Resources.Load sprite returning null (4.3)

Question

Evening all,

I am attempting to programmatically populate my scene based on data in an XML file. I have parsed and created an object model from the XML no problem.

Now I am trying to create and add sprites to the scene. The sprite already exists within my assets folder.

I am doing the following where item.name matches the name of my sprite in unity.

                 var gameObject = (GameObject)Resources.Load(item.Name) as GameObject;
 
                 if(gameObject == null) Debug.LogError("item GameObject is null");
 
                 Instantiate(gameObject, new Vector3((float)item.UnityPositionX, (float)item.UnityPositionY, layer.Depth), new Quaternion(0,0,0,0));

However gameObject is always null.

Any suggestions or pointers would be much appreciated.

Thanks

Edit -

Through trial and error I got the following code to programmatic ally put a new 2d sprite type into the scene at runtime.

         var gameObject = new GameObject ();
         gameObject.transform.position = new Vector3 (0, 0, 0);
 
         gameObject.AddComponent ("SpriteRenderer");
 
         var renderer = (SpriteRenderer)gameObject.GetComponent ("SpriteRenderer");
 
         renderer.sprite = Resources.Load<Sprite>("Grass50x50");

OK, I have got the sprite object loading in correctly. I can only assume some of the examples out there are old and the objects dont work the way they once did.

The following loads a sprite from resources just fine.

 var sprite = Resources.Load<Sprite>("Grass50x50");

Now the next stage is to use that to build up, in code a 2D sprite based game object in the same way it would be created using the Unity editor.

This works only for a single sprite that's the whole texture file; it doesn't work when you have a sprite sheet with a bunch of sprites defined. In that case you have to use LoadAll (with the path to the sprite sheet) to get all the sprites at once, and then inspect the resulting array to find what you need.

Neat! To assign the loaded sprite you can also use this ( for Image):

     .GetComponent<Image>().overrideSprite = //Your sprite

I'm pretty sure that if you use .sprite ins$$anonymous$$d you won't get the job done

public Image myImage;

myImage.sprite = (Sprite) Resources.Load("YourFolderName/YourSpriteName",typeof(Sprite));

For me works next two lines of code:

SpriteRenderer renderer = gameObject.GetComponent();

renderer.sprite = Resources.Load("YourFolderName/YourSpriteName");

Need to write full path to Resources folder. All files need which you need to use must be stored in resources folder:)

Your comment help me a lot

thanks

Resources.Load are searching in the directory "Assets/Resources" That's why you need to do

 _sprites = Resources.LoadAll<Sprite>(spritesPath);

or

 _sprites = Resources.Load<Sprite>(spritesPath);

with spritesPath as relative path. If you need to load all from folder "Assets/Resources/Sprites", you need to write only "Sprites".

after this you can just do the following:

 var sprite = sprites[0];

or

 var sprite = _sprites.Where(a => a.name == "Sprite_Name_Needed").First();
