### Running in a Sandbox

Windows (tested with Sandboxie):

- Due to a lack of permissions, Rewired is unable to receive device information from Raw Input when run inside a sandbox. Joysticks will not work properly in Raw Input mode. (As a note, Unity itself is also unable to receive this information, rendering joystick support in Unity broken under the default security settings.)
- Direct Input mode is able to receive joystick input, but joystick plug/unplug notifications are blocked, so hot-plugging does not work properly even in Direct Input mode.

### Windows App Store support not working in Unity 5.0.0, fixed in 5.0.1

Due to a new bug introduced in Unity 5.0.0, Rewired is unable to be compiled in this version of Unity. The bug was fixed in Unity 5.0.1, so upgrade to 5.0.1 if you need Windows App Store support.

### Android remotes are not detected (Nexus Player, Amazon Fire TV, Razer Forge TV, etc.)

These remotes may not work on versions of Unity 5.02 or greater. Unity introduced a new bug in this version that makes the remote appear with a NULL name in the Input.GetJoystickNames array, which also happens to be used to fill the array entry when a controller is no longer connected. There is no way to identify these remotes because of this. The bug still exists as of 5.3.4f1. It has been reported and this information will be updated if a fix is issued.

The remotes will however still return keycodes through UnityEngine.Input. Most remotes use the keyboard arrow keycodes for movement. In addition, there are various workarounds possible using Custom Controllers such as shown in the following code example:

    // Copyright (c) 2016 Augie R. Maddox, Guavaman Enterprises. All rights reserved.

    /*  Unity has a significant bug that prevents remotes from being recognized and handled as joysticks in Rewired.
        Therefore, the only workaround is to read the remote as (mostly) keyboard keys through UnityEngine.Input
        directly and feed this input to a Custom Controller. This script will read keyboard keys and
        Joystick Button 0 (on all joysticks) to determine the values to feed into the Custom Controller.

        To Use:
        1. Create a gameobject in the scene and assign this component to it and set the Player Id in the inspector.
        2. Create a Custom Controller in the Rewired Input Manager with 8 buttons and 0 axes.
        3. Asssign the Custom Controller to your Player and give it the tag "AndroidRemote".
        4. Create a Custom Controller Map assigning Actions to each button.
        5. Assign the map to your Player.

        The element order is as follows:
        Button 0 = Up
        Button 1 = Down
        Button 2 = Left
        Button 3 = Right
        Button 4 = Center button
        Button 5 = Back button
        Button 6 = Menu button
        Button 7 = Select button

            controller.SetButtonValue(5, Input.GetKey(KeyCode.Escape)); // Back
            controller.SetButtonValue(6, Input.GetKey(KeyCode.Menu)); // Menu

### Keyboard keys stuck on Linux in Unity 5.1.1

This is not a Rewired issue, it's a Unity bug:
http://forum.unity3d.com/threads/unity-5-1-1-broke-input-for-linux-standalone.335113/

Update to Unity 5.1.2 to fix it.

### Compiler error in 5.1.2 patch releases

Unity made an undocumented breaking change to UnityEngine.EventSystems.PointerInputModule.GetMousePointerEventData(). It now requires int id to be passed. This cannot be fixed automatically in my code until Unity 5.1.3 is released because there is no way to detect a patch version before compile.

More information and a patch:
http://forum.unity3d.com/threads/rewired-advanced-input-for-unity.270693/page-20#post-2216921

### IL2CPP: _p0_marshaled': undeclared identifier error on Unity 5.3.2p1, 5.3.2p2

Unity's 5.3.2p1 patch introduced a new IL2CPP error when building Rewired_Core.dll. This affects all platforms that use IL2CPP including iOS and Windows 10 Universal (IL2CPP scripting backend).

This is not an error in Rewired and there is no workaround for it. The only solution is to revert back to Unity version 5.3.2f1. Unity has announced the bug will be fixed in 5.3.2p3. More details can be found here.

### iOS/tvOS: Game controllers not detected

In Unity versions 5.3.0+, game controllers no longer work in Unity because the XCode project Unity builds does not automatically reference the required GameController framework.

Solution: Manually add a reference to the GameController or GameKit framework in XCode.

More details of this issue and the solution can be found here.

### SDL2: OSX - Editor does not support haptic feedback

Due to a bug in SDL/Unity that causes an editor crash when enabled, haptic feedback (vibration) is not supported in the OSX Editor.

Note: This issue only applies if SDL2 is selected as the input source for OSX Standalone builds.

### SDL2: OSX - XBox 360 Controller does not support vibration

SDL2 does not provide vibration support for the XBox 360 Controller on OSX.

