3D live coding, implemented in Nim.

Enu lets you build and explore worlds using a familiar block-building interface and a Logo inspired API. It aspires to make 3D development more accessible, and will eventually be usable to create sandalone games.

Enu isn't ready for public testing, but it's getting close. MacOS, PC and Linux version of Enu 0.1 should be ready on Friday, Nov. 6th 2020.

See the Enu 0.1 demo video:

• Enu 0.01 Intro and Demo
• Introducing Enu - NimConf 2020

Draw a square:

forward 10
right 10
back 10
left 10

or:

4.times:
  forward 10
  turn_right()

Create a twisting tower:

var
  length = 20
  height = 50

height.times:
  left length / 2
  back length / 2
  4.times:
    forward length
    turn_right()
  forward length / 2
  right length / 2
  turn_right 5
  up()

Draw randomly:

up 10
forward 10
(50..100).times:
  forward 2..5
  turn_right -180..180
  up 0..2

Set the color to blue randomly with a 1 in 50 chance. Otherwise set it to white:

if 1 in 50:
  color = blue
else:
  color = white

or as a one-liner:

color = if 1 in 50: blue else: white

Move forward 10 times, cycling through colors:

for i in 0..9:
  next_color()
  forward()

or:

10.times:
  color = cycle(red, black, blue)
  forward()

$ nimble build
$ nimble edit

When Godot has finished importing assets, you can launch Enu with the play button, F5, or with nimble start.

Enu temporarily requires a custom Godot version, which lives in vendor/godot. This is built as part of nimble prereqs.

Windows and Linux targets aren't well tested currently, and may not work.

• ESC - toggle mouse capture and to dismiss editor windows
• W, A, S, D - move around when mouse is captured
• Space - jump. Double jump to toggle flying. Hold to go up while flying
• Shift - go down while flying
• ~ - toggle the console
• Cmd+S - save and reload the current script
• F - toggle fullscreen
• 1 - 7 keys - Change action. 1 to code, 2 - 6 for blocks and 7 for objects
• Mouse Wheel Up/Down - switch between blocks
• CTRL - hold to temporarily capture the mouse and fly. Mainly so you can change your view without having to switch away from what you're doing.

Enu 0.1 will only feature 5 block types/colors, and 1 object model (a robot). This will be greatly expanded in the future.
