sety 0 - ( random 176 ) is in the onTouching area of a turtle, but it does
nothing when touching.
When touching... what?
It has to touch another turtle, not a color. These are the rules from the Help:
Turtles can be programmed to react when they touch any other turtle. In the
OnTouching field, type the instruction to run when the turtle touches (or is
touched by) another turtle. Any change in the state of a turtle that results
in a "collision" that you can observe visually will trigger a collision
detection: fd, bk, home, setpos, drag and drop, setsize, etc. Both the
"active" turtle (the one that is touching, due to a change in its state) and
the "passive" turtle (the one that is touched) will react to the collision and
do whatever they are instructed to do.
