Question about the Wandering Mechanics

[Certh]

Curious about this mechanics,

I always think that Ghost's Favorite Room will always will be the place where the interactions will happen but sometimes there's interactions near its room.

Besides interactions, if I don't see interactions in its favorite room meaning it should be wandering all around the house right?

Ghosts have a radius around them that they can interact with objects within. For small maps, a ghost can touch/throw/interact with anything that is 1.5 meters of the ghost's location, which is not restricted by walls. For medium and large maps, the radius increases to 3 meters.

Ghost room vs not ghost room doesn't matter, as long as the ghost is within range of an object it can interact with it if it chooses to. If the ghost is inside the ghost room and there's a book on the other side of a wall in a different room that is within the interaction radius, the ghost can throw that book.

For the wandering mechanic, the ghost randomly picks a nearby coordinate and calculates the path that it would have to wander in order to reach that location. It can choose a short roam (3 meters max range) or a long roam (12 meters max range), unless it is a Goryo in which case it can only perform short roams. If the calculated wandering distance exceeds the maximum range of the type of roam that the ghost has chosen, it picks a new location to wander to and runs the distance check again.

At the end of a long roam, the ghost will run a check to see if it wishes to change its favorite room to its current location. If the check fails, ghosts will usually leash back to their favorite room after a short period of time. Goryos seem to leash back to their room after every short roam attempt if they leave the room bounaries.

If you don't see interactions in the ghost's favorite room, it could have wandered away or it could just be a very inactive ghost. It's usually best to confirm the ghost's presence in a room with motion sensors and thermometers rather than just interactions.

At the start of the investigation the ghost will pick a favourite room.

From there it can roam outside of the room, which can either be a short roam or a long roam. In both cases it will eventually come back to its favourite room. For higher difficulties (professional and above) the long roam has a chance to set the room it roams towards as their new favourite rooms, on lower difficulties it will simply keep its favourite room the whole investigation.

Furthermore a Goryo can never do a long roam and thus never changes ghost roam. A Banshee can roll for a long roam, but will instead walk towards its target player, which as well makes it impossible for the Banshee to change ghost rooms.

All other forms of activity, including events and hunts, are completely seperate in terms of RNG and will simply happen at the position it is right now. Now due to the ghost constantly walking back to its favourite room the chances of interactions happening in the ghost rooms are simply way higher than anywere else.

On top of that interactions are range based, so even if the ghost is in the next room, it might still be capable of touching items in adjacent rooms.

And if the lights are on in a room the ghost in, then it will not be capable of throwing items, so keep that in mind when evaluating the activity of a ghost. Other reasons for it to not do things might also simply be RNG coincidentally not rolling interactions for a while or not being close enough to an item it can interact (which is rather a problem for the bigger maps like highschool or prison though)

And lastly, evrey ghost rolls some activity sliders at the start, which can make it more or less active in general, so be careful in comparing ghosts from different games.

Thank you so much, finally getting the gist of it.
