Solved Place block when destroy another block

The event is called prior to the block breaking, so if you set the block in the event handler itself, you will actually be breaking the block you set it to in-game. It looks like this:

Start breaking block -> BlockBreakEvent called at the end -> Your listener runs, setting the new block type -> the server breaks the block, which you just set to LAVA

To make sure you set the block AFTER the server actually breaks it, you need to use the Bukkit scheduler or schedule a BukkitRunnable to delay setting the block itself 1 tick.

 

Show your full code please. Also, for ENUMs you should use == Material. From what I understand you're trying to replace any broken obsidian to lava, right?

 

You need to change to block to lava 10 ticks (for example) later than the block break event

 

Code (Text):

@EventHandler
    public void onBreak(BlockBreakEvent e) {
        if (e.getBlock().getType() == Material.OBSIDIAN) {
            // Setup a bukkit runnable that will run e.getBlock().setType(Material.LAVA); about 10 ticks later
        }
    }

 

Delay the setting of the block using the scheduler or a bukkitrunnable

 

Code (Text):

new BukkitRunnable() {
           @Override
           public void run() {
               // What you want to schedule goes here
           }
           
       }.runTaskLater(yourplugininstance, timeinticks);
