5. Coding the cat- Adding Variables In order to set the move steps, create a integer data variable: “lineLength”. Once the variable is created, methods available to the lineLength will appear. Deselect the √ to hide the variable count. 1.Add “set (lineLength) to [x]” block 2.Demonstrate what would happen if lineLength remains the same the entire time. 1. (add the outer repeat only) 2. (Note it will create a box). 3.Discuss how the Top side and Right side initially are the same length, but the line mathematically gets shorter the complete the spiral. 4.Add the inner loop & “change(lineLength) by [-x]” PAGE 5
