Find the node which a shape belongs to using cordinates

Question

I'm currently in doubt if I can use coordinates(X,Y) to find if there is an shape in said coordinate, and if there is I would get/find the node which the coordinate is in belongs to?

Answer 1

If you want to find what PhysicsBody2Ds (StaticBody2D, RigidBody2D, KinematicBody2D) are at a given position, you can use a RayCast2D of length 0, placed at that position.

Or, you can use a Physics2DDirectSpaceState in a similar fashion as the RayCast2D would do behind the scenes…

Or better yet, use intersect_point:

var position:Vector2 = whatever_position_you_want_to_query()

var world:World2D = get_world_2d()
var space_state:Physics2DDirectSpaceState = world.direct_space_state
var collisions:Array = space_state.intersect_point(position)
for collision in collisions:
    var body:PhysicsBody2D = collision["collider"]
    print(body)

Or a shorter (with less explicit type information) version:

var position:Vector2 = whatever_position_you_want_to_query()

for collision in get_world_2d().direct_space_state.intersect_point(position):
    print(collision["collider"])

Note that the function get_world_2d is defined in CanvasItem and thus available in any derived types (Node2D, Control).
