I have some point in a grid (c.f. fig1.png), I would like to connect them with links (c.f. network.png).
model sandboxDammAgent
global {
/** Insert the global definitions, variables and actions here */
init {
ask plot_cell {
create water_node{
location <- myself.location;
}
}
}}
grid plot_cell width: 4 height: 5 neighbours: 4 {
float water_need <- 1.0 ;
float water_taken <- (rnd(1000) / 1000) * 0.01 ;
aspect base {
draw shape color: #gray;
}
}
species water_node {
float water_available;
aspect base {
draw circle(1) color: #blue ;
}
}
experiment sandboxDammAgent type: gui {
/** Insert here the definition of the input and output of the model */
output {
display "grid 1" {
species plot_cell aspect: base;
species water_node aspect: base;
}
}
}
All my points agents need to know how is before and how is after in the network. Some one cane give me a lead ?
best regard

Thank you Patrick, so nice !
I don't really understand how graphs object work ! There is some information about graph manipulation ? is there some primitive dedicated to graphs like neighbors ?
Can I find documentation about that ?
