Solved Changing Spawner as it's placed.

Basically what my intentions are is to be able to change the TYPE of spawner it is as it's placed... So say I place a normal mob spawner I want it to change to a Blaze Spawner; here's what I have thus far!

Code:

    @EventHandler
    public void PlaceSpawner (BlockPlaceEvent e) {
        ItemStack hand = e.getItemInHand();
        if(hand.getType() == Material.MOB_SPAWNER) { //or test the block's type
            BlockState blockState = e.getBlock().getState();
                    CreatureSpawner spawner = ((CreatureSpawner)blockState);
                    spawner.setSpawnedType(EntityType.BLAZE);
                    blockState.update();
         e.getPlayer().sendMessage("You've placed a Mob Spawner!");
        }
    }

 

Code:java

 
        if(e.getBlock().getType() == Material.MOB_SPAWNER) {
            CreatureSpawner spawner = ((CreatureSpawner) e.getBlock().getState());
            spawner.setSpawnedType(EntityType.BLAZE);
            e.getBlock().getState().update();
            e.getPlayer().sendMessage("You've placed a Mob Spawner!");
        }

Just tested this and it does exactly what you're asking

 

Using that exact code? It sends me a message saying You've placed a Spawner but it doesn't change it..

After further investigations I've figured out it is one of my plugins - Thanks for your help regardless!
