Commentary
This project shows two of the many ways to track the order that a group of turtles are selected in.
The turtles are the three shapes (fish, flower and star) located in the upper right. The task is to select the three turtles in the correct order.
Dragging the turtle
One way we can do that is to have the user drag the turtles onto different color regions. When all the turtles are placed the user clicks the
done button. The color under each turtle is checked (using
colorunder) and the program can then proceed depending on the outcome.
Clicking the turtle
The second way this can be done is to have the user click on each turtle in turn. When all three turtles have been clicked the order they were clicked in is checked. In this demonstration we only allow each turtle to be clicked once but it would be just as easy to allow multiple clicks.
