Nearby Zombie Pigmen will get angry if a player harvests certain blocks.

These blocks also have a chance to explode when harvested.

The Fortune enchant makes the situation worse, the Silk Touch enchant makes the situation better.

Blocks affected are configurable in a JSON file.

Agro range, and all explosion parameters are confurable/disableable.

Example blocks.json

[
 {
  "BlockName" : "glowstone"
 },
 {
  "BlockName" : "someMod:someBlock",
  "MetaData" : "2"
 }
]

Config Options:

explodingore {
 # [range: 0.0 ~ 1.0, default: 0.25]

}

This mod was ported to 1.8.9 from one of my 1.7.10 mods Feed the Creeper Tweaks

The original idea was based upon a feature from the mod Nether Ores by SkyBoy and TeamCoFH, and was designed to complement it.

Feel free to use in Modpacks; notification is appreciated, but not required.
