Create a field attribute

Take this simple example.

[AttributeUsage(AttributeTargets.Field)]
public sealed class ExampleAttribute : InheritPrebuildAttribute {
    public override string GetContent(System.Reflection.FieldInfo fieldInfo, ScriptInfos scriptInfo, uint fieldID, uint elementUID) {
        // create name _name => Name
        var name = fieldInfo.Name.Replace("_", "");
        name = name.Substring(0, 1).ToUpperInvariant() + name.Substring(1);

        // get type string
        var type = UnityBitConverter.GetStringOfType(fieldInfo.FieldType);

        return PrebuildAttribute.Template(MyTemplate,
            "baseName", fieldInfo.Name,
            "name", name,
            "type", type
        );
    }

    string MyTemplate {
        get {
            return @"
public ${type} ${name} {
    get {
        return ${baseName};
    }
}
";
        }
    }
}

GetContent is the entry point of method generation.

• fieldInfo is the standard Reflection.FieldInfo (name, type...)
• scriptInfo contains a lot of informations on the current script
• fieldID is a unique field id for this script
• elementID is a unique id for this project, it can be changed between each prebuild.

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

Here we created a property MyField from _myField;

This script generates this code:

[ExamplePrebuild] // see packer section
public class MyExampleBehaviour : MonoBehaviour {
    [Example]
    int _test;

#region Prebuild
public int Test() {
    get {
        return _test;
    }
}
#endregion
}
