^^^ need review. Вы же этого ожидали? @TheKarasik @if0ne @Crechted @ainurdada

Может PerObjectData isDirty сделать через Event и подписку?

Пока что я не очень понимаю, как это будет доходить до сюда

Может PerObjectData isDirty сделать через Event и подписку?

А что будет в ивенте?

[damibran]

Ну главная проблема в чем: в случае PerObjectData изменяется TransformComponent, а уведомить об изменении нужно какой-то IRenderable.

Я думаю, в TransfromComponent нужно добавить Dispatcher/Notifier, который будет триггериться во всех сеттерах TransfromComponent, если он впервые становится грязным. А подписаться\присоединиться к этому может любой.
