SCRATCH

APP – HELLO GOODBYE DING DONG

DESCRIPTION

First off, this is the best application name in the history of application names. Period.

For this application, you make your sprite do the following in order:

· Display the text bubble “hello”

· Display the text bubble “goodbye”

· Play a sound (doorbell sound or any other)

STEPS

Since this is likely one of your first Scratch applications, we will go over the steps in details.

STEP 0 – GETTING STARTED: INTERFACE

• If you are just starting in Scratch, make sure to look at the User Interface description in the FAQ section of this site.

STEP 1 – THE GREEN FLAG EVENT

• To make code run when the program is started (green flag is clicked), then we need to add the following event to your code by dragging it onto the right section.
  
  

Now, any code that we place under this block will execute when we hit the green flag.

STEP 2 – SAY HELLO

• In the Looks section of blocks, you will find the say (hello) for (2) seconds. Drag it under the existing block and change the message to say “Hello” or “Bonjour”.

STEP 3 – RUN YOUR PROGRAM

• Click on the green flag in the Application section. You should see a text bubble appear beside your sprite with your message. It should disappear about 2 seconds.

STEP 4 – RUN IT AGAIN

• Click on the green flag again to see your program run again.

• Note that you can also simply double click on your code block to run that block and see its effects.

STEP 5 – ADD ANOTHER MESSAGE

• Make your character say “Goodbye” by adding another block at the bottom of your code. If you are unsure, it should look like this:

STEP 6 – TEST YOUR PROGRAM

• Test your program. You should see your sprite show a bubble with your first message and then again with your second message.

• Notice that the order of your code statements matter. If you switch the order if your two purple blocks, it will display the messages in the opposite order. Try it and switch them back.

STEP 7 – CHOOSE A SOUND

• We want to play the doorbell sound (or any other you want).
• Click on the Sounds tab.
• Near the bottom left, click on the Choose a Sound button.
• Find the doorbell sound (or whichever one you want) and click on it.
• The sound should now be listed on the left.
• Click back on the Code tab.
• Under Sound, drag the play sound (Doorbell) until done statement to the bottom of your code block.

STEP 8 – TEST YOUR PROGRAM

• Test your program. You should see your two bubble messages and then hear your sound.

STEP 9 – SAVE YOUR PROGRAM

• Use File > Save to your computer to save your program into your Downloads folder. You can then copy that file into another folder and rename it if you want to have it for later.
