I have several structure models, which are stored as instructions of type “put block of type A into location (X, Y, Z)”. They were created using Bukkit and now I want to re-use them in Sponge.
Most of the materials are of the original base materials that existed from the beginning, so Material.WOOD I believe is BlockTypes.PLANKS since the specific types are BlockStates. STEP is more than likely whatever the basic slab block was initially, which I believe is WOODEN_SLAB for BlockTypes. The rest look about right.
