Variable value change when moving

Dear all,

I have two rooms. When I move between them I want to change a variable of an object.

west: TravelMessage {
        destination=Room02
        canTravelerPass(traveler) { return lamp.flagged; }
        explainTravelBarrier(traveler){ 
            "You can't the lamp is read."; 
            }
        travelDesc="You go west."
        }

I have an object “lamp”, and when I go west I want to change lamp_flagged to false AFTER I’ve checked if the move is possible (before or after the actual move, but after the check whether the move is okay). How do I achieve that?

Thanks and kind regards,
G.

The way I see it, you could do this in two ways.
One of which is by turning TravelDesc into a method, like so:

west: TravelMessage {
destination=Room02
canTravelerPass(traveler) { return lamp.flagged; }
explainTravelBarrier(traveler){
“You can’t the lamp is read.”;
}
travelDesc(){
lamped.flagged = false;
“You go west.”;
}
}

The other way to do this is by defining a noteTraversal method on the travel connector.

west: TravelMessage {
destination=Room02
canTravelerPass(traveler) { return lamp.flagged; }
explainTravelBarrier(traveler){
“You can’t the lamp is read.”;
}
noteTraversal(traveler)
{
lamped.flagged = false;
}
travelDesc=“You go west.”
}
