I want to write a cross-platform app using Unity3D. One of the features I want is to select an image and post it to a website. On iOS I’d expect some kind of a pop-up asking me to select an image from the gallery or take a photo, on PC I’d expect an open-file dialog to select a file on disk.
Does Unity3D have something like this?
If by “have something like this” you mean it has a built-in function to do that, then the answer is no. Unity doesn’t even have built-in save game functionality.
If you mean; can you write a script that achieves that behavior, yes, you certainly can. But if you don’t already have a general idea of what that script would look like, there is a lot of reading in your future and/or you’re already in over your head.
A 3rd party library would be acceptable
