Unity built-in components are basically not inheritable. Some of the features that are commonly used but are not defined by the existing API can be implemented using the C # Extension class method (note that the extension method does not pass a reference to a value type, so the original object cannot be modified, and passing a large value type can cause performance problems). Here are some of the more pract

It contains the class MyPerson. This class stores 3 values of type double, an
