change scale and position

hey guys..
how do i get the sprite position and scale
and how do i change its position and scale?

for example:
when count[ 3 ] 
change position and scale of SpriteVisual mostesh

//@input Component.SpriteVisual mostesh

//@input Asset.Texture[] pics 

var count = 0;

script.mostesh.mainPass.baseTex = script.pics[0];

function onTapped(eventData) {

count++

if (count >= script.pics.length) {

count = 0;

}

script.mostesh.mainPass.baseTex = script.pics[count];

}

var event = script.createEvent("TapEvent");

event.bind(onTapped);

thank you for your help! ( :
