Question by aleem.razzaq09 · Dec 18, 2013 at 07:33 AM · 2dflickeringunity4.3

2D object flickers on moving Unity 4.3

Hi, I am working on 2D game in Unity 4.3, I have 2d ball which is throwable using swipe on finger on screen, its movement with collision is very smooth on moving but its texture flickers when its moving. If someone already faced this problem kindly suggest me better way to do this or is this Unity 4.3 bug for 2D objects? Thanks

We had a similar issue that was only showing in Editor mode. Check if it also happens on build as it was gone for us.

I've been working in 3D before, but now started a 2D project. Immediately I recognised that every sprite I use, flicker when the camera moves. This cannot be just occasional. And no difference if its a huge sprite as background (the edges flicker) or smaller objects. I've tested all different settings and sizes for the sprites, nothing helps.

OK, I found the solution in my case: Pixels per unit was set to 100 for every image I use (this seems to be default in my project). When set down to 50, the flickering disappeared.

Select the image and check in the inspector. When texture type is set to "Sprite" there appears a field "Pixels to Units" that can be set.

it probably your texture size. if you are using sprite sheet make sure the max size parameter of the texture is bigger then the actual size or else unity will resize the texture and it will look choppy and flicker.

mor info about his you can find in this tutorial session: http://unity3d.com/learn/tutorials/modules/beginner/live-training-archive/2d-controllers

I changed too much texture and set their size accordingly but still facing same issue. I am facing issue exactly same "http://answers.unity3d.com/questions/159491/why-are-high-speed-moving-object-flickering-for-re.html" but this answer is bit different I don't need to use Trail Render. I also facing issue objects flicker when it get more speed.
