Beetle Blocks is a graphical blocks-based programming environment for 3D design and fabrication. It allows writing scripts to control a beetle that can place 3D shapes and extrude its path as a tube, which can then be used to make a 3D print. Beetle Blocks is made by Eric Rosenbaum and Duks Koschitz, with software development by Bernat Romagosa and Jens Moenig. It is based on Scratch and Snap!.
|Note:||Beetle Blocks is alpha software and is currently in development.|
Beetle Blocks has most of the same block categories as Scratch. In any of the categories, you can right-click a block and hide it. If you wish to restore the block you must right click the background and select "show primitives". Beetle Blocks has the following blocks, in addition to those found in Snap!:
go home :: motion
move (1) :: motion— Moves the specified number of steps.
rotate [z v] by (15) :: motion
go to x: (0) y: (0) z: (0) :: motion
set [x v] to (0) :: motion
change absolute [x v] by (1) :: motion
set [z v] rotation to (0) :: motion
point to x: (0) y: (0) z: (0) :: motion
([x v] position :: motion)
([z v] rotation :: motion)
push position :: motion— Saves the beetle's position so it can be used later.
pop position :: motion— Restores the position most recently saved with the block above and removes it.
set scale to (1) :: motion
change scale by (0.5) :: motion
(scale :: motion)
reset :: #505050— Clears all rendered graphics.
cube Dim. (0.5) :: #308997
cuboid l: (1) w: (0.5) h: (0.3) :: #308997
sphere Dia. (0.5) :: #308997
tube l: (2) outer: (1) inner: (0.5) :: #308997
text [hello] H: (1) W: (0.5) :: #308997
2D text [hello] size: (10) :: #308997
start drawing [lines v] :: #308997
stop drawing :: #308997
start extruding [curves v] :: #308997
stop extruding :: #308997
set extrusion Dia. to (1) :: #308997
change extrusion Dia. by (1) :: #308997
set [hue v] to (50) :: #653d7a— Sets the hue, saturation, lightness, or opacity of the beetle's color.
change [hue v] by (10) :: #653d7a
(color [hue v] :: #653d7a)
request user input  :: #828282— Asks a question and stores the answer in
(answer :: #828282).
Make a Variable
The "make a variable" button takes you to the variable creating dialogue. In this dialogue you can input the variable name and select if you want this variable to be available for all sprites or only for the one that you are currently creating the variable in.
Make a Block
The category My Blocks has no blocks until one is created. To create a block one must click on the Make a block button. This will open up a dialogue box which will give you a selection of customization options.
- The first one gives you a selection of category. The color of the block varies according to the category that has been chosen.
- In the second one you can select a name for your block, which will be written on the block.
- For the third option you have the ability to select between three block types: Command, Reporter and Predicate.
- The fourth final option is whether the block should be available/visible only for the sprite that the block is currently being created in or whether it should be available/visible for all sprites.
