I swear I have done this perfectly, but for some reason it doesn't work. The coordinates are indeed correct, and it is a dropper so there's something in the NBT tag. It is a server, command blocks are enabled, and everything else works. (I have also tried testforblocks
)
testforblock 14 8 -416 minecraft:dropper 0 {Items:[0:{Slot:1b,id:planks,Count:1b},{Slot:3b,id:planks,Count:1b},{Slot:4b,id:diamond_block,Count:2b},{Slot:5b,id:planks,Count:1b},{Slot:6b,id:stone_slab,Count:1b},{Slot:7b,id:stone_slab,Count:1b},{Slot:8b,id:stone_slab,Count:1b}]}
Should be the recipe
