teleport a rigidbody

Hi,

i want to releport my rigidbody. I will add a Force and if the rigidbody touches the trigger i will move the rigidbody to another position and the force should continue. The problem is the rigidbody is going crazy after moving. This is what im doing:

Code (csharp):

1.  
2. function OnTriggerEnter(other : Collider) {
3. //this is my rigidbody gameobject
4. other.gameObject.transform.position = exit.transform.position;
5. }
6.  

 

Looks fine to me. Maybe something else is causing the issue.

 

you can sleep it, then move the rigidbody (through rigidbody.position, not transform position) and wake it again. that should work I think.

 

i tried it but the behaviour of the rigidbody is not always the same. Sometimes it will drop down like a stone and sometimes it will be faster as before

 

Have you tried something like this:

1) store rigidbody.velocity
2) store rigidbody.angularvelocity
3) sleep rigidbody
4) deactivate gameObject
5) move gameObject
6) activate gameObject
7) forcibly reset rigidbody.velocity/angularvelocity
8) wake rigidbody

----

Maybe swapping 7/8 if the first attempt doesn't work? You prooobably don't need to deactivate the gameObject, but you said simply sleeping/waking the rigidbody wasn't working - so it's worth a shot.

 

the way to move it would be:
1. record the velocity. (rigidbody.velocity)
2. set the rigidbody to kinematic (isKinematic = true)
3. move the transform to the new location
4. set isKinematic = false
5. recompute the new velocity direction (that is based on the in and out portals orientations and the initial rigidbody velocity)
6. set rigidbody.velocity = to the transformed initial rigid body velocity.

EDIT: I just saw that Kyle posted 3 min. before me.
I did not post to correct his approach. In fact his approach seems good to me. If the portals are oriented in the same way, you don't have to worry about transforming the velocity vector.

 

No offense taken
I don't work with rigidibodies for the most part; was just a stab-in-the-dark attempt on my part. Didn't even think to take the orientations of the portals into consideration

Whatever gets the OP up and running is, as they say, for the win.

 

@ivkoni @KyleStaves i tried your approaches but the problem is the same. The behavior is not always the same. Sometime the rigidbody goes crazy. Sometimes it drop downs.... :-(

 

I'd check to make sure you don't have anything solid in the destination area that the object could intersect with. If you do, it'll cause the crazy physics you're experiencing.

 

It's absurd that Unity makes these things so difficult.
