I am looking for a mod that would allow me to construct objects using the standard blocks in the game, but allow them to be buildable vehicles.
For example, I could build a large ship out of wood planks, fences, and wool blocks, and use the mod to allow it to be used as an actual ship and sail the water.
Or construct a zepplin out of iron, gold and diamond blocks and rule the skies in a mobile, metal, fortress.
Not sure if this can be done, or if such a mod exists, even in some small capacity. If it can be done, but hasn't been yet, I have a few more ideas to help flesh it out if anyone is interested in taking on such a thing.
