Making turtles wait x number of ticks - wait

Question

Part of what I am trying to do is make a breed of turtles move around, but when one reaches its destination that turtle waits for a certain number of ticks before continuing ? Also is it possible to make turtles wait for different number of ticks depending upon their destination ( different patch colors). Is it a case of making a turtle breed or global variable to count the number of ticks? The hopefully relevant code is below.

Answer 1

You are right, this can be done by making the turtles count the number of ticks they have been on a patch. Also this has to be a turtle variable and not a global variable since each turtle will have a different value for this
The approach, I have used is this:
Once the turtle arrives at its destination record the ticks (the global variable which records the number of ticks that have passed till now) into a turtle variable say ticks-since-here. This works like a time-stamp.
On each successive tick check the difference between the current-time ticks global variable and the ticks-since-here turtle variable. If this becomes greater than the number of ticks the turtle is allowed to stay on the patch, let it choose and move to the new destination.
