Craft a machine to project simple wooden block bridges across a gap. Use the crafting grid to fill that machine with eight items from the wood group. Place the full machine, right click to rotate it into the correct direction, then left click to shoot up to eight blocks in that direction, as long as there is a space for them. Once used it can be refilled and used again.
This mod is destined to be enhanced in the future as and when I have the time.
