SetForcedInitialReplicatedProperty

native final function SetForcedInitialReplicatedProperty (Property PropToReplicate, bool bAdd)

adds/removes a property from a list of properties that will always be replicated when this Actor is bNetInitial, even if the code thinks the client has the same value the server already does This is a workaround to the problem where an LD places an Actor in the level, changes a replicated variable away from the defaults, then at runtime the variable is changed back to the default but it doesn't replicate because initial replication is based on class defaults Only has an effect when called on bStatic or bNoDelete Actors Only properties already in the owning class's replication block may be specified

• bAdd - true to add the property, false to remove the property

• inTimerFunc - the name of the function to call when the timer fires

SetZone

native final noexport function SetZone (bool bForceRefresh)

updates the zone/PhysicsVolume of this Actor

Note: ActorTemplate is sent for replicated actors and therefore its properties will also be applied at initial creation on the client. However, because of this, ActorTemplate must be a static resource (an actor archetype, default object, or a bStatic/bNoDelete actor in a level package) or the spawned Actor cannot be replicated
