I am working on a little game and I had a question about screen resolutions.
I can make the display 800 by 600 for example, but the image is stretched if I make a resolution which is bigger then the planned images or, if smaller, it only shows parts of images.
How do "real" games make it so that when you change resolution it affects more the clarity and the amount of pixels then the size of the screen itself? Is there a place to study this subject, some sort of link any of you could offer or some advice on how to have the same effect games have? Is there a certain suggested resolution?
For me basically in allegro resolution becomes a question of size, while in image editors, it is more about pixels per inch, I just want to understand how to apply pixels per inch to my games not just size.
I hope I was explicit enough to receive an answer, thank you for your time.
