3. Connections

Formulation

• Mapping the network of connection

Model Definition

In this final step, we will display edges between cells that are within a given distance.

Cells update

We add a new reflex to collect the neighbors of the cell that are within a certain distance:

species cells skills:[moving3D]{
...
    reflex compute_neighbors {
        neighbors <- cells select ((each distance_to self) < 10);
    }  	
}

Then we update the cell aspect as follows. For each element (cells) of the neighbors list, we draw a line between this neighbor's location and the current cell's location.

aspect default {
    draw sphere(environment_size*0.01) color: #orange;
    loop pp over: neighbors {
        draw line([self.location,pp.location]);
    }	
}
