Unbreakable addon

What does it do?

With Unbreakable addon, you can make a portal indestructible from specific sources such as creeper explosions, or make the portal only breakable by destroying its blocks (and not the inside part of it)

How is it configured?

Addon:
  Unbreakable:
    - '<input>'

<input>:

• PLAYER_INSIDE # player attacks the portal inside (portal entity)

• PLAYER #the destroyer was a player (by breaking the blocks)

• ENTITY #the destroyer was an entity (creeper by explosion etc)

• DISPENSER #a dispenser destroyed the portal (currently dispensers do not break the portal)

• PISTON #a piston destroyed the portal

• BLOCK_PHYSICS #a block changed due to block behavior (dirt becomes grass etc)

This option is a list. You can add more options by adding a new line and then another - <input>
