Notes：

Moveable represents any game object that has the ability to move about the gamespace. All Moveables have a T (transform) that describes their desired transform in game units, as well as a VT (Visible Transform) that eases to T over time. This allows for simplified movement where we only need to set T.x, T.y, etc. to their final position and the engine will ensure the Moveable VT eases to that final location, regardless of any events or timing.

Moveable 用于表示能够在游戏空间中移动的游戏对象。VT 会缓动到 T，不受事件和时间影响(例如一个新的弹出窗口出来，它会继续缓动到目标位置为止)。

Data Description Key Properties
T (Transform) Target or Final position x, y, w, h, r, scale
VT (Visual Transform) Current position x, y, w, h, r, scale
velocity Movement tracking x, y, r, scale, mag
role 减少冗余计算， Major 正常计算(每一帧重新计算)， Minor 在 Major 的基础上附加偏移 (offset)
alignment Relative positioning type, offset
parallax Visual depth effects shadow_parrallax, layered_parallax
pinch 捏挤压的效果 x = false, y = false

When you want to move an object, you simply set its target transform (T), and the system automatically:

  1. Calculates the velocity based on the difference between T and VT
  2. Updates the VT each frame based on this velocity
  3. Renders the object at the VT position
  4. Gradually eases VT toward T over time

This approach enables smooth, animation-like movement without requiring complex animation code for each object.
