What wont work is what is in my CWarrior class the method special. Any ideas why not? I tried using a pointer but it kept saying must have struct/unioin/type before .setName("BLAH");
Here is my source:
Thanks,
There are a few incorrect things. First, setName() is definitely wrong since you're using char* and not std::string. You have two choices, change char* to std::string or use strncpy(). Second, there is another problem in that very same function. You need to declare fighter as CFighter& or CFighter* because otherwise you will only have copy of the object. If you use the first one you will have nothing to change in your code but the declaration/definition of your function but if you chose the latter one, you will have to change fighter.setName() to fighter->setName() (you should already know this if you're into GDI & game programming...)
*EDIT* You might want to declare CFighter as an abstract class if you plan to make it a base class for multiple other classes. It will allow you to use polymorphism and make things easier...
Ex:I didn't compile that code but you get the idea..
