How to access prefab's properties if i used Instantiate

[Andrea_D_Lebowski]

I’m using

GameObject temp = Instantiate(icon, new Vector3(x, y, 0), Quaternion.identity) as GameObject;

to instantiate my prefab ‘icon’, but now i wish to change the image element inside it

The prefab have this structure: TypeIcon (object with script) -> Canvas -> Type (the image)

now if i do myPrefab.something i can’t access his metods, but only GameObject’s options

You would just use .GetComponent<TYPE>() where TYPE is the component you want to access. For a game object with a spriter render attached this would be SpriteRender and for a UI object it would be Image I believe. From there you could directly talk about the sprite property.

Are you sure it’s the prefab you wish to change and not just the instantiated object? I’m not sure if you can edit prefabs directly at run time and even if you can I image it’s best to avoid doing so.

In your code snippet temp would reference the instantiated object. You’d want to add a public variable of type Sprite to the prefab code and attach the sprite you want to change to then you could change the sprite of it with

public Sprite newSprite;   //This is declared at the top
//Your other code here
     temp.GetComponent<SpriteRenderer>().sprite = newSprite;

Yes, my prefab has an array of sprites (from a spritesheet) and i want to be able to change the current sprite from this array

Lesson 86 covers this where you flick through sprite array positions via script. The basics of it are that you define a Sprite array which it sounds like you’ve already done

public Sprite[] hitSprites;

then you call the specific one you’re looking for

this.GetComponent<SpriteRenderer>().sprite = hitSprites[spriteIndex];

where spriteIndex is an int for the sprite you’re looking for in the array, remember an array starts at 0 so if you’ve got 4 sprites then it’s 0-3 to call each of them.

Hmm, i try and try but somethings don’t work.
The SpriteRender component take the right sprite, i see that on run, but i want that sprite to be on my component Image’s “Source Image”
Now im thinking that maybe my Image (called “Type”) need a script component to manage the Sprite image, but i dont recognize how. So if i do this i can search for the parent’s component SpriteRender and apply it.
I link the structure of my object:

obj Struct

Attached components:

topComps

inner Comp

My obj Class
public class TypeIcon : MonoBehaviour
{

public Sprite[] typesprites;

private string typeName;

Sprite icon;

//private void Start()
//{
//    Setting(typeName);
//}




public void Setting(string nam, int i)
{                       
    this.typeName = nam; print(typeName);
    this.GetComponentInChildren<SpriteRenderer>().sprite = typesprites[i];


}

The way i create the obj (Is a function inside windows canvas component):

public void PrintSingleType(Vector3 pos)
{
GameObject efficacia = Instantiate(typeIcon, pos, Quaternion.identity) as GameObject;
efficacia.transform.SetParent(transform);
efficacia.transform.position = pos;

    iconList.Add(efficacia);
}

Am i missing something?

[Martyn_Stewart]

If you’re using a UI image as opposed to a game object with a sprite renderer the component you wish to access is an Image instead of a SpriteRenderer so

GetComponent<Image>().sprite = typesprites[i];

You could also call the setting at the instantiate point so that you have efficacia.Setting("text",i); as opposed to doing it in the start method.

It worked after some panic!! Thank you! I can move on with the course now
