2D axis-aligned bounding box using integer coordinates. [Rect2i] consists of a position, a size, and several utility functions. It is typically used for fast overlap tests. It uses integer coordinates. If you need floating-point coordinates, use [Rect2] instead. https://docs.godotengine.org/en/latest/tutorials/math/index.html https://docs.godotengine.org/en/latest/tutorials/math/vector_math.html Constructs a default-initialized [Rect2i] with default (zero) values of [member position] and [member size]. Constructs a [Rect2i] as a copy of the given [Rect2i]. Constructs a new [Rect2i] from [Rect2]. The floating point coordinates will be truncated. Constructs a [Rect2i] by position and size. Constructs a [Rect2i] by x, y, width, and height. Returns a [Rect2i] with equivalent position and area, modified so that the top-left corner is the origin and [code]width[/code] and [code]height[/code] are positive. Returns [code]true[/code] if this [Rect2i] completely encloses another one. Returns this [Rect2i] expanded to include a given point. Returns the area of the [Rect2i]. Returns a copy of the [Rect2i] grown by the specified [code]amount[/code] on all sides. Returns a copy of the [Rect2i] grown by the specified amount on each side individually. Returns a copy of the [Rect2i] grown by the specified [code]amount[/code] on the specified [enum Side]. Returns [code]true[/code] if the [Rect2i] is flat or empty. Returns [code]true[/code] if the [Rect2i] contains a point. Returns the intersection of this [Rect2i] and [code]b[/code]. If the rectangles do not intersect, an empty [Rect2i] is returned. Returns [code]true[/code] if the [Rect2i] overlaps with [code]b[/code] (i.e. they have at least one point in common). If [code]include_borders[/code] is [code]true[/code], they will also be considered overlapping if their borders touch, even without intersection. Returns a larger [Rect2i] that contains this [Rect2i] and [code]b[/code]. Ending corner. This is calculated as [code]position + size[/code]. Setting this value will change the size. Beginning corner. Typically has values lower than [member end]. Size from [member position] to [member end]. Typically, all components are positive. If the size is negative, you can use [method abs] to fix it.
