[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.

<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">

|
|

|
|

|
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.

<member name="end" type="Vector2i" setter="" getter="" default="Vector2i(0, 0)">

Ending corner. This is calculated as [code]position + size[/code]. Setting this value will change the size.

Size from [member position] to [member end]. Typically, all components are positive.
