使用AS3中的補間類將對象移動到多個位置？

Question

您好我想作一個對象，在這種情況下，「ship_mc」，將3個不同的點在屏幕上，但我想使用Tween類。我不知道爲什麼它不工作，任何幫助將不勝感激。 我的代碼看起來像這樣

import fl.transitions.Tween; 
import fl.transitions.easing.*; 
import fl.transitions.TweenEvent; 

var myTween01:Tween = new Tween(this, "x", Regular.easeIn, 1416, 973, 4, true); 
var myTween02:Tween = new Tween(this, "y", Regular.easeIn, 206, 446, 4, true); 
var myTween03; 
var myTween04; 
var myTween05; 
var myTween06; 


myTween01.addEventListener(TweenEvent.MOTION_FINISH, onFinish); 
function onFinish(e:TweenEvent):void { 
myTween03:Tween = new Tween(this, "x", None.easeIn, 973, 695, 4, true); 
myTween04:Tween = new Tween(this, "y", None.easeIn, 446, 222, 4, true); 

} 

myTween04.addEventListener(TweenEvent.MOTION_FINISH, onFinish1); 
function onFinish1(e:TweenEvent):void { 
myTween05:Tween = new Tween(this, "x", None.easeIn, 695, 374, 4, true); 
myTween06:Tween = new Tween(this, "y", None.easeIn, 222, 239, 4, true); 
} 

，這是我得到

Symbol 'ship_mc', Layer 'Actions', Frame 1, Line 15 1067: Implicit coercion of a value of type fl.transitions:Tween to an unrelated type Class. 
Symbol 'ship_mc', Layer 'Actions', Frame 1, Line 15 1188: Illegal assignment to class Tween. 
Symbol 'ship_mc', Layer 'Actions', Frame 1, Line 16 1067: Implicit coercion of a value of type fl.transitions:Tween to an unrelated type Class.

Symbol 'ship_mc', Layer 'Actions', Frame 1, Line 22 1188: Illegal assignment to class Tween. 
Symbol 'ship_mc', Layer 'Actions', Frame 1, Line 23 1067: Implicit coercion of a value of type fl.transitions:Tween to an unrelated type Class. 
Symbol 'ship_mc', Layer 'Actions', Frame 1, Line 23 1188: Illegal assignment to class Tween. 

感謝錯誤，我知道人們會建議使用TweenLite的，但我想知道的問題是在這裏什麼，否則我不會學習！

Answer 1

的錯誤信息您收到告訴你問題出在哪裏存在的線路：15，16，22和23：

15: myTween03:Tween = new Tween(this, "x", None.easeIn, 973, 695, 4, true); 
16: myTween04:Tween = new Tween(this, "y", None.easeIn, 446, 222, 4, true); 

22: myTween05:Tween = new Tween(this, "x", None.easeIn, 695, 374, 4, true); 
23: myTween06:Tween = new Tween(this, "y", None.easeIn, 222, 239, 4, true); 

你的前兩個充斥代碼工作正常，所以什麼只是前兩者之間的區別，以及其他補間？你宣佈他們的方式。需要聲明myTween03，myTween04，myTween05和myTween06吐溫，以防止錯誤被拋出，因爲它認爲你正試圖初始化默認類爲吐溫否則。更改：

var myTween03; 
var myTween04; 
var myTween05; 
var myTween06; 

到

var myTween03:Tween; 
var myTween04:Tween; 
var myTween05:Tween; 
var myTween06:Tween; 

和初始化把你做的第一和第二吐溫的方式相同：

myTween03 = new Tween(this, "x", None.easeIn, 973, 695, 4, true); 
myTween04 = new Tween(this, "y", None.easeIn, 446, 222, 4, true); 

這基本上聲明變量視爲充斥着後來被初始化在代碼中，並將防止這些錯誤被拋出。