Note: This issue only applies if SDL2 is selected as the input source for OSX Standalone builds.

### SDL2: Windows - XBox 360 Controller does not allow independent control of vibration motors

SDL2's haptic feedback system only accounts for a single motor for rumble devices.

Note: This issue only applies if SDL2 is selected as the input source for Windows Standalone builds.

### Steam Streaming / Steam Link: Windows Standalone

Steam Streaming and the Steam Link only work with XInput compatible devices (XBox 360, XBox One, Logitech F310, etc.) and the Steam Controller and only if Use XInput is enabled in the Rewired Editor - Settings page. It is not possible to use Raw Input or Direct Input devices with Steam Streaming. This is not a limitation of Rewired -- it is a limitation of Steam.

Also, when using XInput devices with XInput enabled, Windows is limited to a maximum of 4 devices. Again, this is a limitation of XInput, not Rewired. See this for information on supporting more than 4 XInput devices.

### Apple TV Siri Remote gyroscope does not work

The Apple TV SDK does not expose the raw gyroscope data and thus it is unavailable. The only data that is avalilable is the gravity vector and user acceleration.

### Windows Platforms: XInput devices on Windows appear as "XInput Gamepad"

On Windows, with Use XInput enabled, and always on Windows App Store and Windows 10 Universal builds, there's no way to differentiate one XInput controller type from another. To XInput, everything is simply Gamepad with an id of 0-3. This is not a Rewired issue, it is a design decision by Microsoft.
There is no possible way to associate an XInput id to the matching HID device to get its name and make it be recognized as a specific controller. Because of this, you cannot identify an XInput controller by name in Windows when XInput is enabled. This also affects which controller maps are loaded for this joystick in Windows when using XInput. Since the device is simply and Xinput device, it will be loaded from the XBox 360 controller definition, not the Logitech F310, for example. (However, if you create your controller maps using the Dual Analog Gamepad Template, you don't even need to worry about this.)

The only way you will be able to identify these controllers by name is to disable Use XInput in the Rewired Input Manager (applies to Windows Standalone only, not Windows App Store or Windows 10 Universal -- XInput cannot be disabled on these platforms). Once you do that, you introduce new issues/limitations:

1. L/R triggers are treated as 1 combined axis and both cannot be pressed simultaneously without canceling each other out.
2. You lose universal XInput controller support because each XInput controller now must be specifically recognized and mapped. Any unrecognized XInput devices will be treated as Unknown Controllers.
3. Vibration is not supported without XInput enabled.
4. The Steam Controller as well as Steam Streaming and Steam Link can no longer be supported.

### Windows Platforms: All XInput devices use the Xbox 360 Controller map when "Use XInput" is enabled

As explained in the previous topic, when Use XInput is enabled and always on Windows App Store and Windows 10 Universal builds, there is no way to differentiate one XInput device from another by name or product/vendor id. Therefore, all XInput devices will use the Xbox 360 Controller map on Windows when Use XInput is enabled. This will match all XInput devices, generic or not, and will provide full coverage of all XInput devices. You cannot map these devices based on the individual device type such as Xbox One or Logitech F310 when using XInput because the device cannot be identified as as specific device type but rather simply as an XInput gamepad. All XInput gamepads will use Xbox 360 Controller profile when Use XInput is enabled.

If you disable Use XInput, you will get device-specific identification and recognition (Windows Standalone only, not Windows App Store or Windows 10 Universal), but you will also have the drawbacks explained in the previous topic.

There is rarely ever a need to map these controllers individually by using the specific device-type maps. Just create your Joystick Map using the Dual Analog Gamepad Template and it will cover all gamepads listed here regardless of whether or not you have Use XInput enabled.

### More than 4 XBox controllers cannot be used at the same time

Windows Standalone
XInput has a hard limit of 4 devices. This is not a Rewired limitation, it is a limitation in Microsoft's XInput system.

You can mix and match non-XInput devices with XInput devices for a total of more than 4, but you cannot use more than 4 XInput compatible devices simultaneously if XInput is enabled. If you need to support more than 4 XInput controllers, you must disable XInput in the Rewired Editor - Settings page.

Be advised that by disabling "Use XInput" in the Rewired Input Manager, you introduce these new issues/limitations:

1. L/R triggers are treated as 1 combined axis and both cannot be pressed simultaneously without canceling each other out.
2. You lose universal XInput controller support because each XInput controller now must be specifically recognized and mapped. Any unrecognized XInput devices will be treated as Unknown Controllers.
3. Vibration is not supported without XInput enabled.
4. The Steam Controller as well as Steam Streaming and Steam Link can no longer be supported.

