Module 13: Creating Animation in Alice3

Animation is created in Alice by moving objects a little bit at a time using several different control structures.

Goals:

• Learn use the control structure doInOrder;
• Learn use the control structure doTogether;
• Learn use the control structure count (a loop);
• Learn use the control structure while (a loop);
• Learn how to combine these control structures to create 3D animation;
• Learn how to create and edit markers;
• Use markers in the animation code;
• Use subparts in the animation code.

Objectives:

• Utilize control structures in your code;
• Determine which control structures to use for more natural movements;
• Implement loop control structures count and while to wave, clap, shake the head, and stomp the feet!;
• Use markers to move an object to a set position.;
• Edit object markers: add, delete, re-rename, and change the color;
• Create an animation that uses several subparts, such as walking.;

Please study the material at each of the links below.

1. Control Structures: Control structures control the order in which statements are executed.
2. Using a count loop to count to 3.: Use count control structure to count to 3.
3. Using a count loop to shake head no.: Use count control structure to shake head no 3 times
4. Using a count loop to wave: Use count control structure to wave 3 times
5. While Loop: A while block is a control structure that loops (repeats) while a condition if true. The statement while(count<5) will cause the block to execute until count is 5 or more. The statement while(True) will create an endless or infinite loop.
6. 3 Guys take turns counting: Using a while loop to count using counter=counter+1
7. Count down and blast off!: Counting down with a while loop: 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 blast off!
8. Scope of variables: It's important where you declare variables.
9. Yeti circles around baby penguin: Uses an endless while loop to circle continuously.
10. Fish swims back and forth: It's important to start and end in the same position.
11. Moose and skunk move between marked locations: Markers let objects move to a marked position.
12. Pixie moves between marked locations: Pixie moves between several markers.
13. Editing markers: Edit object markers: add, delete, re-rename, and change the color
14. A Walking algorithm: Get into position, take three steps, return to starting position.
15. Self Study Questions: What have you learned?
16. Active Learning: Animation: Show what have you learned
17. Discussion questions: What do you think?
