Create a method attribute

Take this simple example.

[AttributeUsage(AttributeTargets.Method)]
public sealed class ExampleAttribute : InheritPrebuildAttribute {
    public override string GetContent(System.Reflection.MethodInfo methodInfo, ScriptInfos scriptInfo, uint methID, uint elementUID) {
        return PrebuildAttribute.BaseMethod(methodInfo, "Hello" + methodInfo.Name, CreateMyMethodContent());
    }

    string CreateMyMethodContent() {
        return PrebuildAttribute.Template(MyTemplate,
            "var1", "Hello Prebuild",
            "var2", "test"
        );
    }

    string MyTemplate {
        get {
            return @"
Debug.Log(""${var1}"");
Debug.Log(""${var2}"");
";
        }
    }
}

GetContent is the entry point of method generation.

• methodInfo is the standard Reflection.MethodInfo (name, arguments...)
• scriptInfo contains a lot of informations on the current script
• methID is a unique method id for this script
• elementID is a unique id for this project, it can be changed between each prebuild.

PrebuildAttribute.BaseMethod is a helper to generate a string method based on another method.

PrebuildAttribute.Template is a helper to generate a string and replace variables in.

Here we created a method with the same return but changed the name of 'mymethod' to Hellomymethod.

This script generates this code:

[ExamplePrebuild] // see packer section
public class MyExampleBehaviour : MonoBehaviour {
    [Example]
    void WorldTest() { }

#region Prebuild
private void HelloWorldTest() {
    Debug.Log("Hello Prebuild");
    Debug.Log("test");
}
#endregion
}
