📐 RetroPy `v2d` Module Documentation (MicroPython)

The v2d module provides a lightweight 2D vector type used throughout the RetroPy engine. It encapsulates x and y floating-point coordinates and supports basic attribute access and printing.

📦 Class: `v2d`

🔧 Constructor

v2d(x, y)

x: float – X-coordinate
y: float – Y-coordinate

Creates a new 2D vector with the given coordinates.

📄 String Representation

`str(v)`

Returns a string representation in the format:

v2d(x.xx, y.yy)

Used for debugging and printing vectors.

🔍 Attributes

v.x: Get or set the x-coordinate (float)
v.y: Get or set the y-coordinate (float)

Example:

p = v2d(3.5, 1.2)
print(p.x)       # 3.5
p.y = 9.0

📌 Notes

The v2d type is registered as a MicroPython module and can be imported using import v2d.
It uses MP_TYPE_FLAG_HAS_SPECIAL_ACCESSORS to enable custom attribute access logic.
