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. https://docs.godotengine.org/en/latest/tutorials/math/index.html Constructs a [Rect2i] by position and size. Constructs a [Rect2i] by x, y, width, and height. Constructs a new [Rect2i] from [Rect2]. The floating point coordinates will be truncated. 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 the intersection of this [Rect2i] and b. 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 a given amount of units towards all the sides. Returns a copy of the [Rect2i] grown a given amount of units towards each direction individually. Returns a copy of the [Rect2i] grown a given amount of units towards the [enum Margin] direction. Returns [code]true[/code] if the [Rect2i] is flat or empty. Returns [code]true[/code] if the [Rect2i] contains a point. 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. Position (starting corner). Size from position to end.
