New Mexico Computer Science For All

1. New Mexico Computer Science For All Interface Input in NetLogo Maureen Psaila-Dombrowski

2. Interface Input • Can input Global Variables from the Interface tab of NetLogo • A quick way to change variable value • No recoding • Four ways: • Sliders • Switches • Choosers • Input Boxes

3. Sliders • Slider sets a global variable value to a NUMBER • Slider has a range of values • minimum value • maximum value. • Move the slider to the desired value • Increase by moving the slider to the right • Decrease by moving to the left • The current value of the variable is given on the right below the sliders

4. Create a Slider • Select slider in the drop down menu. Add it to the Interface tab • The edit dialog box automatically opens requiring • Global variable name • Minimumvalue of the variable • Maximum value of the variable • Increment • Initial value

5. Sample program – input a slider

6. Switch • Switches are used to set the global variable to a boolean value • On/Off • To Create • Select switch in the drop down menu. Add it to the interface. • The edit dialog box automatically opens requiring the Boolean Global variables name

7. Sample program – input a Switch

8. Chooser • Can set the Global variable to be any data type: strings, numbers, booleans, etc. • Lets you choose from a list of choices. • List is in a drop down menu.

9. Chooser • To Create • Select switch in the drop down menu. Add it to the interface. • Input the Global Variable Name • Input the list of choices

10. Sample program – input a chooser

11. Input Box • Input Boxes are used to enter global variables that contain strings, numbers or colors. • Strings can be • simple strings • commands/reporters (checks syntax) • Any type of number can be entered (more variety than sliders) • Color input boxes offer a color chooser using the NetLogo color table.

12. Input Box • To Create • Select switch in the drop down menu. Add it to the interface. • Enter Global Variable name • Choose variable type

13. Sample program – input a input box

14. Summary • Can input Global Variable values from the Interface tab of NetLogo • Can set the value in Four ways: • Sliders • Choose from a range of numbers • Switches • Boolean value • Choosers • Choose from a list of any data type • Input Boxes • Can be a number, string or color.
