How to cancel the explosion when the Wither reaches full health?

In 1.4, when a Wither reaches it's full health an explosion effect occurs and the surrounding land is destroyed. I'm working on my plugin 'StopWitherSpawns' which will be renamed to a more vague WitherManagement.

I have successfully stopped WitherSkulls from dealing terrain damage upon impact, but I can't find how to cancel the explosion from the Wither itself. What event would I need to cancel to do this?

Thanks in advance.

 

Code:

    @EventHandler
    public void onBlockDamageByWitherExplode(EntityExplodeEvent event){
                if(event.getEntityType() == EntityType.WITHER){
                    List<Block> blocks = event.blockList();
                    event.blockList().removeAll(blocks);
                }
            }

 

Tried this with no luck. Spammed my console with an NPE on lines 63 and 72 of my code.

Here is my class in question: https://github.com/MistPhizzle/Stop...hizzle/stopwitherspawns/StopWitherSpawns.java

Thanks for the help though, Any additional help is extremely appreciated.

 

Try copying what you did for WitherSkulls, and change it to just Wither.

 

Not even sure why I didn't think of that before. Fixed. Thank you so much!
