Attribute Injector is an attribute-based framework for creating and injecting inline codes into your projects.

A code injection built for use in Unity3D. Implemented using Mono.Cecil.

Attribute Injector is a library that applies code injection to methods with additional attributes without the need to extend and create a new methods for each functionality. You can ensure project integrity with very little attributes.

[Injection]
public class SimpleLog : Attribute
{
    [Rise(When.OnEntry)]
    public void SomeMethod([Argument(Method.Name)] string name)
    {
        Debug.Log($"Entering method {name}");
    }
}

[SimpleLog]
public void DoSomething() 
{ 
    Debug.Log("body of DoSomething method");
}

DoSomething(); //call the method anywhere...

Entering method 'DoSomething'
body of DoSomething method

[Injection]
public class ComplexLog : Attribute
{
    [Rise(When.OnEntry)]
    public void Begin([Argument(Method.Name)] string name)
    {
        Debug.Log($"Entering method {name}");
    }

    [Rise(When.OnExit)]
    public void End([Argument(Method.Name)] string name, [Argument(Method.ReturnValue)] int value)
    {
        //you can reach return value of method.
        Debug.Log($"Exiting method {name} with return value: {value.ToString()}");
    }
}

[ComplexLog]
private int DoSomething() //notice return type
{
    var x = Random.Range(1, 1000);
    Debug.Log("DoSomething body");
    return x;
}

Entering method 'DoSomething'
DoSomething body
Exiting method 'DoSomething' with return value: 126

Before install the addon, you should check the requirements.

• Supports only projects that can reference netstandard3.5+ libraries. Make sure PlayerSettings -> Api Compatibility Level is set to .NET 4.X
• In order for the addon to work, you need to add Mono Cecil package.
• Works with Unity 2017+

For Mono Cecil installation:

1. In Unity, open Window -> Package Manager.

2. Press the + button, choose "Add package from git URL..."

3. Enter "[email protected]" and press Add.

Project supports Unity Package Manager. To install the project as a Git package do the following:

1. In Unity, open Window -> Package Manager.
2. Press the + button, choose "Add package from git URL..."
3. Enter "https://github.com/muveso/AttributeInjector.git#upm" and press Add.

Alternatively, you can add the code directly to the project:

1. Clone the repo or download the latest release.
2. Add the AttributeInjector folder to your Unity project or import the .unitypackage

On the Project Window, right-click and create Attribute Injector -> Settings.

This scriptable object holds all assemblies as cache for performance optimization. If you remove it, all injection process will be canceled.
