that accepts a Block object.

Code:

    public void onPlayerInteract(PlayerInteractEvent event) {
        Action action = event.getAction();
        Player player = event.getPlayer();
        Block block = event.getClickedBlock();
        this.block2 = block;
        int type = block.getTypeId();
        int sec = plugin.getClosingTime();
        BukkitScheduler scheduler = plugin.getServer().getScheduler();
        scheduler.scheduleSyncDelayedTask(plugin, new Runnable()
        {

                      public void run() {
                        Block upperblock = this.block2.getFace(BlockFace.UP);
                        if (this.block2.getData() == 4)
                          this.block2.setData(0);
                        else if (this.block2.getData() == 3) {
                          this.block2.setData(7);
                        }
                        if (upperblock.getType() != Material.WOODEN_DOOR) return;
                        if (upperblock.getData() == 12)
                          upperblock.setData(8);
                        else if (upperblock.getData() == 11)
                          upperblock.setData(15);
                      }
                    }
            }
        , sec * 20);
    }

This is my code and I get an error in eclipse saying

 

@alta189

Where are you creating the block2 object? Looks like it is out of scope. Also you have some typos like:

Code:

this.blcokk

You would want to do something like this :

Code:

    @Override
    public void onPlayerInteract(PlayerInteractEvent event) 
    {
        //Was a door clicked?
        if( event.getClickedBlock( ).getType( ).equals( Material.WOODEN_DOOR ) )
        {
            final Block block2 = event.getClickedBlock( );
            
            plugin.getServer( ).getScheduler( ).scheduleSyncDelayedTask( plugin, new Runnable( )
            {
                public void run( )
                {
                    //Make sure it is still a door
                    if( !block2.getType( ).equals( Material.WOODEN_DOOR ) )
                    {
                        return;
                    }
                    
                    Block upperBlock = block2.getFace( BlockFace.UP );
                    
                    if( block2.getData( ) == 4 )
                    {
                        block2.setData( ( byte )0 );
                    }
                    else if( block2.getData( ) == 3 )
                    {
                        block2.setData( ( byte )7 );
                    }
                    
                    if( upperBlock.getData( ) == 12 )
                    {
                        upperBlock.setData( ( byte )8 );
                    }
                    else if ( upperBlock.getData( ) == 11 )
                    {
                        upperBlock.setData( ( byte )15 );
                    }    
                }
            }, plugin.getClosingTime( ) * 20 );    
        }

If you need to update a block outside the scope of run() ( such as one owned by the playerListener ), you could always make and call a method such as updateBlocks( block2, upperBlock ).

Thanks for all your help!!! I got it working now!
