first position set to（x,y,z）怎么回事？

The mod Single Player Commands + World Edit use the WoodenAxe as an editing tool with Leftclick for "First Position" and Rightclick for "Second Position" you can then type something like //set 1 (or //set stone) to change the whole area you selected with the wooden axe into stone (1 = stone, 2 = grass etc.)

哇 就是MCEdit里面的select的黄方块和蓝方块是吧 高端
