I'm starting out with xna, I'm pretty newbie with this, but I'm making my efforts to go on with this framework, anymay, my problem is: that I have many .png images and dont want to make an object for any of those images so I want to put them up in a Texture2D array, I thought that this is way to do it, but looks like it's not the correct way:

Texture2D[] _rCards, _bCards, _sCards;
_bCards = new Texture2D[9]; 
_rCards = new Texture2D[9];
_sCards = new Texture2D[6];

for (int i = 1; i < 10; i++)
{
    _bCards[i] = Content.Load<Texture2D>("Images/Common/Black/"+i);
    _rCards[i] = Content.Load<Texture2D>("Images/Common/Red/"+i);
    if(i<6)
        _sCards[i] = Content.Load<Texture2D>("Images/Special/Card" + (i-1));
}

The file names for the texture are 1.png, 2.png, 3.png, and so on.

For the special cards are card1.png, card2.png,card3.png and so on.

I'm trying to make a blackjack game.

Can you give me an advice to load all this textures in one single texture2D array.

The IDE gives an NULLREFERENCEEXCEPTION issue or something.

Maybe the language doesnt understands the entire adress to find the textures as a string.

  • Where is the NullReferenceException thrown? What object is null? Since you are trying to load PNGs, did you try adding +".png" to your strings? – Coincoin May 22 '12 at 15:56
  • Not sure if this is a copy paste thing, but in C# array indices start at 0 and go to Length-1. You index into _bCards and _rCards will hit an Out or Range Exception when i == 9. – borrillis May 22 '12 at 16:01

Indexes are 0 based...

for (int i = 1; i < 10; i++)
{
  _bCards[i-1] = Content.Load("Images/Common/Black/"+i);
  _rCards[i-1] = Content.Load("Images/Common/Red/"+i);
   if(i<6) _sCards[i-1] = Content.Load("Images/Special/Card" + (i-1));
}

if you want to load all textures at same time you can use the sprite sheet sample:

You will have an unique asset and a dictionary of source rectangles to draw the sprites...

  • But I'd have changed the indexes in the for loop and simply written `+(i+1)` in the texture names – Elideb May 23 '12 at 07:54
  • me too, but I was lazy, this way only needed three changes, ;P ... seriously, is the closest way to the original code.... – Blau May 23 '12 at 09:36
