In previous lessons we added parameters to the drawStar and drawGrass functions to enable us to draw them in multiple locations. In this lesson we will add another parameter to the drawGrass function that will allow us to specify the width of the grass drawn. To start, load your saved file from Lesson 8.12. (Click on the "File" button" at the top left of the RoboBlockly window.)

Using your code from Lesson 8.12, modify the drawGrass function so that it uses a third parameter, named grassWidth, that can be used to specify the width of the grass blades drawn. Then add function calls to your program to draw grass in several locations with different widths. Don't forget to save your work to the cloud in an xml file named "YourName_Lesson8.13"! |
