How to move turtles between neighbors on a hex grid? - netlogo

Question

I want to ask how to move turtles to their neighbors. ( the houses are hex cells)
I tried to make it but give me an error.
;;;;;;;;;;;;;to make houses or the hex cells
to setup-cells
set-default-shape cells "hex"
ask patches
[ sprout-cells 1
[ set color grey
set size 1.2
;; shift even columns down
if pxcor mod 2 = 0
[ set ycor ycor - 0.5 ] ] ]
ask cells
[ ifelse pxcor mod 2 = 0
[ create-links-with cells-on patches at-points [[0 1] [1 0] [1 -1]] ]
[ create-links-with cells-on patches at-points [[0 1] [1 1] [1 0]] ] ]
ask links [ hide-link ]
end
;;;;; I add turtles to their houses
to setup-population
ask patches [
sprout 2
if pxcor mod 2 = 0
[ set ycor ycor - 0.5 ]]
end
my question is how to move this turtle to the link neighbors
I tried to do this
to move
ask turtles[
if ( random-float 1) < 0.03 [
move-to one-of link-neighbors
fd 1 ]]
end
but this always give me an error
move-to expected input to be agent but got nobody instead

Great question. It's too bad this isn't covered in Hex Cells Example (the code example you seem to be working from). Or maybe we should have a separate Hex Cells With Turtles Example.
First, you should make a separate breed for the turtles that live in the houses, so you can refer to them separately from the cell turtles. Suppose you call them people:
breed [people person]
then you should change sprout 2 to sprout-people 2.
As for implementing movement, the code you tried doesn't work because people don't have link-neighbors. It's the cells that have link-neighbors.
So instead of:
move-to one-of link-neighbors
you must write:
move-to [one-of link-neighbors] of one-of cells-here
If you want the people to face in the direction of movement, then it's:
let target [one-of link-neighbors] of one-of cells-here
face target
move-to target
