It won't rotate while holding down left click
Oh cool.
Do you mean specifically a larger grid than normal or just any grid?
Any grid would be cool. The idea would be to allow the user to specify the grid using a command- like /setgrid x y z
The ghost brick would align itself to this grid whenever you clicked somewhere.
The grid offset could be handled by the location of the brick.
For example, say I was building a lot of terrain using 4x4 cubes and I wanted each cube to be aligned. First of all, I would put a 4x4 cube in the destination I want the grid to be aligned to. Then I enter the command /setgrid 4 4 10 (The size of the 4x4 cube).
If I didn't care about the height offset, then I would just do /setgrid 4 4 1.
From there I would just build without having to worry about being too precise, which is what would make building a lot easier.
To revert to the default grid, I would just do /setgrid 1 1 1.
Does that make sense?
I think he wants to be able to set a larger grid than normal for the sake of doing easy terrains.
