Sprite animate on start ?

Questions & Answers

hi Guys i created a script which makes my sprite move, what i did is i created an texture array which hold my sprite images i know i should use a sprite sheet but i dont like it that way, anyways what i want to do is when Unity runs i want the sprite to run automatically. I want my array to cycle through the number of elements within the array and once it has reached to the end i want it to restart. I have created a function at the bottom and that's where i want the code written in and then i want to call it on the start function here is my script:

the array that hold the images is `var idleFrames : Texture [];`

var MoveSpeed : float =  5;

var CurrentFrame: int =0;

var altTerryTexture : Texture[];
var TerryIdleTexture: Texture [];

var idleFrames : Texture [];

function Start (){

     StartSpriteAnime();
}

function Update () {

     if (Input.GetKey(KeyCode.A)){

        transform.Translate(Vector3(MoveSpeed * Time.deltaTime, 0 ,0));
        renderer.material.mainTexture = altTerryTexture[CurrentFrame];

     }

     if (Input.GetKey(KeyCode.D)){

        transform.Translate(Vector3(-MoveSpeed * Time.deltaTime , 0, 0));
        renderer.material.mainTexture = TerryIdleTexture[CurrentFrame]; 

     }

}

function StartSpriteAnime(){
}

thanks in advance :)

You might be better off just including it in the update rather than making it a coroutine, not sure. If you include a "var spriteDelay:int;" for the time( in seconds) between sprite frames, you could do something similar to this (Javascript examples!):

call it like so:

var repeatTime : float = spriteDelay *idleFrames.length;
InvokeRepeating("StartSpriteAnime",0, repeatTime);

That should properly loop the sprite animation.

 function StartSpriteAnime(){

        for (tex in idleFrames){    

            renderer.material.mainTexture = tex;        
            yield.WaitForSeconds(spriteDelay);

        }
    }

Alternatively you could try using the mathf.repeat function:

function StartSpriteAnime(){

    while (playSpriteAnimation){    

        var timeOffset : float = Time.time / spriteDelay;
        var currentSprite : int = Mathf.Repeat(timeOffset, idleFrames.length-1);
        renderer.material.mainTexture = idleFrames[currentSprite];      
        yield;      
    }       

}

This second one involves a boolean "playSpriteAnimation" that you could set to false if needed to break the loop.
