My problem is the following. As I need to use System. This caused a problem because as I had algo as reference System, when I write using System. Form and then build the solution, it tells me that it didn't found 'Windows' in 'System' namespace. This is obvious because it didn't had to lookup there.
My problem now is that I can't access the compiler arguments in Unity. You can access the compiler arguments in Unity by creating an smcs. These files are defined in the following doc:.
Add your -reference flag into this file. Note that this file will not re-import automatically - you may need to right-click-reimport a script to refresh the project changes.

Edit: That being said your callstack is always gonna be empty, and double clicking it could cause some very strange issues. NteroOct 5, Code csharp :. InteropServices. I got it to work but I'm missing something here. Worst case I can make a setter. Though, is there a way to do this? Or would I need to pass it to main first.
Log in as listed above. Essentially you have these steps: 1 In C Pass in function you want to call using Marshal. For some reason I'm not able to assign the pointer to my local? I seem to be missing something basic at the moment. They are two very different things, and 2 actually takes 1 as a parameter.More info See in Glossary platform.
To build an application with a native plug-in A set of code created outside of Unity that creates functionality in Unity. There are two kinds of plug-ins you can use in Unity: Managed plug-ins managed.
NET assemblies created with tools like Visual Studio and Native plug-ins platform-specific native code libraries. More info See in Glossary for iOS, follow these steps:. For example, if your native code is iOS-specific, make sure the plug-in is only enabled for iOS. Your app can only call iOS native plug-ins A platform-specific native code library that is created outside of Unity for use in Unity.
Allows you can access features like OS calls and third-party code libraries that would otherwise not be available to Unity. A simple way to implement this is:. Unity iOS supports limited native-to-managed callback functionality. This is the more complex option. When you use delegates, the method on the C side must be static and be marked with the MonoPInvokeCallback attribute.
You must pass the method as a delegate to the extern method which is implemented in native code as a function that takes a pointer to function with the corresponding signature. The function pointer in the native code then leads back to the C static method. Unity supports automated plug-in integration and copies all files with the following extensions to the generated Xcode project if you enable them for iOS in the Plugin Inspector A Unity window that displays information about the currently selected GameObject, Asset or Project Settings, alowing you to inspect and edit the values.
More info See in Glossary window:. If you change these files in Xcode, you must copy them back into your Unity Project. Otherwise, Unity will overwrite them the next time you build your Project. Managed-to-unmanaged calls are quite processor-intensive on iOS. Try to avoid calling multiple native methods per frame. Wrap your native methods with an additional C layer that calls native code on the device and returns dummy values in the Editor.
String values returned from a native method should be UTF—8 encoded and allocated on the heap. Mono marshalling calls free for strings like this. You can download a simple example of how to use a native code plug-in here: Bonjour Browser Sample. This example demonstrates how you can invoke bjective-C code from a Unity iOS application. This application implements a simple Bonjour client and consists of:. Version: Language : English.October 30, Leave a comment. This allows easy integration of native library functions to both pass and receive data between Unity managed C and native platform code.
Basic concept is simple. Mono handles things mostly automatically from there on. Some care is required to do this efficiently. C PInvoke defines marshaling as a protocol to serialize and deserialize managed objects back and forth towards native code.
This may generate lot of overhead. Strings are passed and returned as character arrays. Array handling is similar to the string arrays.
Most objects can be passed as is but if they have array properties those must be of fixed size. Many of these examples can be done in cleaner way using MarshalAsAttribute.
