    Normally I would put a JobHandle inputDependencies into the schedule function however ScheduleParallel expects "EntityQuery". What should I do to use this ScheduleParallel?

    Use SystemBase instead of JobComponentSystem.

    Take a look at the dependency section of the Entities Documentation. Essentially the new SystemBase takes care of the implicit dependencies of any jobs that you schedule. You are able to overload this by passing in a JobHandle to the ScheduleParallel function, but then you have to make sure to update the system dependency with your final JobHandle.

    As for the EntityQuery, if you pass it in then it will just filter which entities are selected for the job, based on the query, like the old job structure.
