Cave Air not handled like air by most modules.

[Bloo-dev]

Most modules don't treat Cave Air the same as air. As a result modules with air checks don't work as intended in caverns, natural ponds, ravines, dungeons…

Expected Behavior

The Module should treat Cave Air just like normal air.

Current Behavior

Cave Air is treated like any non air block.

Possible Solution

Create a block tag #air, maybe even include it in the base.

Affected Modules (extend this list in the comments)

Shroomites (spores see cave air as a solid block)
Phantom Scarecrows (rockets explode in cave air)

[misode]

Including common tags (like #air) in the base seems like a bad idea because that's going to cause incompatibility issues.

[Kroppeb]

I think we should include a #air as many modules might have problems and Mojang still hasn't added a tag themselves.

List of modules testing for air:

• Boots of Ostara:
  • Crops won't be planted on newly placed farmland in caves: gm4_boots_of_ostara\data\boots_of_ostara\functions\active.mcfunction
• Custom Crafters: Not affected as the check is for when a crafter is broken, will always be air
• Phantom Scarecrows:
  • rockets explode in cave air: gm4_phantom_scarecrows\data\phantom_scarecrows\tags\blocks\traversable.json
• Pig tractors: same as above but it's littered with air checks, I think some of them might be able to be deleted
• Shroomites:
  • spores see cave air as a solid block: gm4_shroomites\data\shroomites\tags\blocks\shroom_rootable.json
• Zauber Cauldrons:
  • Idk what's happening with the poison potion here so idk if it's affected: gm4_zauber_cauldrons\data\zauber_cauldrons\functions\recipes\potions\poison.mcfunction

[Bloo-dev]

Yes, Zauber Cauldrons is affected. Putting up the cauldron in a cave will prevent cobwebs from spawning upon recipe execution (poison IV potion). Though this will only work once since breaking the cobwebs would place air again

This other type wouldn't really affect much, but minecraft:void_air as well

Reopen as this was only patched in 1.13
