We don't use that info for anything, and it generates unnecessary diffs every time we bump the minor version (and CI failures if we forget to sync some files from opt-in modules (mono, text_server_fb).

|
A 2D axis-aligned bounding box using floating-point coordinates.

<description>
|
|
[Rect2] consists of a position, a size, and several utility functions. It is typically used for fast overlap tests.
|
|
It uses floating-point coordinates. If you need integer coordinates, use [Rect2i] instead.
|
|
The 3D counterpart to [Rect2] is [AABB].
|
|
Negative values for [member size] are not supported and will not work for most methods. Use [method abs] to get a Rect2 with a positive size.

<return type="bool" />
|
|
<description>

|
<param index="0" name="point" type="Vector2" />
|
|
<description>
|
|
Returns [code]true[/code] if the [Rect2] contains a point. By convention, the right and bottom edges of the [Rect2] are considered exclusive, so points on these edges are [b]not[/b] included.
|
|
[b]Note:[/b] This method is not reliable for [Rect2] with a [i]negative size[/i]. Use [method abs] to get a positive sized equivalent rectangle to check for contained points.

<member name="end" type="Vector2" setter="" getter="" default="Vector2(0, 0)">

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.