OSX Standalone
XBox 360 controllers on OSX require this XBox 360 driver. This driver also imposes the 4-device limit just like XInput. It is currently not possible to use more than 4 XInput devices simultaneously on OSX. Again, you can mix and match non-XInput controllers to achieve a total count greater than 4. Because the driver is required for the controller to be detected, there is no way to disable the use of this driver and get around this issue.

### Windows Standalone (Use XInput enabled, Windows 10 Insider Preview): Game crashes when using or plugging in an XInput-compatible controller.

There have been reports of crashes when using XInput on one or more versions of Windows 10 Insider Preview. The crash can occur either on the start of the application (if an XInput-compatible device is attached) or when any XInput-compatible device is first attached. This issue is not an issue with Rewired but an issue with Windows 10 Insider Preview. I have been unable to reproduce any issue in Windows 10 Insider Preview.

The only possible workaround is to disable Use XInput in the Rewired Input Manager -> Settings -> Windows tab.

Rewired is 100% compliant with Microsoft's published guidelines for using XInput. Rewired works with all versions of XInput from Windows XP - Windows 10 without issue. If you or your customers experience this crash in Windows 10 Insider Preview, please report this error to Microsoft so they can fix it before rolling out the public release.

### Windows Standalone (Unity Fallback, Windows 10): Xbox One Controller L/R and D-Pad mapping problems

Due to Microsoft driver issues, on versions of Windows 10 before the Windows 10 Anniversary Update, the L/R triggers and D-Pad on the Xbox One Controller may be mapped incorrectly and non-functional when using Unity Fallback input. Microsoft made Xbox One Controller driver changes in an early version of Windows 10 that caused the controller mappings to change when retrieving values through the HID driver. This change did not affect XInput. Unity uses a combination of direct HID device access and XInput to get input from XInput compatible devices. This caused the standardized mappings in Unity's input system to break, cross-mapping the D-Pad and the triggers. Microsoft acknowledged this as a mistake and finally rolled back this driver change in the Windows 10 Anniversary Update rolled out on August 2, 2016. After this update, the mappings reverted to the normal mappings consistent with Windows 7. Only users using Windows 10 pre-Anniversary update are affected. This does not affect Rewired if using the native input options instead of Unity fallback input.

### Windows Standalone (Raw Input, Windows 10): XBox One controller causes system crash when removed when using Raw Input on Windows 10

Update: This has been fixed as of Windows 10 Anniversary Update.

This is not a bug or issue with Rewired. A recent Windows Update has introduced a new bug in Windows 10 when using the XBox One controller. When Raw Input is enabled, if the XBox One controller is disconnected at runtime, it will cause the entire system to become unresponsive requiring a hard reboot to fix. I have isolated this issue to a specific Windows API Raw Input function call which is not optional. There is no known workaround for this problem when using Raw Input. This bug has been reported to Microsoft.

The only possible workaround is to enable Use XInput so the XBox One Controller is handled by XInput instead of Raw Input.

### Windows Standalone (Direct Input, Windows 10): Using two or more XBox One controllers will cause Unity to hang when using Direct Input on Windows 10

This is not a bug or issue with Rewired. A recent Windows Update has introduced a new bug in Windows 10 when using multiple XBox One controllers. When Direct Input is enabled, if two or more XBox One controller are attached, it will cause Unity to hang until all but one controller are removed. I have isolated this issue to a specific Windows API Direct Input function call which is not optional. There is no known workaround for this problem when using Direct Input.

The only possible workaround is to enable Use XInput so the XBox One Controller is handled by XInput instead of Direct Input.

### Windows Standalone (Windows 10): Xbox One Controller stops working after another controller is unplugged

Applies to Windows 10 after Anniversary Update.

One or more Xbox One Controllers can stop working after unplugging any other Xbox One Controller. This is an Xbox One Controller driver bug introduced in the Windows Anniversary Update. There is no possible workaround to this issue. If this issue affects your game, please report it to Microsoft. This is not an issue with Rewired.

### Windows Standalone (Windows 10): Game Center popup keeps appearing when pressing keyboard keys

Applies to Windows 10 after Anniversary Update.

When using Xbox One Controllers, At random, the Game Center popup may begin to appear every time a keyboard key is pressed or when clicking to different windows. This is an Xbox One Controller driver bug introduced in the Windows Anniversary Update. There is no possible workaround to this issue. If this issue affects your game, please report it to Microsoft. This is not an issue with Rewired.

### Windows Standalone (Unity Fallback, Windows 10): XBox One controller has incorrect mapping

Microsoft changed the XBox One driver in Windows 10 and changed the mappings compared to Windows 7 and prior versions, then after the Windows 10 Anniversary Update, they reverted this driver change. When using Unity fallback as the input source, it is impossible to differentiate the XBox One controller on Windows 10 pre and post Anniversary Update. Therefore, the decision was made to support only the newest mapping. Xbox One Controllers will have incorrect mappings on Windows 10 prior to the Anniversary Update.

