Object and Goods are abstract.

When I derive a class called TruckArrive from it, the titled error occurs.

Please help

Well, you haven't included the code actually causing the error, but it seems you try to derive from the class Activity when the type is not visible and complete. Either you forgot to #include the header where Activity is defined or cyclical dependencies prevent the definition from being known at the point in question.

It is hard to understand your current code as there is an awful lot of it. You probably have a circular header dependency. Check out this article for an overview of how to structure your code.

 

I'd also advise you to consider splitting your code into more headers, and placing more of the implementation in source files.

I believe your onUpdate in TruckArrive needs to be Virtual:

 

virtual bool OnUpdate(float seconds);

No, that is not the problem. If a function is virtual in a base class, none of the implementations in subclasses need to mark themselves virtual. In C++11 it would be a good idea to use the 'override' keyword though.
lucky6969b's problem is just simple inclusion chaos. He needs a better plan on which class needs access to what, he needs to stick to the "one header, one class"-rule, he needs to use more implementation files instead of just writing almost everything in the header, he needs to make better use of forward declarations.

Objects.h includes Idle.h which includes Activity.h which includes Objects.h. This kind of circular dependency is an excellent indication that you need to refactor.
