[Rect2] consists of a position, a size, and several utility functions. It is typically used for fast overlap tests.
|
|
It uses floating-point coordinates.
|
|
The 3D counterpart to [Rect2] is [AABB].

|
|
var rect = Rect2(Vector2(-3, 2), Vector2(1, 1))
|
|
# position (-3, -1), size (3, 4), so we fit both rect and Vector2(0, -1)

|
var rect2 = rect.expand(Vector2(0, -1))

</method>
|
|
<method name="has_no_area">
|
|
<return type="bool" />
|
|
<description>
|
|
Returns [code]true[/code] if the [Rect2] is flat or empty.
|
|
</description>
|
|
</method>
|
|
<method name="has_point">
|
|
<return type="bool" />
|
|
<argument 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.

|
<method name="intersects">
|
|
<return type="bool" />
|
|
<argument index="0" name="b" type="Rect2" />
|
|
<argument index="1" name="include_borders" type="bool" default="false" />
|
|
<description>
|
|
Returns [code]true[/code] if the [Rect2] 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.

|
|
<description>
|
|
Returns [code]true[/code] if this [Rect2] and [code]rect[/code] are approximately equal, by calling [code]is_equal_approx[/code] on each component.
