    Hello Everyone,
    1) is it possible to use Classes inside Jobs in any unsafe way ?
    2) is possible to link a classes to an entity ?

    1) no, you can't pass a class reference to a job
    2) yes but you loose performance

    unity ecs is so fast because it vectorizes data
    only value types can be vectorized, the object is a reference type, so when you accessing the object via entity you getting a cache miss
