|
[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.
|
|
Negative values for [member size] are not supported and will not work for most methods. Use [method abs] to get a Rect2i with a positive size.

|
|
<method name="has_no_area" qualifiers="const">
|

<return type="bool" />
|
|
<description>
|
|
Returns [code]true[/code] if the [Rect2i] is flat or empty, [code]false[/code] otherwise. See also [method get_area].
|
|
[b]Note:[/b] If the [Rect2i] has a negative size and is not flat or empty, [method has_no_area] will return [code]true[/code].

<method name="has_point" qualifiers="const">

<return type="bool" />
|
|
<argument index="0" name="point" type="Vector2i" />
|
|
<description>
|
|
Returns [code]true[/code] if the [Rect2i] contains a point. By convention, the right and bottom edges of the [Rect2i] are considered exclusive, so points on these edges are [b]not[/b] included.
|
|
[b]Note:[/b] This method is not reliable for [Rect2i] with a [i]negative size[/i]. Use [method abs] to get a positive sized equivalent rectangle to check for contained points.

<method name="intersection" qualifiers="const">
|

<argument index="0" name="b" type="Rect2i" />
|
|
<description>
|
|

|
|
<description>
|
|
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.
