Netlogo: move to a specific patch

I am gonna ask a simple question. I have workers and patches. Workers want to go to a specific patch, labeled by an id. I tried the following code, but it does not work. Can someone help me? Thanks

workers-own[selected-area]
patches-own [id]

ask workers [
move-to one-of patches with [id = selected-area]]
Solution

  • In your example you have two important variables. selected-area, which is a turtles-variable, and id, which is a patch-variable. Each agent (patch or turtle) can access its own variable, but not those of the others. The problem here, is that you ask the patches to compare id to selected-area, but patches don't have a variable called selected area so the program doesn't work. The current structure of your program is:

    1. Observer gives command to all agents (2)
    2. Every agent gives a command to all patches (3)
    3. Every patch tries to compare id to selected-area

    A very nice tool for these sorts of situations is myself. Myself refers to the agent that asked you to do what you are currently doing, the one who is 1 level above you. In this case, it will allow the patch to check the turtle's variables.
