nw:generate-star

nw:generate-star turtle-breed link-breed num-nodes optional-command-block

Generates a star network in which there is one central turtle and every other turtle is connected only to this central node. The number of turtles can be as low as one, but it won’t look much like a star.

If you specify an optional-command-block, it is executed for each turtle in the newly created network. For example:

nw:generate-star turtles links 100 [ set color red ]
