Share button AR
Hi guys, i'm a complete noob in Unity and have no programming knowledge. Nevertheless i did an AR app with Unity and Vuforia that for now is working. I found a C# script to take a screenshot of the screen and call the default Android sharing options. I'm now trying to implement that script into a Button but the script calls for a GUITexture. I had it working with the GUITexture but i'd want it to worrk with the button. So here's the script, what needs to change for it to work with the onClick() event of the button?
using UnityEngine;
using System.Collections;
using System.IO;
public class Share : MonoBehaviour {
