Need help fixing my Anime Keys

Unity Engine
1

This is my Players Controls

var speed = 10.0;
function Update () {
var x = Input.GetAxis(“Horizontal”) * Time.deltaTime * speed;
var y = Input.GetAxis(“Vertical”) * Time.deltaTime * speed;
transform.Translate(x, y, 0);
}

and this is my Players Anime

function Update ()
{
if (Input.GetKeyDown (“w”))
animation.Play (“Up”);
}

This is a 2D Platform, my issue is my Players Plane when i push up, the model pops back to its starting local point, 0,0,0. after this is fixed,can some one point me towards how to link and blend, my anime clips together, each movement has 3 clips,
id like when u push up the plane titls upwards, then if i hold it, it keeps its up tilt locked, then when released , it tilts back to Idle clip.
