// Reload actors that use a changed object

Should it be const? The name of the function implies it returns a list of entities, but it's actually a list of components ?

Same question for three below.

I think const is correct as no object member data is being modified.

I agree about misleading function name.

Usage is also not consistent among places.

My bad, actually const doesn't work here, generator needs to modify it's buffer pointer. By 'consistent' do you mean the variable name? I changed them all to gen.

I think we have ICmpPtr

Same question for all the occurrences of this.

I can't find any use of ICmpPtr.

My Bad. CmpPtr<ICmpVisual>

MercuryAuthorUnsubmitted

The CmpPtr template takes an entity as argument and gets the component through query interface so it isn't appropriate for iteration. Another constructor overload could wrap the static_cast but that seems like obfuscation to me.

Can we use the CCmpManager function for those too?

No, CComponentManager::BroadcastMessagesToInterface calls the HandleMessage method but these call Hotload.

Might make sense to make a hotload function then? Could be out of scope.

We would need two versions ( with and without argument ) and pass through functions in simulation2, doesn't seem worth it to me for only 3 instances.
