Half Slabs Count As Roof

But now that im putting a roof on it made out of half slabs ofcourse the spawn rate has decreased dramatically.

Half slabs count as roof.

Compared to cast in situ methods a half slab structure clearly saves man hours and material costs. You just saved 1 450 square feet of slab which is roughly 9 000 at today s price. 1 side needs a roof and the outside has to be empty or trans block to register as a house. You also saved around 1 700 square feet of shingles underlayment and roof decking which would cost about 3 100.

As verbs the difference between roof and slab. That means a total savings of around 12 000. Note that the inner height of spawn chamber needs to be 3 blocks or higher in order to trigger this bug. Now it takes several tens of minutes to spawn even a single mob.

Precast half slabs are an excellent choice for a floor structure in apartment houses villas and cottages. Elematic half slab long line is a fast and advanced technology for the production of non stressed and pre stressed half slabs of varying lengths and widths. Half slabs are a transparent block like stain glass and glowstone. Observe that the spawn rate has severely reduced.

I know wither skeletons are 3 blocks high so i placed the ceiling at block 4. Slabs on the roof do not affect the spawn rate at all. So there is a 3 block vertical space do wither skeletons require an extra empty space above their heads in order to spawn. Light level is well below 7.

You need a solid block above and below your door.
