Error building Player because scripts had compiler errors

There is the code

The first line of code says that the script needs UnityEditor code. Which makes it an Editor script. Which means it needs to be stored in a folder called Editor.

Russian translate: Закиньте скрипт UnityCar.cs из папки UnityCarScripts в папку Editor и радуйтесь жизни.
