Appendix C has more information on changing the settings for Alice’s screen capture function. 4. The Stop button stops the world that is currently playing and returns you to the standard Alice interface. Once the Stop button is pressed, you will need to click the standard interface’s Play button to replay the world. Try this now. After you have finished experimenting, click the Stop button one last time to return to the standard Alice Interface. Exiting Alice Alice is a graphics intensive program that can use a lot of a computer’s memory, so you should exit the Alice program when it is not in use. Now that you are finished with this tutorial, you should exit the Alice program. ~~~ Steps to Perform ~~~ To exit Alice: 1. Click File on the menu bar, and then click Exit . 2. If you have made any changes to the current world since it was last changed, a Save World? dialog box will appear , asking you if you want to save the world first. If this happens when you attempt to exit Alice after viewing the lakeskater world, then click no, so that you do not change the saved example world. NOTE: While you are viewing or editing an Alice world a dialog box will appear every 15 minutes warning you that you have not saved your Alice world. If this happens while you are playing an Alice world, such as in tutorial 1B, then it’s probably safe to ignore the warning. If it happens while you are creating or editing your own Alice world, then it’s a darn good idea to save your world .

Alice – Chapter 1 DRAFT June 10, 2013 pg. 20 of 38 Tutorial 1 C — Creating Your First Alice World In this tutorial, you will create, play, and save a new Alice world. You should have finished tutorials 1A and 1B above before starting. You will create an Alice world, in which a bunny will move from the right side of the screen to the center, turn to face the camera, and then say “Hello, world!”. This is an Alice equivalent of the “Hello, word!” program that students traditionally write as their first program in a new programming language. The tutorial begins with the Alice software closed. If you have an Alice world open, then exit Alice before continuing. ~~~~ Steps to Perform ~~~ To start the new world: 1. Start the Alice software. 2. Click File , and then click New World . You should now see the Templates tab of the Welcome to Alice! dialog box, as shown in figure 1-5. 3. Thumbnail sketches for six new world templates are now available – dirt, grass, sand, snow, space, and water. The templates appear to be very simple with a texture for the ground and a Figure 1-5.

There is actually a great deal of computer programming behind a new Alice world, with a camera, ambient light, and other elements already in place. Click the grass thumbnail, and then click the Open button.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
