TL;DR makes sprite movement more smooth without really affecting project load time or size Toggle "enable fix?" on and off to see the difference. This uses 4 different costumes offset by different amounts to simulate moving the sprite in half a pixel increments, compared to the 1 pixel increment you are normally limited to (you can set a sprite's position to a fractional value but it is rounded before rendering it seems) it uses rotationCenterX/Y in the costume definitions in the JSON to offset each costume so that the actual image file, and therefor md5 hash stays the same which makes the project load faster as it will effectively only load the image once for the 4 copies. If you use more costumes you could make it even smoother. useful for parallax effects or anything where you need to move a sprite slowly. No point really if you are stamping sprites, although it actually make it *slightly* smoother due to antialiasing. 3 proper projects almost done i promise, just waiting for trending to start working again
