[1.12.2] Check when explosion ends?

[TheAwesomeGem]

So there are events to check before an explosion starts and before explosion affects blocks. How to check when an explosion is done(including all the calls to the HarvestDropEvent)? I need this to check if the block harvested was from an explosion or not.

 

Basically I need a way to hook into this event:

 

/**
     * Called when this Block is destroyed by an Explosion
     */
    public void onBlockDestroyedByExplosion(World worldIn, BlockPos pos, Explosion explosionIn)
    {
    }

Hmmm. There isn't any nice way to do it.

 

If you are looking for explosions from a custom explosive then you could probably extend the Explosion class and override the behavior to give yourself a hook.

 

But if you want to handle vanilla explosions basically I think what you will need to do is to handle the explosion detonate event and copy  the list of affected blocks from the event and store it in a public field. Then in the harvest block event you should check if the block position is in that list. Then you should clear the copy of the list every tick, probably in a server tick handler.

Sadly, that's the way I am doing it but it's not working well if there are multiple explosions on top of each other. I wish there was a unique identifier for explosion. Thanks btw!

It should be unique for each explosion, the event should be called each time the explosion is called. So you can create a unique list of blocks from the affected blocks in each event.

 

What exactly are you trying to achieve anyway?

Change block drop if there was explosion. I know there is an event for each explosion but how do I tag which explosion is which? I am using Chunk capability to store a list of affected blocks from an explosion. However whenever the tick interval ends, I don't know which explosion caused the block affected. So sometimes i clear the affected blocks before it even gets to the HarvestBlock event where I customize the block drop.
