Secondary grid

I went into all of the small details in my last post but I don’t think it went through so here I am. I propose adding a block that makes a secondary grid in the Minecraft world. the difference in this grid would be its ability to move in the existing Minecraft grid. Players would be able to place blocks around this block making allowing them to make their creations move. -problems to work through- You would have to devise a way that allows players to place blocks in this grid without interrupting the smooth gameplay of Minecraft. You would have to make a system in which the players could determine what direction the grid is moving in. And finally there would have to be some way of stopping the players creations from collisions in the normal grid while they are moving perhaps looking at where the two grids intercept that also have blocks in them? And finally if it would be to much of a problem in normal gameplay perhaps it would be better to add it into the gameplay of people who are using commands? This would allow for some pretty cool and moveable creations in the Minecraft world and we’ve seen just how much players are wanting to see creations that are moveable from the way they use add-one commands and Redstone creations to do it.
