[SOLVED]InvalidOperationException: Reflection data was not set up by a call to Initialize()

Hi,

I have a problem to schedule an IJobEntityBatch when my class inherit from a generic SystemBase class.
When I merge both classes, the code runs fine but separated not at all and the error is more an internal than a real error for the user.

Any idea ?

Thanks for your time

You'll want to start by looking here:

I have a generic base system for actions in my project, and that base system runs a generic job. In my systems that inherit from the base system I have to do something like this at the top of each:

Code (CSharp):

1. [assembly: RegisterGenericJobType(typeof(ActionProcessorJob<AttackAction, AttackActionProcessor>))]

 

@Jpritch71 I tried that yesterday without success but this morning that works thanks
Edit: I know why that was not working yesterday, I used RegisterGenericComponentTypeAttribute in place of RegisterGenericJobTypeAttribute because of a missing assembly def ref missing in my asmdef -_-

For Unity dev, Can you set a more explicite message because if you don't known what RegisterGenericJobTypeAttribute do, it's not clear what cause this assert message
