CSP Unit 3 Lesson 9.7

Sometimes we need to use one loop after another loop to do what we want to do. This lesson demonstrates how this works by adding a loop that draws white circles to the colored circles code from the previous lesson.

The pre-placed code uses a repeat loop to draw the random colored circles, as in the previous lesson. It then adds a second loop to draw white circles (opacity = 50%). Experiment with the number of iterations to see how many it takes for the white circles to "erase" the colored circles. Does it make a difference if you change the opacity to 100% for the white circles? Compare your results with your neighbor's. |
