ArgumentException: The component has not been added to the entity. ???

ArgumentException: The component has not been added to the entity.

Getting this error but I have no information on what or where the actual problem is???

 

I have had a ton of these. And in the Console in a box that changes when you click on the line if you scroll down you can see the problematic lines.

It will be harder if it is "EntityCommandBuffer" as then the possible source of this is all possible command queuing in your project. But this is a possible message if you use Set/RemoveComponent while the entity does not have that component. (Maybe it was having the component, but by the time ECB play back command it is not anymore)

 

In my case, I had to have a CS file named as the Component Name. For example, if your IConponentData is MoveSpeed struct and Component is MoveSpeedComponent class then you must put them in a CS name MoveSpeedComponent.cs. Else Component System will not recognise it to add to the instantiated object.

 

Thank you, I am using EntityCommandBuffer and thank you, I can probably guess the offending lines. This is ruley.
