語言版本: ActionScript 3.0
產品版本: Flash CS3
執行階段版本: Flash Player 9.0.28.0, AIR 1.0

FunctionEase 類別允許將自訂內插補點函數搭配 fl.motion 架構一起使用,以取代諸如 SimpleEase 和 CustomEase 的其他內插補點。fl.motion 架構包含 fl.motion.easing 套件中的數個加/減速函數。

getValue

()方法
public function getValue(time:Number, begin:Number, change:Number, duration:Number):Number

語言版本: ActionScript 3.0
產品版本: Flash CS3
執行階段版本: Flash Player 9.0.28.0, AIR 1.0

會使用指定的加/減速函數,計算動畫之數值屬性的內插補值。 如果已經預先設定 parameters 陣列,則除了 time、begin、change 和 duration 值之外,還會將這些值傳遞給加/減速函數。

參數

time:Number — 時間值,此值必須介於 0duration (含) 之間。 您可以選擇任何單位 (例如,影格、秒、毫秒),但是選擇的項目必須符合 duration 的單位。
 
begin:Number — 在補間動畫開始時 (此時 time 為 0) 的 animation 屬性值。
 
change:Number — animation 屬性值在補間動畫過程中發生的變更。 這個值可以是正值或負值。 例如,如果物件由 90 度旋轉到 60 度,則 change 為 -30。
 
duration:Number — 補間動畫的時間長度。 必須大於零。 您可以選擇任何單位 (例如,影格、秒、毫秒),但是選擇的項目必須符合 time 的單位。

傳回值
Number — 在指定時間的內插補值。

[ X ]為什麼顯示英文?
「ActionScript 3.0 參考」的內容是以英文顯示

並非所有「ActionScript 3.0 參考」的內容都翻譯為所有語言。當語言元素未翻譯時,就會以英文顯示。例如,ga.controls.HelpBox 類別並沒有翻譯為任何語言。因此在參考的繁體中文版本中,ga.controls.HelpBox 類別就會以英文顯示。
