What is the difference between us telling you here what to do or us telling you to go read something you think you fully read but obviously didn't? Almost no difference.
There is a reason we tell you to read those things over and over... it's because the answer is in it, and it isn't that hard to find the answer either, compared to some other documents. If you are unable to read it or fully understand it because maybe English isn't a language you can speak well, then say so and maybe someone can explain it to you in your native language. Otherwise, the only difference between seeing the answer here and seeing it in the tutorial is that we do the searching for you, and that is clearly not the way to learn how to solve problems on your own. If you want to learn how to use SFML, at least learn to solve problems on your own first, it is much easier than learning how to use SFML and it will help you a lot in the future.
Don't get me wrong, even I was a beginner once, and there is nothing wrong with being one. What matters is whether you are willing to invest effort into learning new things. As with all things technical, learning to help yourself is always the first step, and many people seem to forget that or simply don't care. It is those kind of people that I also don't care about because they are just a waste of my time. All forum contributors post in their free time, so it makes sense that we want to maximize the effect of our posts. Even if it hurts in the beginning, it is better in the long run because potentially less questions will be asked since people have learnt to help themselves better.
We all went to school, and as an adult, none of us can truly say it was a waste of time although as children some may have considered it a waste of time not understanding the long term goal.
