Options for hooking into BlockFalling -> onStartFalling and onEndFalling

[DougLazy]

Hey I'm going through my options, to hook into BlockFalling. To describe my need, it would be solved, for example, if forge had an event for BlockFalling descendants like:

 

    @SubscribeEvent

    public void onStartedFalling(BlockFallingEvent.FallStartedEvent event)

    {

    }

 

(And the EndFalling of course.)

 

This would allow me to write code as if I'm in BlockSand.onStartFalling(EntityFallingBlock fallingEntity), but there are other ways.

 

My three options:

 

1. Write that new BlockFallingEvent class and PR into Forge itself, seems possible, but I've no idea.

2. Instead unregister vanilla BlockSand and register my own. Like in this post.

3. Go down the ASM route, which seems like both overkill and a bad idea in general.

 

Are there other options before I go for #2 ? I don't think #1 is realistic for me for the moment.

 

Thanks,

Why do you need these events? What is your goal (describe it as what the player observes)

[DougLazy]

I guess the core concept that relates can be simplified to this behavior:

 

The player drops sand and it falls longer than some threshold (say 64 blocks), when it lands I check the block it lands on and transform that block based on some made up mappings I'm playing with.

 

So I think I can do this with my own sand, but I can't see a straight forward route with the vanilla sand.
