How do I access the "product name" in Unity 4?

Question

I would like to access my app name in a Unity C# script; I've found PlayerSettings.productName, however it requires UnityEditor, which is only available in the editor.

So, in a normal application, how am I supposed to access its name, as it appears in the "product name" field of the player settings?

• It must be cross-platform
• retrieving the executable name (or directory) does not count
• duplicating data does not count (obviously I can create a const with the same name, the whole point of this question is to avoid doing that)

(since the goal is to avoid duplicating data, backwards techniques such as having a const, and using that const to update PlayerSettings.productName is ok, as long as they require no extra step, i.e. they can be made to "run" automatically at compile time)

Answer 1

I don't believe it's possible simply, i.e. there's not an API in some UnityEngine class that will let you get it at runtime that you simply haven't found.

There are two ways of going about this really. The first is to slave the productName variable to a static constant in your scripts that you can also access at runtime. I.e. add a static readonly string to a game class/script. Then add a step to your build process (which exists in the context of the Editor) that forcibly sets PlayerSettings.productName to be the same as your own value.

The second way would be to save a data file in Resources with your product name in it as part of your build process. As in, as a pre-build step, look up what PlayerSettings.productName is and save it out into a text file in an Assets/Resources sub-folder called 'productName.txt'. Then at runtime, call Resources.Load("productName") as TextAsset, and parse the productName out of the text asset.

Personally I'd say that both approaches are more work than they're worth, and you should simply have two copies of the name. Maybe add an Editor verification function that you can habitually call to double check that they're still in-sync during development and prior to making a release.

//Save bundleVersion in PlayerPrefs and access it from anywhere
//This class must be in "Editor" folder to work

using UnityEngine;
using UnityEditor;
using System.IO;

[InitializeOnLoad]
public class BundleVersionChecker
{

    static BundleVersionChecker () 
    {
        string bundleVersion = PlayerSettings.bundleVersion;
        PlayerPrefs.SetString("Key_AppBundleVersion", bundleVersion);
    }

}

I thought you were looking for:

UnityEditor.PlayerSettings.productName

But I then realized you want this at runtime. Because the project needs to keep the same name as the folder its in, you can use something like this.

public string GetProjectName() {
    string[] s = Application.dataPath.Split('/');
    string projectName = s[s.Length - 2];
    return projectName;
}