This is not an issue when using Raw Input, Direct Input, or XInput. It is advised that you do not use UnityEngine fallback input as the input source on the Windows Standalone platform due to this and many, many other issues.

### Windows Standalone: Nvidia Shield Controller problems on Raw Input and Direct Input

With newer firmware versions, the Nvidia Shield Controller has major problems on Raw Input and Direct Input which cause massive slowdowns making the controller essentially unusable. The only way to support the controller on Windows is to enable Use XInput which is not subject to the same issues. The Nvidia Shield Controller can no longer be safely used on Windows Standalone without Use XInput enabled until Nvidia fixes the firmware problems. If the controller is used without Use XInput enabled, the frame rate will drop to an extremely low level. There is no possible workaround to this issue.

### Windows 10 Universal IL2CPP: Crash when disconnecting controllers

Update: This bug has been fixed as of Unity 5.3.5p1.

Note: This issue appears to affect builds running in Visual Studio only. It does not appear to affect Master builds that have been deployed.

As of Unity 5.3.4f1, after enabling support for standard HID joysticks in the Package.appxmanifest, Unity may crash when disconnecting a non-XInput controller. This is a bug in Unity, not Rewired and there is no possible workaround if you want to support any controllers besides XInput controllers. (To disable support for non-XInput controllers, remove the tags added to the Package.appxmanifest mentioned here.) This bug has been reported to Unity, but so far no fix has been announced.

This issue does not affect Windows 10 Universal builds when using the .NET scripting backend.

### Windows Editor: <RI.Hid> Failed to create device file: 2 The system cannot find the file specified.

You may see the following error when starting the Unity Editor:

- <RI.Hid> Failed to create device file: 2 The system cannot find the file specified.

This error is logged by Unity itself and is not created by Rewired, nor is it related to Rewired in any way. It cannot be silenced or fixed. There is a forum thread detailing the issue here.

### Ouya SDK: Unity input joysticks do not work when the Ouya SDK is installed

When the Ouya Everywhere SDK is installed in the project, it interferes with Unity's input system on Android builds preventing any joystick axes or buttons from working. At present, there is no known solution to make Unity input work on Android when the Ouya SDK is installed. However, Rewired includes support for the Ouya SDK which will allow you to use the Ouya SDK for joystick input. See the Special Platform Support - Ouya for installation instructions.

### Ouya SDK: Cannot use more than 4 controllers

When using the Ouya Everywhere SDK for joystick support, you cannot use more than 4 controllers. If you attach additional controllers beyond the 4-controller limit, the controller will be assigned to one of the same id's as another controller and both will control the same player. This is a limitation of the Ouya SDK, not Rewired.

### Serialized data corruption after importing Rewired

Unity has a major bug in the Unitypackage importer that can lead to data corruption when importing an asset from the Unity Asset Store or a Unitypackage file.

If your Unity Editor Settings -> Asset Serialization Mode is set to "Force Binary", serialized data may be corrupted when you import a Unitypackage. This often happens when a new Unitypackage is imported. If you then re-import the same package over the previous import, it will be imported correctly. If you then delete the imported files and re-import them, they will be corrupted again.

Corrupted serialized data in Rewired can manifest itself as inexplicable errors and exceptions being thrown for no reason making Rewired completely unusable. The best thing to do in this case is to change the Asset Serialization Mode to "Mixed" or "Force Text" and re-import Rewired. If that's not possible or you don't want to have to wait for all your assets to be re-imported in the new serialization mode, import the Rewired asset twice in a row (do not delete the Rewired folder after the first import). The serialized data should be intact after the second import.

This bug has been reported to Unity. They have been able to reproduce it and have sent it to the developers for resolution. No ETA was given.

Last tested version: Unity 5.3.5f0

Please note that this is a Unity bug and can affect any asset. This is not an issue with Rewired.

### Serialized data corruption after upgrading Unity

Unity's data serializer has bugs which can cause serialized data in scenes and prefabs to become corrupt after upgrading Unity and allowing it to re-import the assets. This normally seems to happen with serialized strings. If you've recently upgraded Unity and you start seeing weird errors or warnings logged about Actions missing that have long nonsense string names, your serialized data may have been corrupted in Unity. There is no way to fix this other than to restore a backup. For this and many other reasons, it's imperative that you back up your project before upgrading Unity.

Please note that this is a Unity bug and can affect any asset. This is not an issue with Rewired.
