02 Importing 3D models of thoughts into StarLogo TNG.

This guide will show you how to import 3D models of thoughts into a StarLogo TNG project.

Before you start this guide you should look at Getting Started with StarLogo TNG.


What if thoughts had different shapes, colours and textures?

Importing .obj files…

Obj is a popular 3D file format. You can export .obj files from most 3D programs, including Blender.

– Download and unzip 3D models of thoughts from the 3D models page at Flunstellas.org


– make a new folder called ‘thoughts’ at the location shown below.  Copy the unzipped 3D flunstellas models and the folder they a in, into the thoughts folder.

– Mac = Applications/StarLogo TNG/Models

-Windows = Program Files\StarLogo TNG/models

Importing 3D Models

In the Blocks Window…
– Click on the ‘Edit Breeds’ tab, to the right of ‘My Blocks’.

Adding Breeds

StarLogo TNG is populated by breeds, when you create a breed, your simulation or game can choose to use 1 or 101 of that breed, and any instruction you give to one, will be given to all.


In the Breeds window.
– Click ‘New’ and navigate to the ‘Thoughts’ tab, below the top layer of thumbnails.
– Choose one of the models with a grey background and large ‘B’ in the Thumbnail.
– Give that breed of thought a name by typing under its thumbnail.
– Click ‘Ok’


Creating a new Set Up Block

Drag a “Create Do” block out onto the “Set Up” page, and place it in your new “Set Up” block, underneath Clear Everyone. Each “Create Do” block has the name of its breed, so yours will be called “Create ‘MyBreedsName’ Do”

The “Create Do” block is different to the “Create” block, as it allows us to tell the breed to ‘do’ certain things, as it is created, but for now we will leave the “DO” socket empty.


Viewing the SetUp in the SpaceLand Window

In the 3D ‘SpaceLand’ window.
Click on the ‘SetUp’ block at the bottom left of the window.

Experiment with different numbers of thoughts and using different “Random” numbers, which are in the ‘Maths’ Drawer, to set traits such as size, altitude, heading, xcor, ycor & transparency (0 = solid, 100 = transparent).


As well as the guides on this website, the StarLogo TNG website has a great set of tutorials.
