Lesson 4. Programming in Minecraft. Command setBlocks
To set a single block, we used the setBlock () function, but there is one more function - setBlocks (). It allows you to create a rectangular parallelepiped, which is also called a cuboid, consisting of several blocks at once. The length, width and height of the cuboid may be different. The setBlocks () function allows you to fill large amounts of space with blocks. Calling this function, give it two sets of coordinates and a block type. The first set of coordinates must correspond to the position of one corner of the cuboid, and the second one to the position of the opposite corner.
