*Мой код *AS3

import com.greensock.*;
import com.greensock.easing.*;
 
 
TweenLite.to(mask_mc.c1, 41, {x:-700, y:-150, ease:Linear.easeNone});
TweenLite.to(mask_mc.c2, 39, {x:-700, y:10, ease:Linear.easeNone});
TweenLite.to(mask_mc.c3, 20, {x:-700, y:-15, ease:Linear.easeNone});
TweenLite.to(mask_mc.c4, 31, {x:-700, y:-140, ease:Linear.easeNone});
TweenLite.to(mask_mc.c5, 29, {x:-700, y:-20, ease:Linear.easeNone});
TweenLite.to(mask_mc.c6, 29, {x:-700, y:-130, ease:Linear.easeNone});
 
TweenLite.to(mask_mc.c7, 45, {x:-700, y:-100, ease:Linear.easeNone});
TweenLite.to(mask_mc.c8, 48, {x:-700, y:-180, ease:Linear.easeNone});
TweenLite.to(mask_mc.c9, 48, {x:-700, y:-40, ease:Linear.easeNone});
TweenLite.to(mask_mc.c10, 55, {x:-700, y:-80, ease:Linear.easeNone});
TweenLite.to(mask_mc.c11, 60, {x:-700, y:-130, ease:Linear.easeNone});
TweenLite.to(mask_mc.c12, 59, {x:-700, y:0, ease:Linear.easeNone});
 
TweenLite.to(mask_mc.c1a, 50, {x:300, y:-150, ease:Linear.easeNone});
TweenLite.to(mask_mc.c2a, 50, {x:260, y:10, ease:Linear.easeNone});
TweenLite.to(mask_mc.c3a, 50, {x:-300, y:-15, ease:Linear.easeNone});
TweenLite.to(mask_mc.c4a, 50, {x:50, y:-140, ease:Linear.easeNone});
TweenLite.to(mask_mc.c5a, 50, {x:-30, y:-20, ease:Linear.easeNone});
TweenLite.to(mask_mc.c6a, 50, {x:-170, y:-130, ease:Linear.easeNone});

Проблема в том что движение заканчивается а мне надо чтобы снова проигрывалось постоянно
спасибо заранее за вашу помощь
