7. Wrap-up: Movie Sound Effects and Music Composition
Today, you use an if, then blockto tell the computer what sound to playeach time your projectile spritechange costumes.
If, then statements are an important conceptthat computer scientists use all the time.
Computers can not think or make decisions on their own.
They make decisions based on the code that was written.
If, then statements are one way to tellthe computer to make a decision.
If, then blocks, like thisare also called conditionals.
Because they run in code when a certain condition is met,and they do not run the codeif that same condition is not met.
This concept is used in all types of computer sciencethat you will encounter in the future.
In high school or college computer science classes,in multiple computer science languages,and in the keyboarding and spreadsheet classthat you'll take in high school,you will be a step aheadbecause you will have successfullyused conditionals or if, then blocks.
Next time is your last session of CS First.
But that doesn't mean that your experiencewith computer science has to end.
Remember, you can access Scratchfrom any computer with an internet connectionand you can always return to this CS First websiteto watch more screen casts,build more add-ons to your projectsor even do another club theme like gameson your own.
Computer science is all about creating.
Access to Scratch.
The knowledge that you learn hereand the courage to just keep tryingwill enable you to build anything you want.
In the next CS First club,you will build a thank you project.
