Player Settings

Switch to Scripting

Player Settings is where you define various parameters (platform specific) for the final game that you will build in Unity. Some of these values for example are used in the Resolution Dialog that launches when you open a standalone game, others are used by XCode when building your game for the iOS devices, so it’s important to fill them out correctly.

To see the Player Settings choose Edit->Project Settings->Player from the menu bar.

API Compatibility Level

You can choose your mono api compatibility level for all targets except the webplayer. Sometimes a 3rd party .net dll will use things that are outside of the .net compatibility level that you would like to use. In order to understand what is going on in such cases, and how to best fix it, get “Reflector” on windows.

1. Drag the .net assemblies for the api compatilibity level in question into reflector. You can find these in Frameworks/Mono/lib/mono/YOURSUBSET/
2. Also drag in your 3rd party assembly.
3. Right click your 3rd party assembly, and select “Analyze”.
4. In the analysis report, inspect the “Depends on” section. Anything that the 3rd party assembly depends on, but is not available in the .net compatibility level of your choice will be highlighted in red there.

Note that for security reasons, Unity will save neither the keystore password nor the key password. Also, note that the signing must be done from Unity’s player settings - using jarsigner will not work. The unsigned debug keystore is located by default at ~/.android/debug.keystore on OS X and %USERPROFILE%\.android\debug.keystore on Windows.

Optimize Mesh Data	Remove any data from meshes that is not required by the material applied to them (tangents, normals, colors, UV).

Details

The Player Settings window is where many technical preference defaults are set. See also Quality Settings where the different graphics quality levels can be set up.

Publishing a web player

Default Web Screen Width and Default Web Screen Height determine the size used in the html file. You can modify the size in the html file later.

Default Screen Width and Default Screen Height are used by the Web Player when entering fullscreen mode through the context menu in the Web Player at runtime.

Customizing your Resolution Dialog

You have the option of adding a custom banner image to the Screen Resolution Dialog in the Standalone Player. The maximum image size is 432 x 163 pixels. The image will not be scaled up to fit the screen selector. Instead it will be centered and cropped.

Publishing to Mac App Store

Use Player Log enables writing a log file with debugging information. This is useful to find out what happened if there are problems with your game. When publishing games for Apple’s Mac App Store, it is recommended to turn this off, because Apple may reject your submission otherwise. See this manual page for further information about log files.

Use Mac App Store Validation enables receipt validation for the Mac App Store. If this is enabled, your game will only run when it contains a valid receipt from the Mac App Store. Use this when submitting games to Apple for publishing on the App Store. This prevents people from running the game on any computer then the one it was purchased on. Note that this feature does not implement any strong copy protection. In particular, any potential crack against one Unity game would work against any other Unity content. For this reason, it is recommended that you implement your own receipt validation code on top of this using Unity’s plugin feature. However, since Apple requires plugin validation to initially happen before showing the screen setup dialog, you should still enable this check, or Apple might reject your submission.

iOS

Bundle Identifier

The Bundle Identifier string must match the provisioning profile of the game you are building. The basic structure of the identifier is com.CompanyName.GameName. This structure may vary internationally based on where you live, so always default to the string provided to you by Apple for your Developer Account. Your GameName is set up in your provisioning certificates, that are manageable from the Apple iPhone Developer Center website. Please refer to the Apple iPhone Developer Center website for more information on how this is performed.

Stripping Level (Pro-only)

Most games don’t use all necessary dlls. With this option, you can strip out unused parts to reduce the size of the built player on iOS devices. If your game is using classes that would normally be stripped out by the option you currently have selected, you’ll be presented with a Debug message when you make a build.

Script Call Optimization

A good development practice on iOS is to never rely on exception handling (either internally or through the use of try/catch blocks). When using the default Slow and Safe option, any exceptions that occur on the device will be caught and a stack trace will be provided. When using the Fast but no Exceptions option, any exceptions that occur will crash the game, and no stack trace will be provided. However, the game will run faster since the processor is not diverting power to handle exceptions. When releasing your game to the world, it’s best to publish with the Fast but no Exceptions option.

