<brief_description >
2D axis-aligned bounding box using integer coordinates.
</brief_description>
<description >
[Rect2i] consists of a position, a size, and several utility functions. It is typically used for fast overlap tests.
2020-09-21 20:27:50 +08:00
It uses integer coordinates. If you need floating-point coordinates, use [Rect2] instead.
2020-04-06 16:34:18 +08:00
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.

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.

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.

Ending corner. This is calculated as [code]position + size[/code]. Setting this value will change the size.
</member>
<member name= "position" type= "Vector2i" setter= "" getter= "" default= "Vector2i(0, 0)" >
Beginning corner. Typically has values lower than [member end].

<member name= "size" type= "Vector2i" setter= "" getter= "" default= "Vector2i(0, 0)" >
Size from [member position] to [member end]. Typically, all components are positive.
If the size is negative, you can use [method abs] to fix it.
