		<method name="cast_motion">
			<return type="Array">

			<argument index="0" name="shape" type="Physics2DShapeQueryParameters">
			</argument>
			<description>
				Checks how far the shape can travel toward a point. Note that both the shape and the motion are supplied through a [Physics2DShapeQueryParameters] object. The method will return an array with two floats between 0 and 1, both representing a fraction of [code]motion[/code]. The first is how far the shape can move without triggering a collision, and the second is the point at which a collision will occur. If no collision is detected, the returned array will be [1, 1].
				If the shape can not move, the array will be empty ([code]dir.empty()==true[/code]).

			<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.

			<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. Note that 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.
				If the shape did not intersect anything, then an empty dictionary ([code]dir.empty()==true[/code]) is returned instead.

				Checks whether a point is inside any 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.
				Additionally, the method can take an array of objects or [RID]s that are to be excluded from collisions, or a bitmask representing the physics layers to check in.

				Intersects a ray in a given space. The returned object is a dictionary with the following fields:

				Checks the intersections of a shape, given through a [Physics2DShapeQueryParameters] object, against the space. Note that this method does not take into account the [code]motion[/code] property of the object. The intersected shapes are returned in an array containing dictionaries with the following fields:

				[code]shape[/code]: The shape index of the colliding shape.
				The number of intersections can be limited with the second parameter, to reduce the processing time.
