In this video, you will paint your graffiti on different backgrounds just like a real graffiti artist.

When you press certain keys the backdrop will switch.

First, add a few new backgrounds.

Click on the stage, then choose a few new backgrounds from the backgrounds menu.

Pick several and be creative.

It could be fun to spray paint in space for example.

Next, go to the scripts area then add some key press events.

This example uses the number keys for key press events.

For example, when the two key is pressed the background switches to the chalkboard.

For each background, add a key press event and a switchback drop to block.

You should have the same number of block stacks as you do backdrops.


Make sure to test each block stack to see that it works how you expect.

Also, set to the beginning backdrop by using a when flagged clicked event.

Now, let the users know they can change the background.

Add a talking sprite to let them know about this fun feature.

The sprite will ask the user what background do they want to paint and instruct them how to change the background.

(long pause)

Add the when flag is clicked block to the script area along with some say blocks.

Write directions that tell users how to change the background.

Now it's your turn.

Create several new backdrops.

Add key press events to change the backdrop using the switch backdrop to block.

And finally, add a talking sprite that tells the user how to change the backdrop.
