Methods

Get Rect

get_rect() → Rect

Get the axis-aligned bounding rectangle of the polygon.

Returns

Rect : The bounding rectangle.

Copy

copy() → Polygon

Return a copy of the polygon.

Returns

Polygon : A new polygon with the same points.

Rotate

rotate(angle: float, pivot: Vec2 = ...) → None

Rotate the polygon around a pivot point.

Args

  • angle : The rotation angle in radians.
  • pivot : The normalized point relative to the polygon's bounding box to rotate around. Defaults to center (0.5, 0.5).

Translate

translate(offset: Vec2) → None

Move the polygon by an offset.

Args

  • offset : The offset to move by.

Scale

scale(factor: float, pivot: Vec2 = ...) → None

Scale the polygon uniformly from a pivot point.

Args

  • factor : The scaling factor.
  • pivot : The normalized point relative to the polygon's bounding box to scale from. Defaults to center (0.5, 0.5).
scale(factor: Vec2, pivot: Vec2 = ...) → None

Scale the polygon non-uniformly from a pivot point.

Args

  • factor : The scaling factors for x and y.
  • pivot : The normalized point relative to the polygon's bounding box to scale from. Defaults to center (0.5, 0.5).
