Spine2d pixel art size unity
In the middle, I scaled up Mario and the level to twice the resolution of the background, and the mole to triple the resolution.

In the example on the left, I put together some sprites from Super Mario World, all at the same scale, and it looks great. When you use pixel art at different scales, it can look like assets have been cobbled together from different games, instead having a unified aesthetic. This "rule" comes down to stylistic consistency. This is another case where there's no easy universal fix, and you'll have to apply some judgment and artistry to keep your game looking sharp.

The solution is to use a combination of padding/cropping or alternate asset sets to get back to a consistent, whole number ratio of screen pixels to texels for each display resolution you want to support. Rounding already happens as part of the nearest neighbour filtering - the problem is that some screen pixels round to the same source texel (duplicating it), while others don't, leading to an uneven result. You'll often see people suggest rounding camera or object positions to integer pixel coordinates, but that doesn't really fix the problem. In motion they tend to make sprites ripple and shimmer distractingly, without an obvious cause:

Imagine your game is in NES resolution (256 x 240), and you want to display it on a 1080p screen.ġ080 ÷ 240 = 4.5, so some of the source pixels or "texels" in your scene get blown up to 5 screen pixels across, while others are only 4, creating distortions like we saw above. For whole-number scales, you can use specially-designed pixel art upscaling algorithms - a wide variety are available in tools like ImageResizer - to get a less blocky starting point than Nearest Neighbour, but it still takes an artist's eye and some elbow grease to get a high-quality result.Īside: fractional scales can also crop up at runtime. Unfortunately there aren't a lot of great shortcuts for this. (Though I'm not a great pixel artist myself, so it could still be better ?) Now it looks more like something an artist would make, and stylistically consistent with other art in the game. If we really need the sprite to be 150% bigger (say, to make the gameplay feel right, or to support alternate display resolutions), then we can repaint the problem areas like the example on the right. it doesn't look like something a pixel artist would draw on purpose. One eye is bigger than the other, some outlines are thick while others stay thin, and the rounded spots look blocky. In the middle we've scaled up the mushroom sprite by 150% using Nearest Neighbour filtering, and the result looks wonky and haphazard.

Unfortunately, image editing software and GPU texture filtering aren't very choosy about where they duplicate or skip pixels - they just follow basic rounding rules - which can make the result look distorted and uneven.Ĭheck out the example below.

This has another wrinkle: since the number of pixels after scaling isn't a whole-number multiple of the number of source pixels, some source pixels will get duplicated more than others (if scaling up) or skipped entirely (if scaling down). So instead we'll usually use "Nearest Neighbour" filtering (also called Point filtering) so that each pixel after scaling takes its colour from exactly one pixel in the original sprite. But on big chunky pixel art this quickly destroys the crisp look. We can't really have "half a pixel."įor other kinds of art we can often get away with blending adjacent source pixels where the pixel should be "half coloured," and at high resolutions the artifacts usually aren't noticeable. 1.5x) because pixels are discrete by nature.

We run into trouble though when scaling pixel art by a fractional amounts (eg. nx is simple - each pixel just becomes an nx n square of pixels, and the look of the original sprite is perfectly preserved (including all the sharp lines, corners, and staircase zig-zags).
