realtimetransform and rigidbody

im getting this when switching scenes, it seems to still be looking for a rigid body with a realtime transform maybe, MissingReferenceException: The object of type 'Rigidbody' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

Hi @Lost Wizard Corp.. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base.

----------------------
The error message you're seeing is indicating that a script is trying to access a component that has been destroyed. This could be due to a

RealtimeTransform

RealtimeTransform

component trying to synchronize the after it has been destroyed, possibly during a scene switch.

RealtimeTransform

RealtimeTransform

works differently when a component is present. If

RealtimeTransform

RealtimeTransform

detects a component, it synchronizes the and properties of the , which are in world space instead of local space. This is because PhysX simulates all rigidbodies in world space. Moving a Rigidbody via the Transform local position and rotation properties instantly teleports the Rigidbody and does not perform collision detection (source (https://normcore.io/documentation/realtime/networked-physics#realtimetransform--physics)).

If you're switching scenes and destroying objects with

RealtimeTransform

RealtimeTransform

and components, you might need to ensure that the

RealtimeTransform

RealtimeTransform

component is not trying to access the after it's been destroyed. You could do this by checking if the is null before trying to access it, or by ensuring that the

RealtimeTransform

RealtimeTransform

component is also destroyed when the is destroyed.

Also, remember that rigidbodies should not have parent game objects unless the parent never moves. This is because PhysX simulates all rigidbodies in world space, and synchronizing the world space position for rigidbodies can lead to unpredictable results if a Rigidbody component is synchronized, and then its parent is synchronized (source (https://normcore.io/documentation/realtime/networked-physics#realtimetransform--rigidbody-should-not-have-parents)).

If you're still having trouble, you might want to check the Normcore documentation (https://normcore.io/documentation) for more information or reach out to the Normcore support for help.

@Normcore Assistant do i need to disable the rigid body object before switching scenes

kapa.ai•7/15/24, 3:04 PM

Let me check the knowledge base for you. One moment!

kapa.ai•7/15/24, 3:04 PM

----------------------
The Normcore documentation does not specifically mention the need to disable the before switching scenes. However, it's generally a good practice in Unity to clean up any resources or references that might cause issues when a scene is unloaded.

If you're encountering issues with

RealtimeTransform

RealtimeTransform

and during scene switches, you might want to consider disabling or destroying these components before switching scenes. This could help prevent the error you're seeing.

Remember that you cannot add or remove a at runtime with

RealtimeTransform

RealtimeTransform

. If you need to add or remove a dynamically, Normcore recommends instantiating an empty prefab with a

RealtimeTransform

RealtimeTransform

and component on it, and destroying it when you're done (source (https://normcore.io/documentation/realtime/realtimetransform#extra-notes)).

If you're still having trouble, you might want to check the Normcore documentation (https://normcore.io/documentation) for more information or reach out to the Normcore support for help.

Call disconnect and wait before switching scenes
