Update score animation

Draw the "+Number" text over your score and move it up each frame. Reduce the alpha value each frame as well and it will have a fading effect just like that. Remove or reset it once it becomes invisible.

I made it. Codes are belowed.

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class AnimateText : MonoBehaviour
 {
 
         public Text txt;
         public float moveSpeed = 100.0f;
         public float alphaValue = 1.0f;
 
 
         // Use this for initialization
         void Start ()
         {
 
         }
     
         // Update is called once per frame
         void Update ()
         {
 
                 if (alphaValue <= 0.0f) {
                         txt.transform.Translate (new Vector2 (0, 0));
                         txt.enabled = false;
                         
                 } else {
                         txt.transform.Translate (new Vector2 (0, moveSpeed) * Time.deltaTime);
             
                         alphaValue -= Time.deltaTime;
             
                         txt.color = new Color (1.0f, 1.0f, 1.0f, alphaValue);    
                 }
     
         }
 
         public void Exit ()
         {
                 Application.Quit ();
         }
 
         public void Restart(){
         Application.LoadLevel (0);
     }
 }
