<brief_description>
2D axis-aligned bounding box.
</brief_description>
<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.
The 3D counterpart to [Rect2] is [AABB].

<method name="abs">
<return type="Rect2" />
2017-12-10 00:43:30 +01:00
<description>
Returns a [Rect2] with equivalent position and area, modified so that the top-left corner is the origin and [code]width[/code] and [code]height[/code] are positive.

</method>
<method name="clip">
<return type="Rect2" />
<argument index="0" name="b" type="Rect2" />
<description>
Returns the intersection of this [Rect2] and b.
</description>
</method>
<method name="encloses">
<return type="bool" />
<argument index="0" name="b" type="Rect2" />
<description>
Returns [code]true[/code] if this [Rect2] completely encloses another one.
</description>
</method>
<method name="expand">
<return type="Rect2" />
<argument index="0" name="to" type="Vector2" />
<description>
Returns a copy of this [Rect2] expanded to include a given point.
[b]Example:[/b]
[codeblock]
# position (-3, 2), size (1, 1)
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))
[/codeblock]
</description>
</method>
<method name="get_area">
<return type="float" />
<description>
Returns the area of the [Rect2].
</description>
</method>
<method name="grow">
<return type="Rect2" />
<argument index="0" name="by" type="float" />
<description>
Returns a copy of the [Rect2] grown a given amount of units towards all the sides.
</description>
</method>
<method name="grow_individual">
<return type="Rect2" />
<argument index="0" name="left" type="float" />
<argument index="1" name="top" type="float" />
<argument index="2" name="right" type="float" />
<argument index="3" name=" bottom" type="float" />
<description>
Returns a copy of the [Rect2] grown a given amount of units towards each direction individually.
</description>
</method>
<method name="grow_margin">
<return type="Rect2" />
<argument index="0" name="margin" type="int" />
<argument index="1" name="by" type="float" />
<description>
Returns a copy of the [Rect2] grown a given amount of units towards the [enum Margin] direction.
</description>
</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.
</description>
</method>
<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.

<method name="is_equal_approx">
<return type="bool" />
<argument index="0" name="rect" type="Rect2" />
2019-11-08 08:33:48 +01:00
<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.

</method>
<method name="merge">
<return type="Rect2" />
<argument index="0" name="b" type="Rect2" />
<description>
Returns a larger [Rect2] that contains this [Rect2] and [code]b[/code].
</description>
</method>
</methods>
<members>
<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.
</member>
<member name="position" type="Vector2" setter="" getter="" default="Vector2( 0, 0 )">
Beginning corner. Typically has values lower than [member end].
</member>
<member name="size" type="Vector2" setter="" getter="" default="Vector2( 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.
