Danganronpa-like Game Episode 1 Editor setup

Introduction

This tutorial will guide you through the process of setting up a Unity editor extension for creating a Danganronpa-like game. In this first episode, we will focus on designing a Court Case using a node editor approach, making it easier to visualize and manage your game’s logic and flow.

Step 1: Setting Up Your Unity Project

• Create a New Unity Project

  • Open Unity Hub and click on "New Project."
  • Choose the template (2D or 3D) based on your game design.
  • Name your project (e.g., "DanganronpaLikeGame") and select a location for it.

• Download Required Assets

  • Access the asset package provided in the video description: Download Assets.
  • Import the downloaded assets into your Unity project by dragging them into the Assets folder or using the "Assets" > "Import Package" > "Custom Package" option.

Step 2: Creating the Editor Extension

• Open the Script Editor

  • In Unity, go to the "Assets" folder and create a new folder named "Editor."
  • Inside the "Editor" folder, create a new C# script (e.g., "CourtCaseEditor.cs").

• Write the Basic Editor Script

  • Open the newly created script in your preferred code editor (e.g., Visual Studio).
  • Start by defining the editor window class and setting up the basic structure:

using UnityEditor;
using UnityEngine;

public class CourtCaseEditor : EditorWindow
{
    [MenuItem("Window/Court Case Editor")]
    public static void ShowWindow()
    {
        GetWindow<CourtCaseEditor>("Court Case Editor");
    }

    private void OnGUI()
    {
        // Add GUI elements here
    }
}

• Add GUI Elements
  • Within the OnGUI method, you can add buttons, fields, and other UI elements that will help in designing the Court Case. For example, you might want to add a button to create a new case or input fields for case details.

Step 3: Implementing the Node Editor

• Set Up Node Structure
  • Define a simple class for your nodes, which can represent different parts of the Court Case (e.g., evidence, testimony).

public class CourtCaseNode
{
    public string nodeName;
    // Add properties relevant to your node
}

• Visualize Nodes in the Editor

  • Use Unity's GUI functions to draw your nodes on the editor window. Consider using GUILayout for layout management.

• Implement Drag and Drop Functionality

  • Allow users to create and connect nodes visually. This involves handling mouse events and drawing connections between nodes.

Step 4: Saving and Loading Cases

• Create Serialization Methods
  • Implement methods to save your Court Case data, ensuring it can be loaded back into the editor later. Use Unity’s JsonUtility for easy serialization.

public void SaveCourtCase(CourtCaseNode[] nodes)
{
    string json = JsonUtility.ToJson(nodes);
    System.IO.File.WriteAllText("path/to/savefile.json", json);
}

• Load Cases from File
  • Create a function to load saved cases, parsing the JSON back into your node structure.

Conclusion

In this tutorial, you learned how to set up a Unity project for a Danganronpa-like game and create an editor extension for designing Court Cases. You implemented a basic node editor, allowing for a more intuitive design process.

Next Steps

• Explore adding more features to your node editor, such as customizing node properties.
• Consider integrating a visual scripting system for more complex game mechanics.
