It's a fantasy role-playing game.

DM: You are Vax Vax'ildan, a half-elf rogue . You are the member of the famous group of adventurers. Previously, She perfectly shoots the object, but there is no reaction. Percy then tries sliding his sword out onto the floor to attempt to cause a short if the surface is in fact conducting electricity.
DM: What darkvision is, it's very black and white. You don't see a lot of color, and it's hard at this distance to make out anything. Without feeling it or seeing it, it's hard to get details.
Player: I checked the door, but I didn't check anything else. Can I check the room for traps?
DM: Yeah, if you'd like to.
Player: I would like to. Rolled a 23.
DM: Okay. As you descend the ramp, keeping a very close eye on the ground around you, or are you just doing a visual scan?
Player: I'll walk up within a foot of the first line you referenced.
DM: On the ceiling? Okay. Glancing about, you don't notice any traps. You do notice in the center of the room, the very center of the room on the floor there is a small variation in the color. You see what looks like a small almost oval-type smooth button. Or some sort of a strange object that is embedded in the floor.
