Transcript

You can create text that flashes like you see here by continuously changing the color.

First, you need a sprite with text.

Note that if you make the sprite black, the change color by block won't work.

In order to have the text flash different colors, make your words any color other than black.

Now you can use the change color by block to change the color of the text.

To make the words look like they are actually flashing, create code that makes them change color and possibly wait in between color shifts.

You know how to do this.

Now it's your turn.

Add a sprite with words, and place a loop around the change color by block to make it flash.
