\n .create(“revjs:example_block”, “cloaked”)
\n .cloakAdvancement(“story\/smelt_iron”)
\n .cloakedBlockTranslation(“I’m stone stairs!”)
\n \/\/ Or just ‘cloakBlock(“stone_stiars”)’
\n .blockStateCloak(Block.id(“revjs:example_block”), Block.id(“stone_stairs”, { “facing”: “west” }))
\n .onCloak((cloakedBlock, cloakAdvancement, cloakBlock) => { })
\n .onUnCloak((cloakedBlock, cloakAdvancement, cloakBlock) => { })
\n})<\/p>\n
\/\/ Register a cloaked item
