Unity 2D Game Development, Regular Update and DLC Plans Content update methods and DLC additions after the game launch.

Game development is not just about releasing a game. The lifeblood of a great game lies in
continuously enhancing user experience and maintaining player engagement.
In this blog post, we will take a closer look at how to add regular content updates and
downloadable content (DLC) after developing a 2D game using Unity.

1. The Importance of Regular Updates

Regular game updates are a key factor in providing players with new experiences and
promoting user retention. Through continuous updates,
we can fix bugs in the game, add new features, and improve overall quality.
Additionally, updates serve as an important means of enhancing communication with users and
energizing the community.

1.1 Collecting User Feedback

The starting point for updates is user feedback. Users are likely to raise issues or complaints
that arise during gameplay.
This feedback is instrumental in identifying areas for improvement and
prioritizing necessary enhancements. We can explore ways to collect user opinions using
Unity’s analytics tools or user surveys (questionnaires, feedback forms, etc.).

1.2 Contents and Frequency of Updates

Regular updates should be carried out according to a pre-planned schedule.
For example, updates can be scheduled monthly.
Updates may include the following elements:

  • Bug fixes
  • Game balance adjustments
  • New content additions (levels, characters, items, etc.)
  • UI/UX improvements

By regularly adding new elements,
users will always look forward to something new.

2. The Concept of DLC (Downloadable Content)

DLC is content added after the game’s release,
usually incurring separate costs. It is an important way to provide
additional value to users and extend the game’s lifespan. Types of DLC include:

  • New characters or items
  • Additional story and missions
  • Expansion packs (large content additions)

2.1 Planning and Designing DLC

When planning DLC, one must consider its relevance to the existing game and think about
what content users desire.
Moreover, reviewing how much time and resources the DLC will require is essential.
In this process, it can be crucial to gather user expectations and opinions.

2.2 Considerations

Before producing DLC, the following elements should be considered:

  • Pricing strategy: Assess how many users will purchase this DLC
  • Marketing: Develop a marketing strategy to encourage user engagement during the DLC release
  • Technical aspects: Ensure technical compatibility for smooth integration with the existing game

3. How to Add Content Updates and DLC in Unity

3.1 Implementing an Update System

One way to implement a regular update system in Unity is by using scripts to communicate with
the server to receive the latest update information. This sample code demonstrates
how to implement the UpdateManager class using UnityWebRequest: 


using UnityEngine;
using UnityEngine.Networking;

public class UpdateManager : MonoBehaviour
{
    private const string updateURL = "https://YOUR_SERVER_URL/updates.json";

    void Start()
    {
        StartCoroutine(CheckForUpdates());
    }

    private IEnumerator CheckForUpdates()
    {
        UnityWebRequest request = UnityWebRequest.Get(updateURL);
        yield return request.SendWebRequest();

        if (request.result == UnityWebRequest.Result.ConnectionError || 
            request.result == UnityWebRequest.Result.ProtocolError)
        {
            Debug.LogError("Error fetching updates: " + request.error);
        }
        else
        {
            ProcessUpdates(request.downloadHandler.text);
        }
    }

    private void ProcessUpdates(string json)
    {
        // JSON parsing and update application logic
        Debug.Log("Updates available: " + json);
    }
}

3.2 Adding DLC

The method for adding DLC also involves configuring
a download and installation program through scripts in Unity. Each game’s
DLC should be packaged separately so it can be purchased and applied via Steam or other platforms.
Here’s a simple sample code for downloading DLC content: 


using UnityEngine;
using UnityEngine.Networking;

public class DLCManager : MonoBehaviour
{
    private const string dlcURL = "https://YOUR_SERVER_URL/dlc.zip";

    public void DownloadDLC()
    {
        StartCoroutine(DownloadDLCCoroutine());
    }

    private IEnumerator DownloadDLCCoroutine()
    {
        UnityWebRequest request = UnityWebRequest.Get(dlcURL);
        yield return request.SendWebRequest();

        if (request.result == UnityWebRequest.Result.ConnectionError || 
            request.result == UnityWebRequest.Result.ProtocolError)
        {
            Debug.LogError("Error downloading DLC: " + request.error);
        }
        else
        {
            Debug.Log("DLC downloaded successfully!");
            // Add DLC file installation logic
        }
    }
}

4. Conclusion

In developing Unity 2D games, regular updates and the addition of DLC
are crucial strategies for maintaining a sustained relationship with users
and extending the game’s lifespan. Based on the content covered in this article,
create suitable update and DLC strategies for your game to provide users
with unforgettable experiences.

To continue providing enjoyment to players after a game is released,
continuous updates and new content supply are essential.
Such efforts will play an important role in ensuring that the game is cherished
long beyond its initial success.
