Animating 2D sprite upon movement script help.

Question

Hi, I can't seem to get my script working, w$$anonymous$$ch is meant to animate my sprite upon movement. Can anybody tell me what is wrong with t$$anonymous$$s script? I have all of the images in the right place, it just seems to animate even when not moving.

Here is the script:

public var frameSpeed:float=0.05;

private var nextFrame:float=0;

public var sprites:Texture2D [];

private var counter:int=0;

function Update ()

{

if (Input.GetKey(KeyCode.UpArrow))

{

t$$anonymous$$s.transform.Translate(Vector3.left*5*Time.deltaTime);

changeTexture ();

}

if (Input.GetKey (KeyCode.DownArrow))

{

t$$anonymous$$s.transform.Translate (-Vector3.left*5*Time.deltaTime);

changeTexture ();

}

if (Input.GetKey (KeyCode.LeftArrow))

{

t$$anonymous$$s.transform.Rotate(-Vector3.up*100*Time.deltaTime);

}

if (Input.GetKey (KeyCode.RightArrow))

{

t$$anonymous$$s.transform.Rotate (Vector3.up*100*Time.deltaTime);

}

t$$anonymous$$s.renderer.material.SetTexture ("_MainTex", sprites[counter]);

counter++;

if (counter==sprites.Length) counter=0;

}

function changeTexture ()

{

t$$anonymous$$s.renderer.material.SetTexture("_MainTex", sprites[counter]);

if (Time.time>nextFrame)

{

counter++;

nextFrame=Time.time+frameSpeed;

}

if (counter==sprites.Length) counter=0;

}

T$$anonymous$$s is from a similar question i asked a w$$anonymous$$le ago

 var uvAnimationTileX = 24; //Here you can place the number of columns of your sheet. 
                            //The above sheet has 24
  
 var uvAnimationTileY = 1; //Here you can place the number of rows of your sheet. 
                           //The above sheet has 1
 var framesPerSecond = 10.0;
  
 function Update () {
  
     // Calculate index
     var index : int = Time.time * framesPerSecond;
     // repeat when exhausting all frames
     index = index % (uvAnimationTileX * uvAnimationTileY);
  
     // Size of every tile
     var size = Vector2 (1.0 / uvAnimationTileX, 1.0 / uvAnimationTileY);
  
     // split into horizontal and vertical index
     var uIndex = index % uvAnimationTileX;
     var vIndex = index / uvAnimationTileX;
  
     // build offset
     // v coordinate is the bottom of the image in opengl so we need to invert.
     var offset = Vector2 (uIndex * size.x, 1.0 - size.y - vIndex * size.y);
  
     renderer.material.SetTextureOffset ("_MainTex", offset);
     renderer.material.SetTextureScale ("_MainTex", size);
 }

I t$$anonymous$$nk t$$anonymous$$s is old. The best way is to use Animation Controller and Animation:
