HI everyone. i want to make hand drawn art for my game. what is the best size for images to not harm memory performence of the game?
bat not harm the quallity of the images (sorry for the bad english )
It depends in your layout size and window size in which size of your graphics will match. But it really depends in the number of instances you are gonna create. For example...
If I were to make a HD Game of 1280x720 px(Windows Size) in landscape orientation and every Tile is sized 128x128px. It will be okay if I create a layout that is small like (3000, 3000) or (6000, 6000) max and object count is limited to 200 to 100 or below (mostly tiled backgrounds) but If I were to use Tilemaps then it will be another story(It will be a lot lesser). I know that by looks of it, it looks so many but if you include everything that your game needs for an Open World Platformer game then it is already enough and can be optimized. I know cause I tested it in my phones, if they are WebGl supported then it will surely run 50 to 60fps Crosswalk.
My point is, that if you have bigger images then limit the object count but if you have smaller images you can have a little bit more instances.
Mobile Game Screen Ration 16:9 HD - Windows size (1280, 720) and make tiles(repeatable images) according to the size you want to be seen in your game.
