Скачать или смотреть Unity 5 Pixel Perfect Sprites

You create a sprite in photoshop and bring it in to Unity 5. Ever wondered how to get it to appear pixel perfect, in 3d mode, so that it is pixel for pixel the same as it is in photoshop? Well, this video shows you how and this process works with either Orthographic or Perspective cameras.

Often in my games I will want to have some element be pixel perfect on the screen. Even if I'm in a 3d game I might either have a background plate or a HUD (heads up display) icon or UI element that I want to be re-sized to be pixel perfect. And I don't want to use the GUI if I can avoid it.

It isn't difficult to do with an orthographic camera. You can use the pixels per unit setting on the sprite. But for a perspective camera it's a little more tricky.

This video shows how to achieve that within Unity. It's a couple of very simple scripts that you can use to set the z depth of a sprite to be pixel for pixel the same as it is in Photoshop.

NOTE: my formula for the depthZ in the script had a mistake. It should have been:

focusZ = Camera.main.transform.position.z + unityDepth;

It was working in the video because the camera had a position of 0. The above formula works for all camera positions, again as long as the camera is pointing straight ahead.
