3D Transformations

Rotate And Rotate Around

Instruction:
運用了Rotate以及RotateAround兩個Building Blocks使Statue可以自轉或繞著Rock公轉。

Building Blocks
(a) Set As Active Camera-Cameras/Montage/Set As Active Camera
(b) Text Display-Interface/Text/Text Display
(c) Switch On Key-Controllers/Keyboard/Switch On Key
(d) Per Second-Logics/Calculator/Per Second
(e) Rotate-Transformations/Basic/Rotate
(f) RotateAround-Transformations/Basic/RotateAround

製作構想
使物體發生自轉與公轉的效果可以運用Rotate以及RotateAround兩個Building Blocks,或再配合Building Blocks-Per Second即可。

製作步驟
(a) Camera

Set As Active Camera:設定現在使用的Camera。
Text Display:文字說明。
 
(b) Statue

Switch On Key:設定控制鍵分別為'1'、'2'。
Per Second:設定1秒鐘所旋轉的角度值X(Turn:圈數;Degree:角度),乘上一個Frame所花費時間,在pOut輸出旋轉角度值Y。
T X(pIn) * Elapsed Time = Y(pOut)
Rotate:於Angle of Rotation的pIn輸入旋轉角度值Y,設定Axis of Rotation-Y軸;設定Referential of the Axis-'-NULL-'或'Statue'皆可;勾選Hierarchy表示Building Blocks也同樣應用在Child(如圖示)。

Rotate Around:於Angle of Rotation的pIn輸入旋轉角度值Y,設定Axis of Rotation-Y軸;設定Referential of the Axis-'Rock'以及勾選Keep Orientation;勾選Hierarchy表示Building Blocks也同樣應用在Child(如圖示)。
