ReplaceEvent

The information for a CheckReplacement event. You can mutate the variables in this event to change the result of replacement checking.

struct ReplaceEvent
{
   readonly class<Actor> Replacee;
   class<Actor>          Replacement;
   bool                  IsFinal;
}

Replacee

The actor class which is being replaced.
Replacement

What to replace it with. This class type is already effected by skill and actor definition replacements, so it may be useful to read it. Modify this to change what the resulting replacement class ends up being.
IsFinal

If true, the engine will not attempt to continue going down the replacement chain, and will directly replace the actor with Replacement.
