Instance Methods

#initialize

Create a new Rect with optional position and dimensions.

Parameters:

Name	Type	Description
x	Float	The x position (default: 0)
y	Float	The y position (default: 0)
w	Float	The width (default: 0)
h	Float	The height (default: 0)

Returns: Rect - The new rectangle

Example:

Rect.new(10, 20, 100, 50)   # x=10, y=20, w=100, h=50

---

#x

Get the x position (left edge).

Returns: Float - The x position

Example:

x = rect.x

---

#y

Get the y position (top edge).

Returns: Float - The y position

Example:

y = rect.y

---

#w

Get the width.

Returns: Float - The width

Example:

width = rect.w

---

#h

Get the height.

Returns: Float - The height

Example:

height = rect.h

---

#to_s

Common math utility functions for game development. Provides lerp, clamp, smoothstep, and other interpolation helpers. Named "Mathf" to avoid conflict with Ruby's built-in Math module.

Returns: String - String in format "Rect(x, y, w, h)"

Example:

# Smooth transitions
  t = elapsed / duration
  alpha = Mathf.smoothstep(0, 1, t) * 255
