Summary
When using Entity.SetOrigin(NewOrigin) on a Scene Graph Entity, it freezes the game and after some seconds it crashes the server.
This only happen with that specific function, setting the origin throught other methods works as expected.

Steps to Reproduce
Try to use the following function on any scene graph entity:
(InEntity:entity).SetOrigin<native><public>(NewOrigin:origin)<transacts>:void
Example:
CustomOrigin := entity_origin {
Entity := SomeEntity
}
AnotherEntity.SetOrigin(CustomOrigin) # Crash when calling this
Expected Result
Origin is set and does not crashes the server
Observed Result
Server freezes and crashes
Platform(s)
Verse VM
Additional Notes
The comment on the Verse digest says:
# Sets the origin of this entity, in the case the entity does not have a transform_component it will create one and set its origin. This method fails if it recognized dependency recursion.
(InEntity:entity).SetOrigin<native><public>(NewOrigin:origin)<transacts>:void
It says that the function should fail when recognized dependency recursion, but the function is not <decides>. I believe this is an error when generating the digests, and that may be the reason why it is crashing the server when calling it (regardless of recursion actually existing or not).
As I mentioned earlier, setting the origin throught other methods (like directly on transform component) works fine, such as this example:
CustomOrigin := entity_origin {
Entity := SomeEntity
}
if (TransformComponent := AnotherEntity.GetComponent[transform_component]) {
set TransformComponent.Origin = option{CustomOrigin} # Works fine
}
I tested other methods (such as Entity.ResetOrigin() and Entity.GetOrigin[]) to check and these works fine. The crash only happens with the Entity.SetOrigin() method.
I noted this issue on v37.00, but after some digging, looks like the <decides> was removed from it in v36.0, so that may be the version that the bug started existing:
- @experimental
# Sets the origin of this entity, in the case the entity does not have a transform_component it will create one and set its origin. This method fails if it recognized dependency recursion.
- (InEntity: entity).SetOrigin<native><public>(NewOrigin: origin)<transacts><decides>: void
+ (InEntity: entity).SetOrigin<native><public>(NewOrigin: origin)<transacts>: void
