Methods
cast_motion(PhysicsShapeQueryParameters2D)
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 PhysicsShapeQueryParameters2D 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 [1.0, 1.0] will be returned.
Note: Any Shape2Ds that the shape is already colliding with e.g. inside of, will be ignored. Use PhysicsDirectSpaceState2D.collide_shape to determine the Shape2Ds that the shape is already colliding with.

collide_shape(PhysicsShapeQueryParameters2D, int)
Checks the intersections of a shape, given through a PhysicsShapeQueryParameters2D object, against the space. The resulting array contains a list of points where the shape intersects another. Like with PhysicsDirectSpaceState2D.intersect_shape, the number of returned results can be limited to save processing time.
Returned points are a list of pairs of contact points. For each pair the first one is in the shape passed in PhysicsShapeQueryParameters2D object, second one is in the collided shape from the physics space.

get_rest_info(PhysicsShapeQueryParameters2D)
Checks the intersections of a shape, given through a PhysicsShapeQueryParameters2D 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.
Note: This method does not take into account the motion property of the object. The returned object is a dictionary containing the following fields:
collider_id: The colliding object's ID.
linear_velocity: The colliding object's velocity Vector2. If the object is an Area2D, the result is (0, 0).
normal: The collision normal of the query shape at the intersection point, pointing away from the intersecting object.
point: The intersection point.
rid: The intersecting object's RID.
shape: The shape index of the colliding shape.

intersect_point(PhysicsPointQueryParameters2D, int)
Checks whether a point is inside any solid shape. Position and other parameters are defined through PhysicsPointQueryParameters2D. The shapes the point is inside of are returned in an array containing dictionaries with the following fields:
collider: The colliding object.
collider_id: The colliding object's ID.
rid: The intersecting object's RID.
shape: The shape index of the colliding shape.
The number of intersections can be limited with the max_results parameter, to reduce the processing time.
Note: ConcavePolygonShape2Ds and CollisionPolygon2Ds in Segments build mode are not solid shapes. Therefore, they will not be detected.

intersect_ray(PhysicsRayQueryParameters2D)
Intersects a ray in a given space. Ray position and other parameters are defined through PhysicsRayQueryParameters2D. The returned object is a dictionary with the following fields:
collider: The colliding object.
collider_id: The colliding object's ID.
normal: The object's surface normal at the intersection point, or Vector2(0, 0) if the ray starts inside the shape and hit_from_inside is true.
position: The intersection point.
rid: The intersecting object's RID.
shape: The shape index of the colliding shape.
If the ray did not intersect anything, then an empty dictionary is returned instead.

intersect_shape(PhysicsShapeQueryParameters2D, int)
Checks the intersections of a shape, given through a PhysicsShapeQueryParameters2D object, against the space. The intersected shapes are returned in an array containing dictionaries with the following fields:
collider: The colliding object.
collider_id: The colliding object's ID.
rid: The intersecting object's RID.
