Question by mkobaner · Feb 28, 2016 at 03:40 PM · c#spriterenderer

Changing sprite of a button with New ui system via code c#

Hello,

I am trying to make a button's sprite change if the condition is met, i tried two methods one is this:

using UnityEngine; using System.Collections; using UnityEngine.UI; public class Unlock : MonoBehaviour {

 public Button currentButton;

 public Sprite newSprite;
 void Start () {
     if(PlayerPrefs.GetInt("Level")< 2)
     {
         currentButton.interactable = true;
         GetComponent(SpriteRenderer).sprite = newSprite;
         }
 }
 }


i get error Assets/Scripts/Unlock.cs(13,38): error CS0119: Expression denotes a type', where a variable', value' or method group' was expected

and the other one is this ( in this method there are no errors but i cant show renderer in menu)

using UnityEngine; using System.Collections; using UnityEngine.UI; public class Unlock : MonoBehaviour {

 public Button currentButton;

 public Sprite newSprite;
 public SpriteRenderer curSpriteRenderer;
 void Start () {
     if(PlayerPrefs.GetInt("Level")< 2)
     {
         currentButton.interactable = true;
         curSpriteRenderer.sprite = newSprite;
         }
 }
 }

any help is very appreciated.
