Question by MrFalseEye · Jul 27, 2015 at 10:38 AM · camera2dorthographicsetting

Orthographic Camera settings for a 2D game

I'm starting out a 2D wrestling game and i need some help. The default resolution of game needs to be 320x240. The background sprite that i would be using is 640x480. The camera would move over the background to give it a hovering look. I want the Camera to cover exactly 320x240 resolution. I tried setting the Camera size to 1.2 and it looks approximate but i wanna be sure that the camera is exactly 320x240. By default all the images are set to 100 Pixels per Unit. Also, i would like to change Filter mode for all images to point mode all together. I know i can set it for an individual image in inspector but i need a way to set it together for all images since i have a lot of them. So my question is,

  • How to set the camera to cover exactly 320x240

  • How to set image properties like Filter mode for all images in the project

Hi, there are lots of tutorial on how to setup a scene with pixel perfect sprites and camera (searching for "pixel perfect" should give you some results)

For the second point: you can modify parameters when selecting multiple textures at the same time in the project window. If your textures are in multiple subfolders, you can apply a filter for name and asset type before multi-selecting. For example: searching for "t:texture green" will show all textures that have "green" in their name. Lastly, scripting can also help set import settings to any/all object, check TextureImporter.

Your orthographic camera size depends on the pixels per unit of your sprites.

Orthographic camera size is equal to 1/2 of the vertical units (meters if you use built in physics) you will see on the screen. Say size 6 means that your screen height will be 12 units.

The formula is: screen resolution / 2*orthographic size = pixels per unit on sprites

Filter depends on your preferences - for low res you probably want "point".
