Drawing Shapes

Commands like forward and up draw one line of blocks at a time, which is great for paths, outlines, and anything you want to watch grow. When you know the shape you want, Enu can draw the whole thing in one command.

Shapes are drawn where the drawing turtle is, facing the way the turtle faces, in the current color. Move the turtle with the normal drawing commands (use drawing = false if you don't want to leave a trail on the way), or tell the shape exactly where to go with at.

box

box width, height, depth draws a solid box:

box 5, 3, 8

Make it hollow with fill = false, which is an instant room. Erase a couple of blocks for a doorway and you've got a little house:

box 9, 6, 9, fill = false
box 2, 3, 1, at = vec3(4, 0, 0), color = eraser

You can also draw a box between two corners, which is handy when you know coordinates instead of sizes:

box vec3(0, 0, 0), vec3(9, 4, 9)

ball

ball size draws a sphere, size blocks across, centred on the turtle:

color = red
ball 9

Hollow balls make good domes. Draw one, then erase the bottom half, or bury half of it in the ground. sphere is the same command with a fancier name.

can

can size, height draws a cylinder, standing on the turtle's spot:

color = green
can 7, 12

Perfect for towers, tree trunks, columns, and cans. cylinder is the same command with more syllables.

wall and floor

wall length draws a wall heading the way the turtle faces, 4 blocks tall unless you say otherwise:

wall 10       # 10 long, 4 tall
wall 10, 8    # 10 long, 8 tall

The turtle ends up at the far end of the wall, so turning and drawing another wall makes a perfect corner:

color = brown
4.times:
  wall 15, 5
  turn right

That's a fort. You're welcome.

floor length works the same way, but flat. It draws a square slab unless you give it a different width:

floor 15      # 15 x 15
floor 15, 10  # 15 deep, 10 wide

Like wall, it leaves the turtle at the far edge, ready for the next piece.

place

place x, y, z puts a single block at exact coordinates without moving the turtle:

place 3, 0, 5
place 3, 1, 5, red

Coordinates are relative to the build's own space, not the world.

Drawing somewhere else

Every shape takes an at to draw at exact coordinates instead of at the turtle:

ball 5, at = vec3(0, 20, 0)      # a ball floating overhead
can 3, 30, at = vec3(10, 0, 10)  # a column off to the side

Colors and erasing

Shapes use the current color, or take one directly:

box 5, 5, 5, color = green

eraser is a color too, so shapes can carve as well as build. A classic move is drawing a solid box and erasing a doorway:

box 9, 6, 9
box 2, 3, 1, at = vec3(4, 0, 0), color = eraser
