Can someone please refer me to a tutorial or better information that is required to be able to do these tasks? I do find the answers in the help section but still very confused how it works and not sure what part I'm misunderstanding. I see that I am not the only one struggling with this topic. So if anyone in the meantime found better information in regards to this topic of Abstract classes and how to implement them I would very much appreciate it if you could share these with me!
