When we wish for a sprite to appear or disappear on the screen, there are two ways in which we can achieve this. One of them would be to create the sprite when we wish to see it and destroy it when we want it to disappear.
Another way to achieve this goal is to make the sprite invisible when you wish for it to disappear and make it visible again when you need it again.
The blocks that make sprites invisible and visible again can be found in the purple block palette:
The "show" block makes the sprite visible and the "hide" block makes it invisible!
Warning: If you create a copy of a sprite that is invisible, that copy will also be invisible.
This Tutorial is used in the following courses and lessons
"Keep 'em clean" is a game that uses the players' real-life movement captured by a camera to control many "people" and push them towards a sink where they wash their hands! In this course, you will learn the basics of programming with Scratch, as well as using the "Video Sensing" extension to receive movement from the camera!
In this lesson we will solve a problem we discovered in the previous one- the original sprite does not move in the same way as the clones!
How do you think we can solve this problem?
Today you will find out how to make the program have one dirty sprite and ten clean ones, and for all of them to move in the same manner!
