Not a draggable, neither a motor, but a real free block. A free block that moves when pushed, lifted, etc. But... it must not stick or attach to another metal blocks. In short, the free block must not be a metal.
Wouldn't using free motors suffice? I would rather that Martin focus on implementing something else if it will just be the same thing, except that it can't be attached to metal blocks. Would you be able to attach it to other "real" free blocks and make them move as one?
I don't think so that the lifting n moving part could be achieved at same time due to 2D senstivity touch screen devices
You are full of imagination! But the only problem of this is it can win easily, no matter where you put the win block.
