I wanted to use ZXing library and to check some demos first. Website says:
The following demo clients are available: -Unity3D and Vuforia demo (demonstrates encoding of barcodes and decoding of images from a camera with Unity3D)
I downloaded it, and it just a bunch of DLL files:
How do I run it in unity? This is supposed to be some sort of sample or demo, because demos for other platforms, like windows, contain .EXE files.
You should try the whole demo project. https://zxingnet.svn.codeplex.com/svn/trunk/Clients/UnityDemo/ I think that will make the use of the libraries much clearer.
