	<brief_description>
		A 2D axis-aligned bounding box using floating-point coordinates.
	</brief_description>
	<description>
		The [Rect2] built-in [Variant] type represents an axis-aligned rectangle in a 2D space. It is defined by its [member position] and [member size], which are [Vector2]. It is frequently used for fast overlap tests (see [method intersects]). Although [Rect2] itself is axis-aligned, it can be combined with [Transform2D] to represent a rotated or skewed rectangle.
		For integer coordinates, use [Rect2i]. The 3D equivalent to [Rect2] is [AABB].
		[b]Note:[/b] Negative values for [member size] are not supported. With negative size, most [Rect2] methods do not work correctly. Use [method abs] to get an equivalent [Rect2] with a non-negative size.
		[b]Note:[/b] In a boolean context, a [Rect2] evaluates to [code]false[/code] if both [member position] and [member size] are zero (equal to [constant Vector2.ZERO]). Otherwise, it always evaluates to [code]true[/code].

	<methods>
		<method name="abs" qualifiers="const">
			<return type="Rect2" />
			<description>
				Returns a [Rect2] equivalent to this rectangle, with its width and height modified to be non-negative values, and with its [member position] being the top-left corner of the rectangle.
				[codeblocks]
				[gdscript]
				var rect = Rect2(25, 25, -100, -50)
				var absolute = rect.abs() # absolute is Rect2(-75, -25, 100, 50)
				[/gdscript]
				[csharp]
				var rect = new Rect2(25, 25, -100, -50);
				var absolute = rect.Abs(); // absolute is Rect2(-75, -25, 100, 50)
				[/csharp]
				[/codeblocks]
				[b]Note:[/b] It's recommended to use this method when [member size] is negative, as most other methods in Godot assume that the [member position] is the top-left corner, and the [member end] is the bottom-right corner.

	</methods>
	<members>
		<member name="end" type="Vector2" setter="" getter="" default="Vector2(0, 0)">
			The ending point. This is usually the bottom-right corner of the rectangle, and is equivalent to [code]position + size[/code]. Setting this point affects the [member size].
		</member>
		<member name="position" type="Vector2" setter="" getter="" default="Vector2(0, 0)">
			The origin point. This is usually the top-left corner of the rectangle.
		</member>
		<member name="size" type="Vector2" setter="" getter="" default="Vector2(0, 0)">
			The rectangle's width and height, starting from [member position]. Setting this value also affects the [member end] point.
			[b]Note:[/b] It's recommended setting the width and height to non-negative values, as most methods in Godot assume that the [member position] is the top-left corner, and the [member end] is the bottom-right corner. To get an equivalent rectangle with non-negative size, use [method abs].

	<operators>
		<operator name="operator !=">
			<return type="bool" />
			<param index="0" name="right" type="Rect2" />
			<description>
				Returns [code]true[/code] if the [member position] or [member size] of both rectangles are not equal.
				[b]Note:[/b] Due to floating-point precision errors, consider using [method is_equal_approx] instead, which is more reliable.
			</description>
		</operator>
		<operator name="operator *">
			<return type="Rect2" />
			<param index="0" name="right" type="Transform2D" />
			<description>
				Inversely transforms (multiplies) the [Rect2] by the given [Transform2D] transformation matrix, under the assumption that the transformation basis is orthonormal (i.e. rotation/reflection is fine, scaling/skew is not).
				[code]rect * transform[/code] is equivalent to [code]transform.inverse() * rect[/code]. See [method Transform2D.inverse].
				For transforming by inverse of an affine transformation (e.g. with scaling) [code]transform.affine_inverse() * rect[/code] can be used instead. See [method Transform2D.affine_inverse].
			</description>
		</operator>
		<operator name="operator ==">
			<return type="bool" />
			<param index="0" name="right" type="Rect2" />
			<description>
				Returns [code]true[/code] if both [member position] and [member size] of the rectangles are exactly equal, respectively.
				[b]Note:[/b] Due to floating-point precision errors, consider using [method is_equal_approx] instead, which is more reliable.
