How to get the distance between a Kinematic and a Rigid body in 3D

Question

so I'm learning Godot, and now I'm trying to get the distance (in pixels, meters, whatever) between the player and a rigidbody. Just like in this question, but in 3D.

I'm trying to apply_impulse to this rigidbody, but the impulse should be divided by the distance between them.

Comments

It's the same distance_to

i'm trying this:

var distance = get_node(".").distance_to(body)

*"body" is because I'm comparing to the body that entered in the area**

but it throws a invalid call, NonExistent Function in base KinematicBody.

any idea?

the distance_to function only works on Vector3s, so if you try:

var distance = get_node(".").translation.distance_to(body.translation)

that should hopefully work

Answer 1

With a sample scene tree defined like this:

Spatial
   +- KinematicBody
   +- RigidBody

Something like this (connected to the Spatial node) should work:

func _ready():
    var dist = $KinematicBody.transform.origin.distance_to($RigidBody.transform.origin)
    print(dist)

With the KinematicBody at 0,0,0 and the RigidBody at (10,10,0), that results in a distance of 14.142
