In this video you'll programthe backdrop to change three timesto showcase three projects you'd liketo show off and describe.
After each change the sprite will say somethingabout the project.
To start, pick three projects to describe.
Select the stage and click the Backdrops tab.
This starter project includes backdropsfor all seven projects that you created in this club.
You might choose projectsbecause they were fun or challengingor maybe just because something funny happenedwhile you were working on them.
Once you choose the three backdrops for your project,program them to change.
Select the Looks menu.
Three blocks here can change the backdrop.
Switch Backdrop To, Switch Backdrop To And Wait,and Next Backdrop.
Next Backdrop switches to the next backdrop in a listso it won't work for this project.
Switch Backdrop To and Switch Backdrop To And Waitwork similarly but you compare the Wait versionof this block with a When Backdrop Switches To eventto wait until all the code under the event has runbefore moving onto the next piece of code.
That sounds like it'll work well for this project.
Drag out three Switch Backdrop To And Wait blocksand change the values to the namesof the projects you want to describe.
If you don't remember the name of a project,click the Backdrops tab to see the name of each.
Then add a When Flag Clicked event and try it out.
Whoa, those changed so fast.
You can hardly see 'em.
That's because you haven't programmed anythingto happen on each backdrop.
To fix this, switch over to the cat spriteand program it to say something about each backdrop.
Click Events and drag out threeWhen Backdrop Switches To blocks.
Again, you'll need to change the values of these blocksto the three backdrops you've selectedthen click Looks and drag a Save For Two Seconds blockunder each event.
Try it out.
Scratch highlights code as it runsso look at the code to see when each block stack runs.
You'll see that first this code stack runs,the backdrop changes and the cat says, "Hello."
Then the backdrop changes, this code stack runs,and the cat says, "Hello."
And finally the last backdrop change occursand the cat gives one more hello.
Now that you've programmed the cat to say helloat each backdrop, program it to say whatever you'd likeabout each project.
Add as many Say blocks as you'd liketo describe each event.
Remember, in this time lapse story,you're sharing your experiencesin this club with other people.
There's a list of possible things to write aboutnext to this video.
Check out this example that uses a few linesto talk about each project,describes a silly thing that happened while workingon the project, and thanks friends.
Now it's your turn.
Select the stage and use three Switch Backdrop To And Waitblocks to change backdrops when the flag is clicked.
Select the sprit and use three When Backdrop Switches Toevents and Say blocks to describe each backdrop.
Choose 3 projects to describe.
Make the backdrops change when the program starts.
Program a sprite to say something about each project.
