Is there no way to list all components attached to a view?

What do you want to achieve with that/what's your use-case?

Let's say I have 2 views shipA and shipB. I add some

FollowComponent

to shipA that tells it to follow shipB. Later something changes and I want to do

shipA.getComponent<FollowComponent>().target = shipC

I have that implemented this way, but it seemed a bit hacky...

inline fun <reified T : Component> BaseView.getComponent(): T {
    return getOrCreateComponentOther<T> { error("No component of type ${T::class.simpleName}") }
}

So you don't need to iterate all the components, but to get a component that should be existing already, or throw an exception if it is not the case, right?

Correct (for my specific case)
