<description>
Check whether the shape can travel to a point. If it can, the method will return an array with two floats: The first is the distance the shape can move in that direction without colliding, and the second is the distance at which it will collide.
If the shape can not move, the array will be empty.
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]).

Check the intersections of a shape, given through a [Physics2DShapeQueryParameters] object, against the space. If it collides with more than a shape, the nearest one is selected. The returned object is a dictionary containing the following fields:
pointo: Place where the shapes intersect.
normal: Normal of the object at the point where the shapes intersect.
shape: Shape index within the object against which the shape intersected.
metadata: Metadata of the shape against which the shape intersected. This metadata is different from [method Object.get_meta], and is set with [method Physics2DServer.shape_set_data].
collider_id: Id of the object against which the shape intersected.
collider: Object against which the shape intersected.
rid: [RID] of the object against which the shape intersected.
linear_velocity: The movement vector of the object the shape intersected, if it was a body. If it was an area, it is (0,0).
If the shape did not intersect anything, then an empty dictionary (dir.empty()==true) is returned instead.

[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.

Check 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:
shape: Shape index within the object the point is in.
metadata: Metadata of the shape the point is in. This metadata is different from [method Object.get_meta], and is set with [method Physics2DServer.shape_set_data].
collider_id: Id of the object the point is in.
collider: Object the point is inside of.
rid: [RID] of the object the point is in.
[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.
