Unlocking the Secrets of UE4 Localization Files with CUE4Parse

How to Read UE4 Localization Files with CUE4Parse

Now that we’ve covered the basics, let’s dive into the meat of the article – how to read UE4 localization files with CUE4Parse. We’ll go through a step-by-step guide on how to get started with CUE4Parse and extract data from localization files.

Step 1: Install CUE4Parse

Before we begin, you’ll need to install CUE4Parse. You can do this by installing the NuGet package or by cloning the repository from GitHub.

Install-Package CUE4Parse

Step 2: Load the Localization File

Once you have CUE4Parse installed, let’s load a localization file. You can do this by using the `LocalizationFile` class and passing the path to your `.locres` file.

using CUE4Parse;

var localizationFile = new LocalizationFile("path/to/your/file.locres");

Step 3: Extract Data from the Localization File

Now that we have the localization file loaded, let’s extract some data! CUE4Parse provides several methods for extracting data, including `GetKeys()`, `GetValues()`, and `GetKeyValuePairs()`. For this example, we’ll use the `GetKeyValuePairs()` method to extract all key-value pairs from the file.

var keyValuePairs = localizationFile.GetKeyValuePairs();

foreach (var pair in keyValuePairs)
{
    Console.WriteLine($"Key: {pair.Key}, Value: {pair.Value}");
}

Step 4: Filter and Manipulate the Data

Let’s say you want to filter the data based on a specific condition or manipulate the values in some way. CUE4Parse provides several methods for doing so. For example, you can use the `Where()` method to filter the data based on a condition.

var filteredKeyValuePairs = keyValuePairs.Where(pair => pair.Key.StartsWith("MY_NAMESPACE"));

foreach (var pair in filteredKeyValuePairs)
{
    Console.WriteLine($"Key: {pair.Key}, Value: {pair.Value}");
}

Step 5: Save the Changes (Optional)

If you’ve made changes to the data, you can save the changes back to the localization file. CUE4Parse provides a `Save()` method for doing so.

localizationFile.Save("path/to/your/file.locres");

Common Use Cases for CUE4Parse

CUE4Parse is a versatile tool that can be used in a variety of scenarios. Here are some common use cases:

• Localization testing**: Use CUE4Parse to automate localization testing and ensure that your game’s text is correctly translated.
• Automation**: Use CUE4Parse to automate tasks, such as extracting data from localization files or generating reports.
• Custom tools**: Use CUE4Parse to create custom tools that cater to your specific needs, such as a localization editor or a translation management system.
• Integration with other systems**: Use CUE4Parse to integrate with other systems, such as a translation management system or a project management tool.
