	<methods>
		<method name="cast_motion">
			<return type="Array" />
			<argument index="0" name="shape" type="Physics2DShapeQueryParameters" />
			<description>
				Checks how far a [Shape2D] can move without colliding. All the parameters for the query, including the shape and the motion, are supplied through a [Physics2DShapeQueryParameters] object.
				Returns an array with the safe and unsafe proportions (between 0 and 1) of the motion. The safe proportion is the maximum fraction of the motion that can be made without a collision. The unsafe proportion is the minimum fraction of the distance that must be moved for a collision. If no collision is detected a result of [code][1.0, 1.0][/code] will be returned.
				[b]Note:[/b] Any [Shape2D]s that the shape is already colliding with e.g. inside of, will be ignored. Use [method collide_shape] to determine the [Shape2D]s that the shape is already colliding with.

		<method name="collide_shape">
			<return type="Array" />
			<argument index="0" name="shape" type="Physics2DShapeQueryParameters" />
			<argument index="1" name="max_results" type="int" default="32" />
			<description>
				Checks the intersections of a shape, given through a [Physics2DShapeQueryParameters] object, against the space. The resulting array contains a list of points where the shape intersects another. Like with [method intersect_shape], the number of returned results can be limited to save processing time.

		<method name="get_rest_info">
			<return type="Dictionary" />
			<argument index="0" name="shape" type="Physics2DShapeQueryParameters" />
			<description>
				Checks the intersections of a shape, given through a [Physics2DShapeQueryParameters] object, against the space. If it collides with more than one shape, the nearest one is selected. If the shape did not intersect anything, then an empty dictionary is returned instead.
				[b]Note:[/b] This method does not take into account the [code]motion[/code] property of the object. The returned object is a dictionary containing the following fields:
				[code]collider_id[/code]: The colliding object's ID.
				[code]linear_velocity[/code]: The colliding object's velocity [Vector2]. If the object is an [Area2D], the result is [code](0, 0)[/code].
				[code]metadata[/code]: The intersecting shape's metadata. This metadata is different from [method Object.get_meta], and is set with [method Physics2DServer.shape_set_data].
				[code]normal[/code]: The object's surface normal at the intersection point.
				[code]point[/code]: The intersection point.
				[code]rid[/code]: The intersecting object's [RID].
				[code]shape[/code]: The shape index of the colliding shape.

				Checks whether a point is inside any solid shape. The shapes the point is inside of are returned in an array containing dictionaries with the following fields:
				[code]collider[/code]: The colliding object.
				[code]collider_id[/code]: The colliding object's ID.
				[code]metadata[/code]: The intersecting shape's metadata. This metadata is different from [method Object.get_meta], and is set with [method Physics2DServer.shape_set_data].
				[code]rid[/code]: The intersecting object's [RID].
				[code]shape[/code]: The shape index of the colliding shape.
				The number of intersections can be limited with the [code]max_results[/code] parameter, to reduce the processing time.
				Additionally, the method can take an [code]exclude[/code] array of objects or [RID]s that are to be excluded from collisions, a [code]collision_mask[/code] bitmask representing the physics layers to check in, or booleans to determine if the ray should collide with [PhysicsBody2D]s or [Area2D]s, respectively.
				[b]Note:[/b] [ConcavePolygonShape2D]s and [CollisionPolygon2D]s in [code]Segments[/code] build mode are not solid shapes. Therefore, they will not be detected.
