Multiple Sprite animations

So I am wondering how I would implement a sprite sheet with multiple animations on it. Sofar I have this script that just goes from one offset to the other 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); } The problem now is that I would like to make it so that I can have one row be one animation and the next row could be another animation so I could animate a sheet like this

so I would really appreciate the help if someone would tell me how to do this. Thanks in advance.
