How to check if a condition is not met in Scratch? Preview

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.

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".
