Assign different sprites to values in an array

Question

I am trying to assign different sprites into an array called sprites. I want each value of the array to hold a different spritesheet. Right now i am getting this error i dont understand why... :

 Cannot implicitly convert type `UnityEngine.Sprite[]' to `UnityEngine.Sprite'

In my public declaration i have:

 public static int MAIN_SPRITE = 1;
 public Sprite[] sprites;

further down in my void Start () i have:

 void Start () {
     sprites = new Sprite[32];
 }

and then i am trying to assign the spritesheet in my init() method like this:

 sprites[MAIN_SPRITE] = Resources.LoadAll<Sprite>("mainImg");

where mainImg is the name of my sprite sheet.

What am i doing wrong ? (The error appears for my last command where i set the array)

-Thanks

Hi Sandbird,

You are getting this because sprites[MAIN_SPRITRE] refers to a single sprite and not all the array, use this instead: sprites = Resources.LoadAll("mainImg") as Sprite[];

I've never used Resources.LoadAll but I think it returns an array, so you can not set a single element to it's returned array. I believe also that it returns an array of objects, so you will need to cast this object array to a sprite array using "as Sprite[]"

I hope that helps :)

If you have any questions, leave a comment and let me know if it works :)

 Resources.LoadAll<Sprite>("mainImg");

is already returning an array. Just assign it to the array directly without the indexer

i wont to populate the sprites array with many tiles which i'll use in code, For example:

 sprites[$$anonymous$$AIN_SPRITE] = Resources.LoadAll<Sprite>("mainImg");
 sprites[$$anonymous$$AIN_EXP] = Resources.LoadAll<Sprite>("explosions");
 ....

where $$anonymous$$AIN_SPRITE and $$anonymous$$AIN_EXP are gonna be integers co$$anonymous$$g from other scripts.

Then you'll need an array of Sprite arrays.

 public static int $$anonymous$$AIN_SPRITE = 1;
 public Sprite[][] sprites;
 
 void Start () {
    sprites = new Sprite[32][];
 }
 
 sprites[$$anonymous$$AIN_SPRITE] = Resources.LoadAll<Sprite>("mainImg");

Accessing one of them would be:

 sprites[$$anonymous$$AIN_SPRITE][0]

for example

I am co$$anonymous$$g from a PHP background and jagged array to mimic a normal array hurts my eyes.lol. Hmmm, so i guess even if the sprites object was a GameObject i wouldnt be able to save each tile in one value uh ? i have to trick it with jagged arrays ? I cant have an array with whatever i want inside for values ? Strings or Arrays ? example:

 sprites[0] = "a string";
 sprites[1] = "{array}";
 ....etc

thanks

You don’t have to trick anything. You can assign your sprites with values and call that up at specific times. If you want to start with a specific sprite you put it in the [0] and call that in the void Start. And then you can change it in a method afterwards.
