On your own:
1.Enter a TextWindow.Write statement that displays the message “Gallons: ”
2.Enter a TextWindow.ReadNumber statement that assigns the user’s input to the gallons variable
Arithmetic operations
+ addition (also can be used for concatenation)
– subtraction* multiplication/ division

1. Create a 10 line program using the following commands. Keep in mind that the default height and width of the GraphicsWindow is 442 and 624 pixels, respectively.
2. Save and then run.
Turtle.Speed = number from 1 through 10Turtle.Move(number of pixels)Turtle.MoveTo(x, y) Turtle.TurnLeft()Turtle.TurnRight()
1. Close the MyFirstTurtle program.2. Open the Hi.sb file contained in the
Class folder.3. Run the program.
1. ' Lines 2 through 8 will center the GraphicsWindow2. GraphicsWindow.Hide()3. gwH = 4004. gwW = 2255. GraphicsWindow.Left = (Desktop.Width - gwW) / 26. GraphicsWindow.Top = (Desktop.Height - gwH) / 27. GraphicsWindow.Height = gwH8. GraphicsWindow.Width = gwW
10. ' Line 11 displays text on the title bar11. GraphicsWindow.Title = "Hi"
13. ' Line 14 shows the GraphicsWindow14. GraphicsWindow.Show()
16. ' Line 17 sets the Turtle's speed17. Turtle.Speed= 9
19. ' position turtle and draw left vertical line in H20. Turtle.X = 5021. Turtle.Y = 35022. Turtle.Move(250)
24. ' reposition turtle and draw right vertical line in H
25. Turtle.PenUp()26. Turtle.X = 10027. Turtle.Angle = 18028. Turtle.PenDown()29. Turtle.Move(250)
31. ' reposition turtle and draw horizontal line in H
32. Turtle.PenUp()33. Turtle.Y = 20034. Turtle.TurnRight()35. Turtle.PenDown()36. Turtle.Move(50)
38. ' reposition turtle and draw vertical line in i
39. <lift the pen>40. <set the turtle’s X property to 150>41. <set the turtle’s Y property to 350>42. <turn the turtle to the right>43. <put the pen down>44. <move the turtle appropriately>
38. ' reposition turtle and draw vertical line in i
39. Turtle.PenUp()40. Turtle.X = 15041. Turtle.Y = 35042. Turtle.TurnRight()43. Turtle.PenDown()44. Turtle.Move(200)
Answer
Drawing Shapes
46. ' draw circle above vertical line in i47. <use the GraphicsWindow’s DrawEllipse method (Hint: use 145 and 100 for X and Y, and use 10 for the width and height>
Drawing Shapes
46. ' draw circle above vertical line in i47. GraphicsWindow.DrawEllipse(145, 100, 10, 10)
Answer
1. Close the Hi program.2. Open the PicViewer.sb file
contained in the Class folder.3. Run the program to see the effect
of the existing code.
13. ' Lines 14 through 16 load the images and assign names to each14. imgBirds = ImageList.LoadImage(Program.Directory + "\birds.jpg")15. imgCat = ImageList.LoadImage(Program.Directory + "\cat.jpg")16. imgTheEnd = ImageList.LoadImage(Program.Directory + "\TheEnd.jpg")
18. ' Lines 20 through 22 make each loaded image a Shape object that can19. ' be moved, animated, shown, hidden, or rotated20. birds = Shapes.AddImage(imgBirds)21. cat = Shapes.AddImage(imgCat)22. theEnd = Shapes.AddImage(imgTheEnd)
24. ' Lines 25 through 27 position each Shape object at the right edge of the GraphicsWindow25. Shapes.Move(birds, 650, 0)26. Shapes.Move(cat, 650, 0)27. Shapes.Move(theEnd,650, 0)
29. ' Lines 31 through 33 hide each Shape object (this is necessary because the30. ' AddImage method automatically displays them on the GraphicsWindow31. Shapes.HideShape(birds)32. Shapes.HideShape(cat)33. Shapes.HideShape(theEnd)
35. ' Line 36 shows the GraphicsWindow36. GraphicsWindow.Show()
38. ' enter the code to play a wav file named PicViewer.wav
39. <Use the Sound object’s Play method, the Program object’s Directory method, and the concatenation operator to play the "\PicViewer.wav" file.>
38. ' enter the code to play a wav file named PicViewer.wav39. Sound.Play(Program.Directory + "\PicViewer.wav")
Answer
41. ' Lines 42 through 44 show the birds Shape object, animate it, and then delay the program
42. Shapes.ShowShape(birds)43. Shapes.Animate(birds, -500, 0, 6000)44. Program.Delay(4000)
1. Complete Lines 46 through 54.2. Save and then run.3. For an additional challenge,
complete the DIFFERENT VERSION section.
1. Enter the following two lines of code:txtName = Controls.AddTextBox(100, 50)btnHello = Controls.AddButton("Hello", 100, 100)
2. Save and then run.
1. Enter Controls followed by a period.2. Press the down arrow until the ButtonClicked
event is selected.
Now we need to create the OnButtonClick event procedure. Enter the following lines of code:
5. Sub OnButtonClick6. myName = Controls.GetTextBoxText(txtName)7. GraphicsWindow.ShowMessage(myName, "Name Entry")8. EndSub
Take your pick:
1.Create the Space Invaders game using the handout provided to you.2.Look in the EXE folder on your flash drive for a program you might like to create. Then, locate the partially completed .sb file on your flash drive. The FolderContents.doc file on your flash drive provides some additional information about the program.3.Create your own Small Basic program.4.Check out the Coin Toss.sb program in the Coin Toss folder.5.Import one or more of the following programs/games:
XHX455 (Click Shapes) KXM316-0 (Calculator)CBX615 (Flower) LWL206-3 (Music Notes)MDJ923 (Paddle Game) PMT149 (Bouncing Balls)
