create a minecraft item that has the following description: 'make me an item that can do 3 things, build a wall, build a platform, and build a staircase, they should all be in a 5x5 configuration. To change materials from wood planks, to bricks, to iron blocks, you shift and right click. To build between the three different types a flat platofrm, wall, or stairs, it should be a new hotkey to cycle. so if you press the f key while holding the item, it cycles. When in survival mode, make it actually use the blocks.'
Edit v2: make the want when i shift left click cycle between the platform, wall, and stairs
