<brief_description>
A 2D axis-aligned bounding box using integer coordinates.
</brief_description>
<description>
The [Rect2i] built-in [Variant] type represents an axis-aligned rectangle in a 2D space, using integer coordinates. It is defined by its [member position] and [member size], which are [Vector2i]. Because it does not rotate, it is frequently used for fast overlap tests (see [method intersects]).
For floating-point coordinates, see [Rect2].
[b]Note:[/b] Negative values for [member size] are not supported. With negative size, most [Rect2i] methods do not work correctly. Use [method abs] to get an equivalent [Rect2i] with a non-negative size.
[b]Note:[/b] In a boolean context, a [Rect2i] evaluates to [code]false[/code] if both [member position] and [member size] are zero (equal to [constant Vector2i.ZERO]). Otherwise, it always evaluates to [code]true[/code].

<return type="Rect2i" />
<param index="0" name="x" type="int" />
<param index="1" name="y" type="int" />
<param index="2" name="width" type="int" />

<methods>
<method name="abs" qualifiers="const">
<return type="Rect2i" />
<description>
Returns a [Rect2i] 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 = Rect2i(25, 25, -100, -50)
var absolute = rect.abs() # absolute is Rect2i(-75, -25, 100, 50)
[/gdscript]
[csharp]
var rect = new Rect2I(25, 25, -100, -50);
var absolute = rect.Abs(); // absolute is Rect2I(-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.
</description>
</method>

<return type="bool" />
<param index="0" name="b" type="Rect2i" />

<return type="Vector2i" />
<description>

<method name="grow" qualifiers="const">
<return type="Rect2i" />
<param index="0" name="amount" type="int" />
<description>
Returns a copy of this rectangle extended on all sides by the given [param amount]. A negative [param amount] shrinks the rectangle instead. See also [method grow_individual] and [method grow_side].

</method>
<method name="has_area" qualifiers="const">
<return type="bool" />
<description>

<return type="bool" />
<param index="0" name="point" type="Vector2i" />
<description>
Returns [code]true[/code] if the rectangle contains the given [param point]. By convention, points on the right and bottom edges are [b]not[/b] included.
[b]Note:[/b] This method is not reliable for [Rect2i] with a [i]negative[/i] [member size]. Use [method abs] first to get a valid rectangle.
</description>
</method>
<method name="intersection" qualifiers="const">
<return type="Rect2i" />
<param index="0" name="b" type="Rect2i" />
<description>
Returns the intersection between this rectangle and [param b]. If the rectangles do not intersect, returns an empty [Rect2i].
[codeblocks]
[gdscript]
var a = Rect2i(0, 0, 5, 10)
var b = Rect2i(2, 0, 8, 4)
var c = a.intersection(b) # c is Rect2i(2, 0, 3, 4)
[/gdscript]
[csharp]
var a = new Rect2I(0, 0, 5, 10);
var b = new Rect2I(2, 0, 8, 4);
var c = rect1.Intersection(rect2); // c is Rect2I(2, 0, 3, 4)
[/csharp]
[/codeblocks]
[b]Note:[/b] If you only need to know whether two rectangles are overlapping, use [method intersects], instead.
</description>
</method>
<method name="intersects" qualifiers="const">
<return type="bool" />
<param index="0" name="b" type="Rect2i" />
<description>
Returns [code]true[/code] if this rectangle overlaps with the [param b] rectangle. The edges of both rectangles are excluded.

</method>
<method name="merge" qualifiers="const">
<return type="Rect2i" />
<param index="0" name="b" type="Rect2i" />
<description>
Returns a [Rect2i] that encloses both this rectangle and [param b] around the edges. See also [method encloses].
</description>
</method>
</methods>
<members>
<member name="end" type="Vector2i" setter="" getter="" default="Vector2i(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="Vector2i" setter="" getter="" default="Vector2i(0, 0)">
The origin point. This is usually the top-left corner of the rectangle.
</member>
<member name="size" type="Vector2i" setter="" getter="" default="Vector2i(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].
