[starlogo-users] adress 1 turtle

[Jenny Volstorf]

Hello,


is ist possible to adress only one turtle,
randomly chosen out of the ones on the canvas?
(There is 1 turtle on every patch.)

I tried:

if who = (random (screen-width * screen-height))...

or

let [:x (random (screen-width * screen-height))]
if who = :x ...

but it doesn`t work.

Thanks,

Jenny Volstorf
