Inventory & GUI

Hotbar​

mc.selectHotbar(1)            // select slot 1 (1-9)
let slot = mc.getSelectedSlot()  // current slot number (1-9)

Inventory Query​

mc.hasItem('minecraft:diamond', 64)    // has at least 64 diamonds?
mc.getItemInHand()                     // → {id, count, name, durability, ...}
mc.getItemOffhand()                    // offhand item
mc.getItemInSlot(slot)                 // slot 0-35
mc.getAllItems()                       // → [{slot, id, count, name, ...}]

GUI Operations​

mc.isGuiOpen()                         // → boolean
mc.getGuiTitle()                       // → string
mc.closeGui()                          // close current screen

mc.getContainerSize()                  // total slots in container
mc.getContainerType()                  // 'chest' | 'crafting_table' | 'furnace' | ...

Clicking Slots​

All slot operations use the raw slot index within the container.

mc.clickSlot(slotId)                   // left-click slot
mc.clickSlotRight(slotId)              // right-click slot
mc.clickSlot(slotId, button)           // 0=left, 1=right, etc.
mc.moveItem(fromSlot, toSlot)          // move item within container
mc.quickMoveItem(slotId)               // shift-click (to/from inventory)

Crafting​

mc.craft()                             // click result slot (craft 1)
mc.craftAll()                          // shift-click result slot (craft max)
