Help for code

[PG1966]

I don't know why this code gives me an error.
Thanks in advance

It looks like the code is written in NetLogo language, but it's missing the to keyword before the action block, which is required to define a procedure or function. Here's the corrected code with the to keyword added:

to evacuation_model
  type: simulation 
  species {
    evacuee {
      initial_location: select_one(shelter)
      speed: 10
    }
    vehicle {
      initial_location: select_one(house)
      speed: 30
      capacity: 4
    }
  }

  grid {
    topology: torus
    shape: hexagon
    size: 100, 100
    resolution: 1
  }

  environment {
    shelter: patch kind: shelter
    house: patch kind: house
    road: link kind: road
  }

  experiment {
    duration: 3600
    steps_per_second: 5
  }

  to action 
    create shelter type: patch quantity: 1
    create house type: patch quantity: 1000
    create road type: link connect: all_to_all
    connect_patch_to_link(road, house)
    connect_patch_to_patch(shelter, house)

    create vehicle type: vehicle quantity: 200
    for (v: vehicle) {
      go_to(v, select_one(shelter))
    }
  end
end

Note that the action block now has a to keyword at the beginning, and an end keyword at the end to indicate the end of the procedure.

Dear, I highly recommend you to have a do at least one of the tutorials. There is nothing correct in your syntax, both in GAML or even in Netlogo. I do not know how you produce it. By curiosity, did you produce it using chatGPT ? Cheers Benoit Le mar. 14 mars 2023 à 07:45, Baptiste Lesquoy ***@***.***> a écrit :
