How do I implement inverted camera controls as an option in my game’s settings menu in Unity?

Implementing Inverted Camera Controls in Unity

Step 1: Create a Toggle Option in the UI

• In Unity, create a new Toggle in your settings menu UI. This will serve as the option for the player to enable or disable inverted controls.
• Ensure it’s labeled appropriately for clarity, such as ‘Invert Y-Axis’.

Step 2: Scripting the Control Logic

Create a C# script to handle the input changes:

using UnityEngine;

public class CameraController : MonoBehaviour
{
    public bool invertYAxis = false;
    public float sensitivity = 5.0f;

    void Update()
    {
        float mouseX = Input.GetAxis("Mouse X") * sensitivity;
        float mouseY = (invertYAxis ? -1 : 1) * Input.GetAxis("Mouse Y") * sensitivity;
        transform.Rotate(Vector3.up, mouseX);
        transform.Rotate(Vector3.right, mouseY);
    }

    public void SetInvertYAxis(bool isInverted)
    {
        invertYAxis = isInverted;
    }
}

• The invertYAxis boolean controls the inversion of the Y-axis. The SetInvertYAxis method is used to update this value when the toggle changes.

Step 3: Connecting UI to Script

• Attach the CameraController script to the camera game object.
• In the Unity Editor, navigate to the Toggle component and assign its On Value Changed event to the SetInvertYAxis method of the script.
• This ensures that whenever the toggle’s state changes, the camera control logic updates accordingly.

Step 4: Saving User Preference

Persist user preference using PlayerPrefs:

public void SaveSettings()
{
    PlayerPrefs.SetInt("InvertYAxis", invertYAxis ? 1 : 0);
    PlayerPrefs.Save();
}

public void LoadSettings()
{
    invertYAxis = PlayerPrefs.GetInt("InvertYAxis", 0) == 1;
}

• Invoke SaveSettings when applying or exiting settings, and LoadSettings during initialization to restore preferences.

Conclusion

By following these steps, you can efficiently implement and manage camera inversion controls, providing a customizable experience for players. Remember to thoroughly test different scenarios to ensure robust functionality across various platforms.
