Add Dynamic Texture2D

Dynamic Texture2D in UnityUI

Create Texture2D and assign image to it through a script

//需要在最上级Asset folder下建一个Resources folder，然后里面放要dynamic attach的texture

using UnityEngine;
using System.Collections;

public class TearApartControl : MonoBehaviour {
    public Texture2D handCursor;

    // Use this for initialization
    void Start () 
        {
        {
            handCursor = (Texture2D)Resources.Load("HandIcon");
        }
    
    }
