wmcalliance/creepair

1.20.2 compatible Spigot plugin. Repairs creeper holes soon after they're formed, above ground, leaving your landscape clean for new players to explore.

Creepair

This plugin was originally coded by jamietech for us.

Basically, the goal of this plugin is to repair natural creeper-exploded blocks near, or above, ground level.

Much of the detail was coded by modwizcode and thanks to her, this plugin is fully functioning.

creepair's Issues

Customizable list of regenerating block types

Currently it's only dirt and grass, per the code.

Exploded blocks don't drop

This is a limitation of the current method, but basically non-natural blocks get destroyed, don't regen and don't drop. They should drop.

// Example code to reference (creepers destroy ONLY glass with this)
@EventHandler
public void onEntityExplode(EntityExplodeEvent event) {
    if (event.getEntity() instanceof Creeper) {
        for (Block block : new ArrayList<Block>(event.blockList()))
            if(block.getType() == Material.GLASS) {
                event.blockList().remove(block);
            }
        }
    }
}

When blocks repair randomly, blocks can get lost

This has two use cases;

1. falling blocks (sand and gravel) - when placed in the air, they fall, but don't get replaced a second time - so there are less blocks in the end than there were to begin with
2. 'safe' blocks (non-natural) when they drop their items - they get covered up by regenerating blocks and then lost inside the rebuilt hole
