Falling Block Land Event?

Hello, I'm working on changing sand physics, so sand collapses to sides, if there's space. I've got the code all working. It executes when a player places a sand/gravel block, but I need to find a way to execute it, when the sand/gravel block falls, to check if there's any more free space around. Any ideas?

 

Limeth So you're saying if i were to place a block of sand it would fall but then move to the right/left if there was space?

 

GodzOfMadness Exactly.

 

Limeth Not sure if this would work at all but you could try this,
fallingBlock.getLocation().getBlock().getRelative(BlockFace.FACE);
And lets say if fallingBlock.getLocation().getBlock().getRelative(BlockFace.EAST).getType().equals(Material.AIR);
then do something like change the velocities x/z to that direction.

 

GodzOfMadness Where am I supposed to put this code though? That's why I need the event.

 

EntityChangeBlockEvent checks if a block is about to fall.
for example:

Code:

    @EventHandler
    public void onBlockFall(EntityChangeBlockEvent event) {
        if ((event.getEntityType() == EntityType.FALLING_BLOCK)) {
            //block falling
        }
 
    }
