Sample text

Iteration” is the term we use in programming to represent a complete single step in a loop, where all the indented code executes once. When the logical (or “conditional”) test is no longer true–the rotation angle is no longer less than the maximum leg angle–control leaves the inner while loop and proceeds to the next line in the program. The last few lines of pseudocode reset the leg rotation angle and then determine which leg should be the active leg. I used if and else statements to ensure that the active leg keeps changing after each skating stride.

However, there is one new command, arc(), toward the bottom of the code that probably needs some clarification. arc() takes six arguments specifying, position, size, and rotation. We’ve looked at position and size throughout the chapter, but rotation is a new concept. The last two arguments in the arc() call specify a starting and ending angle for the arc, and these values need to be specified in radians (as opposed to degrees).

You’ll see that the first two arguments refer to the x and y position of the rectangle. The rest of the primitive calls should be self-explanatory, referring to the sketch window’s underlying coordinate system. However, the ellipse() command introduces one additional complexity that needs clarification. To illustrate the issue, change the first rect() call in the Simple House example from rect(50, 250, 300, 300) to ellipse(50, 250, 300, 300). Figure 2-9 shows the result. So what happened? 45 Chapter 2 Figure 2-9.
