Hello, I have a problem with getting my image on the screen. Since I only started learning SFML today, I probably just did some dumb mistake due to my lack of knowledge and understanding, but I can't figure out what it is and I'm getting sleepy... If you have some time, please take a look and point it out if you can find it. Thanks in advance!
#Edit: Since I didn't put the more detailed explanation of my problem, I'm doing it now: Ok so, I wanted to put my test image (the one from Engine::LoadImages() - it is in the right folder) on the screen. What I get is some strange assertion error (thus my assumption that I made a mistake in the code) and after I skip the error, I get a black screen (probably meaning, that it's doing the "window clear" stage) That's all I can tell with my tired mind - I hope it helps!
(If this subforum isn't for such requests, then I'm sorry and simply ignore this thread)
