Rename Symbols Plugin

RenameSymbols (UdonObfuscator.Composition.RenameSymbols) plugin renames each symbols (namespace, class, property, method, field, variable, and enum member) with a randomly generated name.

Example

input

namespace AudioLink
{
    public partial class AudioLink
    {
        public void SetMediaVolume(float volume)
        {
            audioMaterial.SetFloat("_MediaVolume", volume);
        }
    }

    public enum MediaPlaying
    {
        None = 0,
        Playing = 1,
        Paused = 2,
        Stopped = 3,
        Loading = 4,
        Streaming = 5,
        Error = 6
    }
}

output

namespace _0xc21b5618
{
    public partial class _0x12771ecc
    {
        public void _0xc842a475(float _0x06b29be3)
        {
            _0xc3be3b48.SetFloat("_MediaVolume", _0x06b29be3);
        }
    }

    public enum _0x524f5ceb
    {
        [global::UnityEngine.InspectorName("None")]
        _0x228290b2 = 0,
        [global::UnityEngine.InspectorName("Playing")]
        _0x933ce6cc = 1,
        [global::UnityEngine.InspectorName("Paused")]
        _0x9088d417 = 2,
        [global::UnityEngine.InspectorName("Stopped")]
        _0x52c8b2af = 3,
        [global::UnityEngine.InspectorName("Loading")]
        _0xd021ab9d = 4,
        [global::UnityEngine.InspectorName("Streaming")]
        _0x27608f68 = 5,
        [global::UnityEngine.InspectorName("Error")]
        _0x06da0cb3 = 6
    }
}

Options

Options:
  --rename-namespaces       rename namespaces [default: False]
  --rename-classes          rename classes [default: False]
  --rename-properties       rename properties [default: False]
  --rename-fields           rename fields [default: False]
  --rename-methods          rename methods without referencing by SendCustomEvent [default: False]
  --with-send-custom-event  rename all methods [default: False]
  --rename-variables        rename local variables [default: False]
  --enum-attributes         add UnityEngine.InspectorName to enum members [default: False]
  --rename-symbols          use rename-symbols [default: False]

If you use keep serialized names, add /* plana:disable */. And if you keep enum display names, add --enum-attributes option.

Rename Namespaces

If you provide --rename-namespaces args, this plugin rename namespace declaration. It supports NamespaceDeclarationSyntax, not working with FileScopedNamespaceDeclarationSyntax.

input

namespace AudioLink {}

output

namespace _0xc21b5618 {}

Rename Classes

warning

Warning This feature broken references between Udon C# Program Asset and C# Script.

important

Important This feature does not yet supported by Unity Integration. If you use this feature, please re-reference between U# Program Asset and C# Script.

If you provide --rename-classes args, this plugin rename class declarations. It supports ClassDeclarationSyntax and EnumDeclarationSyntax.

input

public class AudioLink {}
public enum MediaPlaying {}

output

public class _0x12771ecc {}
public enum _0x524f5ceb {}

Rename Properties

If you provide --rename-properties args, this plugin rename property declarations. It doe's not support to rename backing field of properties.

input

public string[] List { get; }

output

public string[] _0x73a8b924 { get; }

Rename Fields

If you provide --rename-fields args, this plugin rename field declarations.

input

public partial class AudioLink : MonoBehaviour
{
    [Header("Basic EQ")]
    [Range(0.0f, 2.0f)]
    [Tooltip("Warning: this setting might be taken over by AudioLinkController")]
    public float gain = 1f;
}

input

public partial class AudioLink : MonoBehaviour
{
    [Header("Basic EQ")]
    [Range(0.0f, 2.0f)]
    [Tooltip("Warning: this setting might be taken over by AudioLinkController")]
    public float _0x4144d8a1 = 1f;
}

Rename Methods

If you provide --rename-methods args, this plugin rename method declarations.

input

public void SetMediaVolume(float volume)
{
    audioMaterial.SetFloat("_MediaVolume", volume);
}

output

public void _0xc842a475(float volume)
{
    audioMaterial.SetFloat("_MediaVolume", volume);
}

With Send Custom Event

Rename Variables

If you provide --rename-variables args, this plugin renames all local variables. It supports ParameterSyntax#Identifier and VariableDeclaratorSyntax.

input

public void SetMediaVolume(float volume)
{
    audioMaterial.SetFloat("_MediaVolume", volume);
}

output

public void SetMediaVolume(float _0x06b29be3)
{
    audioMaterial.SetFloat("_MediaVolume", _0x06b29be3);
}

Enum Attributes

If you provide --enum-attributes args, this plugin keep the display name on inspector with adding UnityEngine.InspectorNameAttribute.

input

public enum MediaPlaying
{
    None = 0,
}

output

public enum _0x524f5ceb
{
    [global::UnityEngine.InspectorName("None")]
    _0x228290b2 = 0,
}

Serializer Attributes

If you provide --serializer-attributes args, this plugin keep the serializer name on inspector with adding UnityEngine.Serialization.FormerlySerializedAsAttribute.

input

public class AudioLink
{
    public int depth;
}

output

public class AudioLink
{
    [global::UnityEngine.Serialization.FormerlySerializedAs("depth")]
    public int _0x228290b2;
}

Algorithm

This plugin support a lot of renaming algorithms. If you are not provided this args, use hexadecimal by default.

hexadecimal - identifier names like _0x1234abcd
mangled - short identifier names like a, b, aa
mangled-shuffle - same as mangled but with shuffled alphabet

Comments

You can disable obfuscation via comments.

/* plana:disable */

This comment (annotation comment) disabled obfuscation to next syntax only. For example,

/* plana:disable */
public void ExampleMethod()
{
    this._a.SomeMethod();
}

// to

public void ExampleMethod()
{
    this._0x12345678._0x87654321();
}
