Rectangle

A minimal rectangle with AABB collision and Arcade rendering support.

Note on coordinates: - The simulation/game logic uses a y-down coordinate system (origin top-left) to mirror the original project behavior. - Arcade renders in y-up space (origin bottom-left). We flip y at draw time.

Rectangle

Simple axis-aligned rectangle.

Attributes:

Name	Type	Description
pos_x	float	X coordinate of center in y-down space.
pos_y	float	Y coordinate of center in y-down space.

bottom: float property

center: tuple[float, float] property writable

center_x: float property

center_y: float property

color = BLACK instance-attribute

height = float(height) instance-attribute

left: float property

pos_x = float(left + width / 2) instance-attribute

pos_y = float(top + height / 2) instance-attribute

right: float property

top: float property

width = float(width) instance-attribute

__init__(left: float, top: float, width: float, height: float)

Initialize with a pygame-like signature: left, top, width, height.

Parameters:

Name	Type	Description	Default
left	float	Left edge X (y-down space).	required
top	float	Top edge Y (y-down space).	required
width	float	Rectangle width.	required
height	float	Rectangle height.	required

collide_rect(other: Rectangle) -> bool

Axis-aligned bounding-box collision with another rectangle (y-down space).

render_to(window_height: float) -> None

Draw as a filled rectangle using Arcade (convert y-down to y-up).

Parameters:

Name	Type	Description	Default
window_height	float	Current window height, used to flip y-axis for Arcade.	required

update_variables() -> None

Hook for subclasses that update position; kept for interface compatibility.