Android

Bundle Identifier

The Bundle Identifier string is the unique name of your application when published to the Android Market and installed on the device. The basic structure of the identifier is com.CompanyName.GameName, and can be chosen arbitrarily. In Unity this field is shared with the iOS Player Settings for convenience.

Stripping Level (Pro-only)

Most games don’t use all the functionality of the provided dlls. With this option, you can strip out unused parts to reduce the size of the built player on Android devices.

Windows Store Apps

Most of these settings are transferred to Package.appxmanifest when creating Visual Studio solution for the first time.

Note: If you build your project on top of the existing one, Unity won’t overwrite Package.appxmanifest file if it’s already present, that means if you change something in Player Settings be sure to check Package.appxmanifest, if you want Package.appxmanifest to be regenerated, simply delete it, and rebuild your project from Unity.

To read more about App package manifest, please visit http://msdn.microsoft.com/en-us/library/windows/apps/br211474.aspx.

Settings from Packaging, Application UI, Tile, Splash screen, Capabilities directly transfer to settings in Package.appxmanifest file.

Certificate

Every Windows Store App needs a certificate which identifies a developer, Unity will create a default certificate, if you won’t provide your own.

Compilation

As you know, Unity uses Mono when compiling script files, and you can use the API located in .NET 3.5. Compilation Overrides allows you to use .NET for Windows Store Apps (also known as .NET Core) in your C# files, the API is available here.

When Compilation Overrides is set to:

1. None - C# files are compiled using Mono compiler.
2. Use .Net Core - C# files are compiled using Microsoft compiler and .NET Core, you can use Windows Runtime API, but classes implemented in C# files aren’t accessible from JS or Boo languages. Note: when using API from Windows Runtime, it’s advisable to wrap the code with NETFX_CORE define, because the API is only avaible when building to Windows Store Apps, and it’s not available in Unity Editor.
3. Use .Net Core Partially - C# files not located in Plugins, Standard Assets, Pro Standard Assets folders are compiled using Microsoft compiler and .NET Core, all other C# files are compiled using Mono compiler. The advantage is that classes implemented in C# are accessible from JS and Boo languages.

Note: You won’t be able to test .NET Core API in Unity Editor, because it doesn’t have access to .NET Core, so you’ll be able to test the API only when running Windows Store App.

Note: You cannot use .NET Core API in JS or Boo scripts.

Here’s a simple example how to use .NET Core API in scripts.

string GetTemporaryFolder()
{
#if NETFX_CORE
    return Windows.Storage.ApplicationData.Current.TemporaryFolder.Path;
#else
    return "LocalFolder";
#endif
}

Misc

Unprocessed Plugins contains a list of plugins which are ignored by Unity’s preprocessing tools (like SerializationWeaver, AssemblyPreprocessor, rrw), usually you don’t need to modify this list, unless you’re getting an error that Unity’s failed to preprocess your plugin.

What will happen if you’ll add a plugin to this list?

Unity won’t inject additional IL code into your assembly used for serialization purposes, but if you’re plugin isn’t referencing UnityEngine.dll, that’s totally fine, because Unity won’t serialize any data from your plugin.

Independent Input Source

Let’s you enable an option for independent input source, you can read more here. Basically this makes your input more responsive, and usually you want this option to be enabled.

Low Latency Presentation API

Let’s you enable Low Latency Presentation API, basically this create D3D11 swapchain with DXGI_SWAP_CHAIN_FLAG_FRAME_LATENCY_WAITABLE_OBJECT flag, read more here and should increase input responsiveness. This option is disabled by default because on hardware with older GPU drivers, this option makes game laggy, if you enable this option - be sure to profile your game if the performance is still acceptable.

Capabilities

These options are directly copied to Package.appxmanifest.

Note:_ If you’re build your game on top of previous package, Package.appxmanifest won’t be overwritten.
