Hi!

Here is my unique macro that I developed specifically for the Minecraft game. I want to note that it is the most convenient and fastest among all existing macros.

It is very simple to use:

1) Stand on the edge of the block you want to build and hold down the Shift key.
2) Point the mouse cursor at the approximate center of the block.
3) Release the Shift key and run the macro.

The macro will automatically build the necessary structure, without having to put the first block manually. But please note that the possibility of building only straight roads is limited so far. In the future, I plan to add support for diagonal construction and the creation of double blocks.
