2D axis-aligned bounding box. [Rect2] consists of a position, a size, and several utility functions. It is typically used for fast overlap tests. It uses floating-point coordinates. The 3D counterpart to [Rect2] is [AABB]. https://docs.godotengine.org/en/3.4/tutorials/math/index.html https://docs.godotengine.org/en/3.4/tutorials/math/vector_math.html https://docs.godotengine.org/en/3.4/tutorials/math/vectors_advanced.html Constructs a [Rect2] by position and size. Constructs a [Rect2] by x, y, width, and height. Returns a [Rect2] 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 [Rect2] and b. Returns [code]true[/code] if this [Rect2] completely encloses another one. Returns this [Rect2] expanded to include a given point. Returns the area of the [Rect2]. Returns a copy of the [Rect2] grown a given amount of units towards all the sides. Returns a copy of the [Rect2] grown a given amount of units towards each direction individually. Returns a copy of the [Rect2] grown a given amount of units towards the [enum Margin] direction. Returns [code]true[/code] if the [Rect2] is flat or empty. Returns [code]true[/code] if the [Rect2] contains a point. Returns [code]true[/code] if the [Rect2] 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 [code]true[/code] if this [Rect2] and [code]rect[/code] are approximately equal, by calling [code]is_equal_approx[/code] on each component. Returns a larger [Rect2] that contains this [Rect2] 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.
