create-links-with is a turtle procedure that creates a link between the current turtle (self) to every member of a provided agentset.

ask turtles [
    create-links-with other turtles-here
]

Notice that we use the other primitive in our code because if we did not use other, our code would give an error. NetLogo shows this error because the turtles-here primitive reports all the turtles in a model, including the turtle who is trying to create the links, but a turtle cannot create a link with itself. So, do not forget to use the other primitive when you are using similar agentset reporter primitives such as in-radius and turtles.

Also keep in mind that this primitive is used to create multiple links at once, so you need to provide an agentset. If you want to create a link with just one specific turtle, you should use the create-link-with primitive.

In the model example below, we use the create-links-with primitive to simulate contact tracing. Every time two people are on the same patch, a new link between them is created. Then, the trace-back button/procedure uses the links between the individuals to trace back the people who may have been exposed to an infectious person.
