Activity 5: Learning about Variables[ edit ] Opening up your own Ice Skater example world again: If you haven't already done so, add an event so that when the space bar is pressed your skater jumps. Test your program to make sure that this works. We're going to get our ice skater to remember how many times she's jumped during her performance!
But to do this, we'll first need to create a variable. Just think of a variable as a container where you can store things. Click on the Iceskater object in the object browser and select the Properties tab of the IceSkaters details.
Click on the Create New Variable button. Give your variable the name howmanyjumps. By creating this variable for our IceSkater, we can get her to remember how many jumps she's done. Set the type of the variable to Number and set it's initial value to 0 as she hasn't jumped yet!
Next we need to make sure that whenever our Ice Skater jumps, she adds 1 to our variable howmanyjumps: Click on the Methods tab of the IceSkaters details. Click on the Edit button next to the Jump method, as we want to change what happens whenever she jumps You'll then see a lot of code that's the code to make her jump.
If it worries you, click on the '-' next to "Do Together" at the top to minimize all the code. Click back on the Properties tab of the IceSkater details and drag your howmanyjumps variable over to the end of the Jump code it should be just after the last "IceSkater Set Pose" command.
When you drop your variable their, you'll be able to tell Alice what you want to do with it. Choose the option to increment your variable by 1. Try running your world again That's right, it doesn't seem any different yet! Even though our new bit of code is working, we haven't done anything to help us see what's going on!
To do so, we'll need to use an if statement! We're going to modify our IceSkaters Jump method so that if she's jumped twice already, the next time we press the space bar she'll just say "I'm too tired to jump anymore! When you let go of the mouse button, you will be asked to choose the condition for your If statement Now, we want to do something special when our IceSkater has jumped twice, ie.
To make this happen: Look at your Iceskaters Properties, and drag your howmanyjumps variable into your if statement where it currently says "true". When you drop your variable in the right spot, you will be asked what you want to set as the condition. We want to say something like "If howmanyjumps is equal to 2". Drag this method and drop it onto the first "Do Nothing" of your If Statement. You'll be prompted as to what you want to say, choose Other and set the text to "I'm too tired to jump any more.
Now test your program! You should find that your IceSkater will jump twice, but after that will tell you she's too tired.
Practice: To practice creating variables and using IF statements, we're going to modify our program so that our IceSkater gets dizzy if she spins too much! Here's some tips to get started: Add a new event so that when the 'S' key is pressed, your skater spins and test to make sure it works. Create a new variable for your IceSkater called howmanyspins set to 0 initially. Edit your Iceskaters Spin method so that after all the other code, your new variable is incremented by 1.
Add an IF statement to your Spin method so that if your IceSkater has already done two spins she says "I'm feeling dizzy. Test to make sure it works and get someone else to take a look at your work! A design project[ edit ] Now the fun begins Let your imagination run wild and create your own interactive world!The message must include the result of the calculation performed in Step 7. Display a message on the screen: How much do you get paid per hour?
Multiply the number of hours worked by the hourly pay rate and store the result in memory. The dot separates two pieces of information. Writing a recursive mathematical function. In this area of the screen you see a tile that reads as follows: The authors make extensive use of program visualization to establish an easy, intuitive relationship between program constructs and the 3D graphics animation action in Alice.
