Methods

clone

contains

  • contains(point: Vec2): boolean

  • Check whether the current rect contains the given point.

    Parameters

    • point: Vec2

      Specified point.

    Returns boolean

    The specified point is included in the rectangle and returns true', otherwise it returns false'.

containsRect

  • containsRect(other: Rect): boolean

  • Returns true if the other rect entirely inside this rectangle.

    Parameters

    • other: Rect

      Specified rectangles.

    Returns boolean

    Returns true' if all the points of the specified rectangle are included in the current rectangle, false' otherwise.

equals

  • Check whether the current Rect equals another one.

    Parameters

    • other: Rect

      Specified rectangles.

    Returns boolean

    Returns true' when the minimum and maximum values of both rectangles are equal, respectively; otherwise, returns false'.
