What I trying to ask and what you have answered. Do I use the right classes or too much classes there. So if my idea of using these classes are right. What you wrote is what I had in mind with 2Â classes but the idea of a lastFrame could also be working. and I also agree with you about the responsibilities of the classes. Roelof

Hi Roelof, I always wonder, what kind of answer you expect from your prior statement. To your question: "Can this plan be working or is there improvements to this plan." I can have this answer: Yes, it could be both: working or fail, but you don't know before you try. This exercise is a bit tricky: 1) I can recommend to use also LastFrame class, which has specific handling of bonuses in last round of game (subclass of Frame). Bowling game can be then initialized with array 9 Frame instances and last instance could be LastFrame. I used specific test methods on frame classes like: #isFrameComplete, #isLastFrame, #isSpare, #isStrike, #isOpen. 2) Beware that Bowling game should know only necessary things and delegate responsibility to its frames. Game itself knows that only if all frames are completed, game ends. 3) Total score is sum of all throws+bonuses of individual frames, etc. Does it help to start with exercise?

Re: where are the nills come from and how do I get rid of them

by jtuchel＠objektfabrik.de

Hi Roelof, one thing I sometimes dislike about the way you try to find your way is that you almost never answer to anything people ask or tell you. This is not only not helpful, but also off-putting. I was asking you a simple question: did you get any errors due to nils or are you just wondering why nils show up in an Inspector? And I wrote that if this is only about what you see in an inspector, you shouldn't worry. Your answer: "I will try to make the tests green". Red/Green/Yellow tests have never been a topic in this thread. You had just written "I see nils". Where? When? What did you expect? Sorry, but that kind of answer just gives me the feeling you are either not listening or not giving sh*t abot my time. If you aren't listening, please tell me and if possible give me a reason for it. I will stop answering your questions and not bother you any more. If you find my answer isn't helpful, please ask back or tell me what I am misunderstanding. Maybe we just need to talk about a tiny detail that hasn't been mentioned before. Or tell me what else is wrong with my advice in your opinion. Don't get me wrong: I also tend to ask way too unspecific questions. And I often really feel bad about it. Most of the time it is just my helplessness that keeps me from mentioning all the details that are required to give a decent answer. Asking intelligent questions is hard, at least in my opinion. It is especially hard if the room around you is filled with way more question marks than orientation points. But that shouldn't keep you from helping people who try to help you and ask back for more details. Sometimes people ask in order to get info on what you really are asking about. It may or may not help in finding out if I (or anybody else) can help. And it may help the right answer to your question.
