This plugin is used to retrieve distribution channel identifiers for multiple platforms in Unity projects (iOS, tvOS, visionOS, Android, Editor, PC, WebGL, UWP, and consoles). It is a submodule of the https://github.com/GameFrameX/GameFrameX project.

Features

• Multi-platform support: iOS, tvOS, visionOS, Android, Editor, PC (Windows/Mac/Linux), WebGL, UWP, PS4, PS5, Xbox One, Nintendo Switch.
• Provides a simple API to retrieve predefined channel information.
• Automatically adds a default channel to Info.plist during iOS builds (if not already set).

Installation

You can add this plugin to your Unity project in one of the following three ways:

1. Add via manifest.json: Add the following to the dependencies node in the manifest.json file in your project's Packages directory:

   {
     "dependencies": {
       "com.gameframex.unity.getchannel": "https://github.com/gameframex/com.gameframex.unity.getchannel.git",
       // ... other dependencies
     }
   }

2. Via Unity Package Manager using Git URL: In the Unity Editor, open Window -> Package Manager. Click the + button in the top-left corner and select Add package from git URL.... Enter the following URL and click Add:

   https://github.com/gameframex/com.gameframex.unity.getchannel.git
   

3. Download or Clone Repository: Download or clone this repository into the Packages directory of your Unity project. Unity will automatically recognize and load the plugin.

Usage

1. Getting Channel Information

In your C# scripts, use the BlankGetChannel.GetChannelName(string key) method to retrieve channel information. The key parameter is the key name you used when setting up the channel information on the corresponding platform.

Example Code:

using UnityEngine;

public class MyGameScript : MonoBehaviour
{
    void Start()
    {
        // Get default channel (key name is "channel")
        string channel = BlankGetChannel.GetChannelName();
        Debug.Log("Current channel: " + channel);

        // Get channel with a specific key
        string customChannel = BlankGetChannel.GetChannelName("channelName");
        Debug.Log("Custom channel: " + customChannel);

        // Get channel with a default fallback value
        string subChannel = BlankGetChannel.GetChannelName("sub_channel", "unknown");
        Debug.Log("Sub channel: " + subChannel);
    }
}

2. iOS / tvOS / visionOS Platform Setup

For iOS, tvOS, and visionOS platforms, the plugin includes a build post-processor (PostProcessBuildHandler.cs). When building, if the project's Info.plist file:

• Does not have a key named channel, the script will automatically add an entry with key channel and value default.
• Already has a key named channel, no modifications will be made.

You can modify the channel value in the Xcode project's Info.plist file, or use your custom key name when calling BlankGetChannel.GetChannelName() (ensure that key name exists in Info.plist).

Info.plist Configuration Example:

<key>channel</key>
<string>ios_cn_taptap</string>

<key>sub_channel</key>
<string>beta</string>

3. Android Platform Setup

For the Android platform, you need to define channel information in the AndroidManifest.xml file. This is typically done by adding <meta-data> tags within the <application> tag.

For example, if you want to use the key name channel and value android_cn_taptap:

<application ...>
    <activity ...>
        ...
    </activity>

    <meta-data
        android:name="channel"
        android:value="android_cn_taptap" />

    <meta-data
        android:name="sub_channel"
        android:value="beta" />

    <!-- other meta-data -->
</application>

Then, you can retrieve this value in C# code using BlankGetChannel.GetChannelName("channel").

4. Editor / PC / WebGL / UWP / Console Platforms Setup

For Editor, PC (Windows/Mac/Linux), WebGL, UWP, PS4, PS5, Xbox One, Nintendo Switch, and other platforms, you need to create a text file named application_config.txt in the Resources folder of your Unity project.

application_config.txt File Format Example:

channel=editor_cn_test
sub_channel=beta
other_key=other_value

Each line format is: key=value

The plugin will automatically read the key-value pairs from this file and cache them for subsequent use.

Notes

• Ensure that the key you use when calling BlankGetChannel.GetChannelName(string key) matches the key name you set in the corresponding platform's configuration file:
  • iOS / tvOS / visionOS: Info.plist file
  • Android: <meta-data> tags in AndroidManifest.xml file
  • Editor / PC / WebGL / UWP / Console Platforms: Resources/application_config.txt file
• The plugin includes a link.xml file to prevent code from being removed by Unity's code stripping feature.
• The GetChannelName() method caches channel information to avoid repeated reading of configuration files, improving performance.
