A question which comes up very often is the following:
Can I use MatriX with Unity 3d?
Of course you can. Many of our customers are using it with great success in their Unity projects.
Unity is based on Mono. MatriX is designed for cross platform and works on all major .NET platforms, including Mono.
Many Unity developers have some problems to get started with MatriX on Unity.
This post should be a small tutorial and address some of the issues you may be facing during your Unity development.
1) Download the correct MatriX dll (Mono build). MatriX builds are not universal, which means you need to download and reference the MatriX library for Mono.
You can get the latest Mono build from NuGet here:
2) MatriX requires System.Xml.Linq.dll. Make sure that you reference System.Xml.Linq in your project as well and add it to your assets. Otherwise Unity may throw an exception when you run your project.
3) Depending on your Unity version you may get compiler errors on iOS. When you use the latest Unity version this should be no problem. On older Unity versions this problem is related to obfuscation. To resolve this please contact us directly.
4) The iOS stripping feature causes problems. It does not work when reflection gets used. The core Xml serializing engine in MatriX is build on reflection using a factory pattern. You either have to remove stripping from your complete project, or exclude the MatriX classes.
Here is an example of a link.xml file excluding all MatriX classes:
<linker> <assembly fullname="Matrix"> <type fullname="Matrix.*" preserve="all"/> </assembly> <assembly fullname="mscorlib"> <namespace fullname="System.Security.Cryptography" preserve="all" /> </assembly> </linker>
It looks like disabling all stripping in Unity is not enough and the link.xml file above must exist.
5) Some of our users reported that connecting to an XMPP server does not work inside the Unity editor because of some networking problems of the IDE. When the code gets executed or published on a device it works fine. This is a restriction of Unity and not related to MatriX.
