This is an experiment on my part, I apologize if it's badly programmed (I'm really not very good at this) and I haven't programmed anything for a long time.
Basically this uses the function that hides under the cursor, but with this you can control it with script.
This is what I would like to use in the tutorial to help the player more easily see where the stations/stops are in cities with large buildings.
hidden_object_range(coord(pos.x,pos.y), 3)
hidden_object_stop()
