so, as i am creating this post, I realized that I made an error. Luckily, it's very early in my game's development. I was creating my pixel art 60 x 60 thinking all is good because 60 goes into 1920 and 1080 evenly but, I don't believe this is how pixels/resolutions/aspect ratios (work or do they)? however, I'll still be asking the original questions just in case i may be wrong. I have read a few yo yo games forums, videos and such and still have that feeling of "I need absolute and confident answers from someone so, I know what I am doing is 100% right and that I won't regret my current actions in the future.". Question 1: Would it be better if I start fresh with 240 x 135 for my pixel art and not go smaller? Question 2: I hear a lot of "use the smallest possible resolution for .....". does that mean that my smallest resolution that I use for my pixel art be 240 x 135? is going smallest to biggest a good design and why? Question 3: would everything be okay if I go 60 x 60 since the game will be up scaling the pixels and that it goes into 1920 x 1080 evenly? I don't think it will work since 60 doesn't evenly go into 270 or 135. if it up scales it'll lose its pixel perfect once it reaches 270 x 135 and larger? Question 4: What is the smallest resolution that I can use before I step out of the "pixel perfect" boundaries? I would assume its 240 x 135 but, can I go lower such as 60 x 60?smaller? Question 5: When one refers to their game/monitor "native resolution"(ex: 1920 x 1080), would that be referring to the default resolution of the said game/monitor at which is was originally created at? ex: if I made my game at 270 x 135 and one is playing it at 1920 x 1080 then they would say the native resolution would be 270 x 135 and not 1920 x 1080? 1920 x 1080 | my monitor's native resolution and game's target resolution 960 x 540 | /2 480 x 270 | /2 240 x 135 | /2 this resolution would be the smallest I should go or think of? 120 x 67.5 | pixel perfect can't be done in fractions. 60 x 33.75 | I was using 60 x 60 but, realized that isn't right. 30 x 16.875 | pixel perfect can't be done in fractions 15 x 8.4375 | pixel perfect can't be done in fractions conclusion: I, more or less answered my own question as I was creating this post. However, I would still like feedback from someone who understands this stuff confidently. The last thing I want is having a nuisance of creating an entire game in a bad resolution and forever be stuck that way. I believe I should scrap all of my pixel art and go to a resolution of 240 x 135 because it's better to go small to bigger to biggest. Thank you.
