Coding Your Backdrop to Change

Coding Your Backdrop to Change

1.  Click and drag a “when green flag clicked” block from the Events category in the Block Palette onto your Code Area. This will tell your code to run when the green flag above the Stage is clicked or when the block itself is clicked in the Code Area.

2.  Click and drag a “switch backdrop to…” block from the Looks category in the Block Palette onto your Code Area. Attach this block to the “when green flag clicked” block.

3.  Use the drop-down menu to select which backdrop you want your game/story to begin with every time.

4. Click and drag a “wait 1 seconds” block from the Control category in the Block Palette onto your Code Area. Attach this block to the “switch backdrop to…” block.

You can change the number inside the white bubble by clicking on it and typing the number of seconds you wish inside. For this game/story, I have set the seconds to three because I want the Stars backdrop to show for three seconds before it switches to the next backdrop I select.

5.  Click and drag a “switch backdrop to…” block from the Looks category in the Block Palette onto your Code Area. Attach this block to the “when green flag clicked” block.

6.  Use the drop-down menu to select which backdrop you want your code to switch to after the first backdrop and wait block. For this game/story I selected the Moon backdrop to be the second backdrop in this code.

7. Test your code! Click on the green flag at the top of your Stage or click on the green flag block in your Code Area.

Can you use the sprite and two backdrops to retell a story or event that has happened? As an example, for this episode I might tell a story about the first time humans touched down on the moon! I could provide facts by coding the rocketship to talk or I could add a second sprite that uses either the record voice option or speech bubble option to tell us all about the first landing!
