Some conditions are easier to describe in Scratch than others. We can check with a single block if a sprite is touching a color or if it is touching the mouse.
For more complex conditions, such as whether it is NOT touching a color or whether it is NOT touching the mouse, we need more blocks.
There is a block in the green block palette that allows us to describe such conditions:
In this block, you can place other conditions:
Conditions placed inside of this block are changed so that they return "True" if the condition is NOT met and "False" if the condition is met. If this block has a check "is the sprite touching something yellow", then the check would be changed to "is the sprite NOT touching something yellow".
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 make one of the most important things for a game - the Victory screen!
How should it look? When does the player win in the game?
The look of the victory screen will be up to you. The goal of the game is for all hands to be clean and only then would the game register as a win!
