In this add-on, you will program letters to flash across the screen, and spell out your cause.

To start, click choose sprite from library, then click letters.

There are a few different styles of letters.

Choose a style you like, and find the first letter of the name of your cause.

To add the rest of the letters of your cause, select the costumes tab, click choose costume from library, and add the next letter.

Repeat this process until the entire word is spelled out.

Add the letters to a single sprite.

Each letter will be its own costume within a sprite.

Take a look at the example project.

When the play button is pressed, the letters flash across a multi-colored backdrop.

Then, the letters disappear and the backdrop switches.

At the same time, the rest of the sprites appear on the screen.

To make the letters flash across the screen when the play button is pressed, select the letter sprite, and add a when I receive play block.

Add a next costume block to make the letter on screen change.

To spell out the entire word, add a repeat loop.

Make the number in the repeat loop one less than the number of letters in the word.

Sports is six letters.

The animation will start with the first letter, S, then change costume five times to show the five following letters and spell out the entire word.

Try it out.

Hmmm.

Letters were changing too fast to read the word.

To fix that, add a weight block after the next costume block.

Adjust the time in the weight block until the name looks readable.

To make the letter sprite start on the first letter of the word when the play button is pressed, add a set costume block above the epeat block.

Select the first letter of the word in the drop-down menu.

Add a weight block under this block too.

To make the letter sprite disappear after it spells out the name of your cause, add a hide block at the bottom of the code stack.

Make the letter sprite re-appear when the play button is clicked, by adding a show block under the when I receive play block.

Run your code again.

This looks pretty good, but the letters look a little small.

Add a set size block under the when I receive block, and set the size to something greater than 100%.

This example uses 200%.

Run your code.

This is a pretty cool effect.

You can stop here and move onto your next add-on.

Or if you'd like, make the backdrop change and the other sprites disappear when the letters flash on the screen.

Then, program the sprites to re-appear after the word is spelled out.

To do this, select the stage and add a when I receive block.

Select the play message from the drop-down menu.

Under this, add a switch backdrop block, and select beach ball from the drop-down menu.

To make the other sprites hide when the animation starts, add a hide block under the when I receive play block for each sprite.

Make the sprites re-appear after the letters flash on the screen, by selecting the letter sprite and adding a broadcast block to the bottom of the code stack.

Click the drop-down menu, select new message, and call the message something like, show sprites.

For each sprite, add a when I receive block and select show sprites from the drop-down menu.

Under this, add a show block.

Select the spokesperson sprite.

This sprite delivers the opening message when it receives the play message.

To make the sprite wait to say the message until after the letters have flashed on the screen, click and drag the say blocks from the when I receive play block to the when I receive show sprites block and place them under the show block.

Finally, to change the backdrop back to the one you selected after the letters stopped changing, click the stage, and add a when I receive block.

Select the message you just created and add a switch backdrop block.

Select your original backdrop from the drop-down menu.

Click the play button to try out your code.

Awesome, what a great way to start your viral video.

Now it's your turn.

Program the letter sprite to flash across the screen.

Then, hide the other sprites when the letter sprite is shown.

Finally, show the other sprites after the letter sprite has finished spelling out the name of your cause.
