class setters setting member variable

Projects Programming

Hi Im new to making classes, so far everything has gone well, however I want to make a list of objects, and set the private variables of the objects with methods - setters... however arduino tells me that the member variable is not declared within this scope. I am able to set the variables from the constructor, so I just tried to do it the same way from a method

void setName(String name)
{
	_name = name;
}

doing it from the constructor works:

MyClass::MyClass(int value, String name, String description)
{
  _value = value;
  _name = name;
  _description = description;
}

whats wrong?

void setName(String name)
{
	_name = name;
}

Perhaps that fact that you left the MyClass:: part of the front of the function name is a problem.
