Trouble using GetComponent<Image> in parent class of a button prefab.

I wasn't expecting this. Here is my code:

Code (CSharp):

1.  
2.         int x = 50;
3.         int count = 0;
4.         foreach(Sprite thisSprite in GameTileSprites)
5.         {              
6.             TextureButton newButton = Instantiate(TextureButton, new Vector3(x, 68.8f, 0), Quaternion.identity) as TextureButton;
7.             Image buttonImage = newButton.transform.GetComponent<Image>();
8.             buttonImage.sprite = thisSprite;
9.             newButton.transform.SetParent(panelTextureImages);
10.             newButton.ElementIndex = count;
11.             x += 90;
12.             count += 1;
13.         }

If I instantiate as TextureButton, then I cannot obtain the Image component from the Button subclass. If I instantiate as a Button, then I cannot access the ElementIndex property of the superclass. I was under the impression that GetComponent would obtain any component within the complete gameobject. Tips? Solutions?

 

Did you make sure to add a reference to the UnityEngine.UI?

using UnityEngine.UI;

 

While I had that problem about a week ago that is unfortunately not the solution to this problem. Thanks for the response though.

 

Maybe try parenting your object to a canvas before you try getting the image component? Btw, not related, but the following code:

Code (CSharp):

1. newButton.transform.GetComponent<Image>();

can simply be:

Code (CSharp):

1. newButton.GetComponent<Image>();

No need to dig into transform first. You can get any component from any component.

 

Thanks again for your responses. I ended up solving it with the following code:

Code (CSharp):

1. void DisplayGameTileTextures()
2.     {
3.         int x = 50;
4.         int count = 0;
5.         foreach(Sprite thisSprite in GameTileSprites)
6.         {      
7.             TextureButton newTextureButton = Instantiate(NewTextureButton, new Vector3(x, 68.8f, 0), Quaternion.identity) as TextureButton;
8.             newTextureButton.ElementIndex = count;
9.             newTextureButton.transform.SetParent(panelTextureImages);
10.             TextureButtons.Add(newTextureButton);
11.  
12.             Image buttonImage = newTextureButton.gameObject.GetComponent<Image>();
13.             buttonImage.sprite = thisSprite;
14.  
15.             x += 90;
16.             count += 1;
17.         }
18.     }
