# Alice Boolean Logic

Alice Supports Several Boolean Logic types. They exist under the world functions :

# Rock Paper Scissors Part III [Alice 2]

In the Part 2, we ended with a dilemma. If the user wants to play a second game, we need hide the objects that were chosen in the first game!

1. So, at the start of the main while  loop, you should programmatically set the isShowing  of all 6 objects to false.

Note: all commands in alice have a duration.  Since we want all 6 objects to immediately hide, s et the duration to 0 by clicking on more and selection duration as shown below:

So, now you should have a fully functional Rock, Paper, Scissors Game that should work similar to what you can see below  (Still, there are some improvements that could be made ,see the bottom).

However, there are some improvements that we should make.

# Rock Paper Scissors Part II [Alice 2]

Part II

1 Create a variable called userChoice

2. Use the world ask user for  a number function to store the user’s choice into that variable (Note: if the user chooses a number larger than 3 or less than 1 then they entered an invalid number, something to think about

3.   Set the isShowing  property of all 3 objects to be false .  We will set the visibility to true , when the user chooses that object , later on .

Objective; If the user chooses rock, we  need to show a rock; if the user chooses scissors, show a scissors, and the same for paper.

Use if/else and the value of userChoice  and set the isShowing  of either the rock , the paper or the scissors to true

Remember:

1= Rock

2= Paper

3= Scissors

### Run through the program a few times. What should we do next ?

4.

We need to show what the CPU chooses!!

So, now we need to do a few  things:

A) edit our if/else  to consider what the user chose and  what the cpu randomly chose (both/and)

B) add a second rock, paper and scissors object that represents the CPU’s choice

(note: I set the color of the CPU’s objects to red so I can more easily distinguish the cpu’s from the user choice’s objects)

C)  Set isShowing  to false for each of the cpuChoice’s objects

For instance, if the cpu and the user both choose rock, your screen should look something like :

5.   State who won the round or if the round was a draw :

7. The last line of your loop should ask the user if they want to play again.

Try playing the game a few times. You will notice that there is a problem, when you play multiple times

Can you see what is wrong with our current setup? The bug only applies to multiple games. If you play a single game and close Alice, you will not notice the problem.

As you can see above, when you  start  a second game, you can still see the rock and paper that were chosen in the first game.

Can you figure out how to fix  the problem?

Go here to see how to fix it and continue on with the project.

# Rock, Paper Scissor Game

We are going to create a Rock, Paper, Scissors game using Alice loops and if/else ‘s

1. 1.Add a “rock”, “paper” and “scissors” objects to screen and enlarge them all to approximately the same size:
2. Make a Boolean variable called gamePlaying  and set its initial value to true :

3.Add a while loop based on gamePlaying

4. Make a variable called cpuChoice.   cpuChoice  is a number This variable will represent what the computer randomly chooses (rock, paper or scissors)

5. Use the world function that generates a random number so that the random number is an integer between 1 and 3 , inclusive.

Store the return value of that random number generator into cpuChoice  at the beginning of the loop

6. Debugging has many meanings. Experienced developers build debugging and logging into the development of their programs from the start.

• We are going to do that in Alice by “watching” the cpuChoice variable

7. Right click on cpuChoice  and select watch this variable

8 .Now we have the computer randomly choosing either 1,2, or 3 and these numbers will represent rock, paper and scissors respectively

### So, what do you think we should do next?

Overview: Using Python, students will use variables, input, and printing to create a Mad Lib. You will also practice designing a project by planning out your Mad Lib before implementing it. Part of the project is to use your creativity to design your own unique story.

The program will print out the title of the Mad Libs story, as well as a short explanation of game play

The program should then prompt the user to enter in nouns, verbs, adjectives, proper nouns, and adverbs

### Implementation Details

Plan out your story on pencil and paper first, before you start implementing the program.

• Select the missing words
• Determine each words part of speech
• Create introduction
• Create questions
• Divide story into print statements

As mentioned above the program must request words from the user. The following must be included in the program:

• 10 different words inputted
• Variable names should correspond to the part of speech requested and part of the story they belong to (e.g. `noun1``verb2`, etc)
• You may only use 3 print statements to tell your story

# Meaning of “==”

Here’s how you get to “==” in Alice. It’s a world function. (and it must be put into an if test)

# Math Expressions in Alice

Alice Supports many types of Math Operations.

For instance, let’s say that we have the variable someNumber  and it has a value of 2

## What if we want to multiply 2  by  0.5 ?

1. click on the down arrow next to “2” and select “math”

2) select “2*”  which means “2 times ”

3) Select “Other” for the second number “b”

4) The calculator appears so you can  choose 5

5)  Select “5”

6) Viola: You know have a math expression that represents 2 * 5

8) Now let’s make a variable called “divisor” and then divide this expression by that

9) Select the down arrow

10) select as shown:

11) Viola :

# Alice 2 : Asking User for Input

The world object has many, many useful functions including a way to ask the user for information—say  a number, a name or something.

1.  Click on world
2.  click on functions
3. scroll down ot the ask user functions (See Diagram 1 ) and read below for more
