2D Axis-aligned bounding box. Rect2 consists of a position, a size, and several utility functions. It is typically used for fast overlap tests. http://docs.godotengine.org/en/3.0/learning/features/math/index.html Constructs a [code]Rect2[/code] by position and size. Constructs a [code]Rect2[/code] by x, y, width, and height. Returns the intersection of this [code]Rect2[/code] and b. Returns [code]true[/code] if this [code]Rect2[/code] completely encloses another one. Returns this [code]Rect2[/code] expanded to include a given point. Returns the area of the [code]Rect2[/code]. Returns a copy of the [code]Rect2[/code] grown a given amount of units towards all the sides. Returns a copy of the [code]Rect2[/code] grown a given amount of units towards each direction individually. Returns a copy of the [code]Rect2[/code] grown a given amount of units towards the [Margin] direction. Returns [code]true[/code] if the [code]Rect2[/code] is flat or empty. Returns [code]true[/code] if the [code]Rect2[/code] contains a point. Returns [code]true[/code] if the [code]Rect2[/code] overlaps with another. Returns a larger Rect2 that contains this Rect2 and [code]with[/code]. Ending corner. Position (starting corner). Size from position to end.
