My world mobile version of spider web can be obtained by digging with a sword that collects precise enchantments; If you don't collect the enchantments accurately, you will lose the connection when you dig the sword. When scissors dig, cobwebs will always fall off, no matter whether they are collected accurately or not, but nothing will fall off when digging with other objects.

Spider webs are naturally produced in fortress libraries, snow houses, abandoned villages [mobile version only] and abandoned mines.

The use of cobwebs:

Creatures can be generated in cobwebs. When the dead are in cobwebs, they won't be burned by the sun. Spider webs can also spread sunlight.

Building blocks can be placed on cobwebs, including billboards and paintings; Spider webs can slow down.
