In Godot 2.X like this:

if My Area.get_overlapping_bodies () [n] extensions RigidBody:

I have checked that the intersection occurred with a RigidBody. It doesn’t work in Godot 3.X. How can I verify that “Area” intersects with “RigidBody”?

First retrieve list of overlapping boddies var bodies = area.get_overlapping_bodies()
Then check if boddies contains your body of interest if bodies.has(my_rigidbody): do_some_stuff();

Then check if boddies contains your body of interest if
bodies.has(my_rigidbody): do_some_stuff();

Bartosz, I do not need to check for intersection with a particular body (a scene node), but make sure that the intersection has occurred with any RigidBody. How to do it?

just check area.get_overlapping_bodies().empty()
true means there are no overlapping bodies, false means there is at least one overlapping body

Bartosz, that’s not what I wanted. I want to know the body type (node type) with which the intersection occurred (what this body: RigidBody, KinematicBody, StaticBody, etc.).

are yout asking about type check like this if body is RigidBody2D: do_something() ?

I don’t speak English. Probably… Yes.
I need:

  1. check check intersection with Area (true/false)
  2. If the intersection eat to check the body type, with which intersected Area

This is how it worked in Godot 2.X:

	if lp_Testor.get_overlapping_bodies().size()>0:
		var n=0
		for n in range(lp_Testor.get_overlapping_bodies().size()):
			if lp_Testor.get_overlapping_bodies()[n] extends RigidBody:
				lp_Testor.get_overlapping_bodies()[n].apply_impulse(Vector3(),Vector3(lp_Testor.get_overlapping_bodies()[n].get_mass()*4,0,0))
				marker_Deystvie=4
				lp_OstatokVremya=lc_Ogidanie_2

In Godot 3.X it does not work.

I’ve removed unnecessary if , replace indexing by number n with directly iterating elements and I’m using is instead of extends rest is your code:

for body in lp_Testor.get_overlapping_bodies():
	    if body is RigidBody:
	        body.apply_impulse(Vector3(),Vector3(body.get_mass()*4,0,0))
	        marker_Deystvie=4
	        lp_OstatokVremya=lc_Ogidanie_2
