RigidBody2D Kinematic teleportation

Hi there! so in the docs it's said to use "MovePosition" for a "smooth" transition of a rigidbody (i'm using kinematic rigidbody 2D with interpolate), it also sais to use "rigidbody2d.position" to "teleport" the rigidbody instead, BUT, if i set the position for a teleport like it says i can see for 2-3 frames the game objet moving really fast from point B to point B, that issue DISSAPEARS if i disable the interpolate (interpolate = none), i tried by disabling the interpolate by code, then teleporting and again set the interpolate but it doesn't work because the process is really fast and i suppose that those changes needs at least 1 frame to be applied.

Any suggestions?

thanks!

 

I'm sorry english is not my native lang, ok let's go easy, i'm making a tower defense game, so i want the creatures move along the path as smooth as possible.

So i have teleports alont the path to instantly teleport creatures from point A to point B:
If i have interpolation, using "rigidbody2d.position = newposition;" does NOT transport the gameobject instantly, i can see (barely but i can) the game object moving really fast from it's current position to the new position, that DOESN'T happen if i turn off interpolation.

So what i need is to avoid that "glitch?" because if i move creatures along the path with "MovePosition" and it looks more smooth if interpolation is enabled, rigidbodies are kinematic by the way.

 

Ok so i'm using MovePosition with a lerp along a path, that's wrong? how should i do it then? is working really good now but i'll hear any recommendation

About the teleporting, the docs says "Teleporting a Rigidbody from one position to another uses Rigidbody.position instead of MovePosition."

So i'm doing it wrong cause interpolation? should i change the transform position then?

Thanks!

 

So ... i'm right? MovePosition with lerp for pathing.
rigidbody.position for teleporting, but you said it does not support interpolation so i can't use rigidbody.position for teleporting... i'm confused

 

Great, that's what i'm doing, so what about teleportation? (instantly change it's position)?

 

How should i do it? what's the "correct" form? because "Rigidbody2D.position = new position" does NOT move the gameobject instantly, i can see 3-4 frames moving really fast from the old position to the new one

 

I ran into a similar problem as Goty-Metal

What I can notice is that changing

Rigidbody2D.position

works the same way as

Rigidbody2D.MovePosition()

: they both interpolate through frames up to the next

FixedUpdate()

. I set

Rigidbody2D.interpolation = RigidbodyInterpolation2D.Interpolate

and

Project Settings => Time = 0.01

, and the interpolation can be observed clearly enough no matter whether it is

Rigidbody2D.position

or

Rigidbody2D.MovePosition()

that moves the object. Then I set

Rigidbody2D.interpolation = RigidbodyInterpolation2D.None

and non of those two make interpolation.

So, I can't understand I guess the same thing as Goty-Metal: why interpolation works with

Rigidbody2D.position

(since it shouldn't) and how to move an object with a Rigidbody2D without interpolation?

The only way it woks for me is turning interpolation off & on like this:

Code (CSharp):

1.  
2. Rigidbody2D rb = player.GetComponent<Rigidbody2D>();
3. RigidbodyInterpolation2D interpolation = rb.interpolation;
4. rb.interpolation = RigidbodyInterpolation2D.Interpolate;
5. rb.position += (Vector2)shift;
6. rb.interpolation = interpolation;
7.  

but it seems like there should be an easier way to do this and I'm missing something.

From docs:

But again, my experiments show that interpolation is applied in both cases. BTW nothing like this is said about Rigidbody2D:


I'm using Unity 2021.1.17f1

 

I think you can find the answer to your question in this thread:
