Screenshot capture from mobile

Unity Engine
1

I want to take screen shot within gameplay in mobile and then share it.

I have done this with CaptureScreenShot but it captures complete screen, i want only specific area i.e smaller panel only that comes after game to show score.

Plz help me out.

To save a part of the screen in a Texture2D you can use the function Texture2D.ReadPixels after assigning to your camera a targetTexture and setting this targetTexture as active.

Here the code :

using UnityEngine;
using System.Collections;
using EasyEditor;

public class TakeScreenShot : MonoBehaviour {

    public Material aMaterial;

    public int height = 100;
    public int width = 100;
   
    [Inspector]
    void TakeScreenshot()
    {
        Camera camera = GetComponent<Camera>();

        RenderTexture cameraOutputTexture = new RenderTexture(camera.pixelWidth, camera.pixelHeight, 0);
        camera.targetTexture = cameraOutputTexture;

        RenderTexture currentActiveRT = RenderTexture.active;
        RenderTexture.active = cameraOutputTexture;

        camera.Render();
        Texture2D texture2D = new Texture2D(width, height, TextureFormat.RGB24, false);

        texture2D.ReadPixels(new Rect(0, 0, width, height), 0, 0);
        texture2D.Apply();

        RenderTexture.active = currentActiveRT;
       
        aMaterial.mainTexture = texture2D;
        camera.targetTexture = null;
    }
}
