From EngineHub.org Wiki
The MC1204 will cause customizable amounts of damage to a customizable set of entities, or optionally remove them.
- Third line: Radius, or Radius[=OffsetX:OffsetY:OffsetZ], or Radius[=OffsetX:OffsetY:OffsetZ=Damage]
- Example: '5' or '1=-2:5:11'
- Fourth line: List of entity flags.. If you prepend the line with a !, it erases the entity instead of damaging it.
- Example: '!PLAYER' would sense players and erase them from existance without dropping items. 'PLAYER' would just sense players and damage them the specified amount of damage. See more flags in the given link.
- High if detected
