Changing clip used in animated sprite in a script

[mscowler]

I'm having trouble getting a script to change the clip used by an animated sprite. Here is my script.

#pragma strict

var myIndex:int;
var suit:GameObject[] = new GameObject[11];

function Start () {

suit[0] = transform.Find("CardSuit1").gameObject;
suit[1] = transform.Find("CardSuit2").gameObject;
suit[2] = transform.Find("CardSuit3").gameObject;
suit[3] = transform.Find("CardSuit4").gameObject;
suit[4] = transform.Find("CardSuit5").gameObject;
suit[5] = transform.Find("CardSuit6").gameObject;
suit[6] = transform.Find("CardSuit7").gameObject;
suit[7] = transform.Find("CardSuit8").gameObject;
suit[8] = transform.Find("CardSuit9").gameObject;
suit[9] = transform.Find("CardSuit10").gameObject;
suit[10] = transform.Find("CardSuit11").gameObject;

}

function Update () {

var i:int;
var j:int;
var k:int;

var sprite: tk2dSprite;
var animSprite : tk2dAnimatedSprite;

if (Global.cardValue[myIndex]==0) {

// Get next card in deck
Global.cardValue[myIndex] = Global.deckValue[Global.currentCardInDeck];
Global.cardSuit[myIndex] = Global.deckSuit[Global.currentCardInDeck];
Global.currentCardInDeck++;
i = Global.cardValue[myIndex];
k = Global.cardSuit[myIndex];

// Display card face with correct number
sprite = GetComponent(tk2dSprite);
if (i==1) sprite.SetSprite("card1");
if (i==2) sprite.SetSprite("card2");
if (i==3) sprite.SetSprite("card3");
if (i==4) sprite.SetSprite("card4");
if (i==5) sprite.SetSprite("card5");
if (i==6) sprite.SetSprite("card6");
if (i==7) sprite.SetSprite("card7");
if (i==8) sprite.SetSprite("card8");
if (i==9) sprite.SetSprite("card9");
if (i==10) sprite.SetSprite("cardM");

// Display animated suit characters
for (j=0; j<=10; j++) {
animSprite = suit[j].GetComponent(tk2dAnimatedSprite);
if(k==0) animSprite.Play("hatAnim");
if(k==1) animSprite.Play("frogAnim");
if(k==2) animSprite.Play("owlAnim");
if(k==3) animSprite.Play("dragonAnim");
}


The script is attached to a sprite called Card1 that has 11 children, CardSuit1-CardSuit11, that are sprites with animation. The animation attached to these sprites has 4 clips (hatAnim etc).

the code headed "// Display card face with correct number" works fine.

"suit" contains a gameObject list of the animated sprites (see the start function).

I know "suit" has been set up OK as I can activate/deactivate the animations using e.g. suit[j].SetActive(true);

The script compiles OK, but when I play the game I get the message "NullReferenceException:Object reference not set to an instance of an object" on whichever of the lines with "animSprite.Play" is executed.

Can anyone tell me what is wrong here?

Do those sprites actually have an animated sprite component on them? What can you see in the inspector?

[mscowler]

Yes they do. In fact if I comment out the problematic code and play the game, the sprites animate fine using the original clip, set in the inspector ("hatAnim").
If I change the default in the inspector to any of the other three clips, this also works.
Also, as I stated before, I can turn the sprites on and off in the script using "SetActive."
The sprites were created using "Create Other>tk2d>Sprite With Animator".

Ahaa. Now this makes sense.
I'm guessing you missed the migration 2D Toolkit 2.0 guide -
tk2dAnimatedSprite is now tk2dSpriteAnimator

Apart from the class change, it should just work.

That fixed it! Thanks for the help.
