Lamp

Every shop has a lamp hanging from its ceiling, and a dark level in the Mines hangs more of them under its blocks. Hanging, a lamp is part of the scenery; when the block it hangs from is destroyed, it falls as a Lamp, a heavy item the player can carry and throw. On a dark level, carried or not, a plain Lamp lights the cave around it, as a Flare does. The Kissing Parlor's lamp is red, and falls as a red Lamp, which, unlike the plain one, lights nothing once it's down.

A hanging lamp isn't an item: it can't be picked up, and it flickers where it hangs ^[8]. When the block above it is destroyed, the block's last act is to replace it with a Lamp, red if the hanging lamp was, which then falls ^[9]. A shop's lamp hangs from the shop's ceiling, out of reach of a Bomb on the floor, and a lit bomb in a shop within 96 pixels of the Shopkeeper angers him ^{[10] [11]}. In the clip, in a Weapon shop whose shopkeeper is dead, the player throws a lit bomb up toward the lamp; it goes off under the ceiling, the block the lamp hangs from breaks, and the lamp drops to the floor ^[12].

A Lamp is picked up and thrown as any item is (Throwing), but it's heavy, like a Golden Idol: the player carries it in front of him at his own height, and throws it at 4 pixels a step plus his own speed, rising at 2, or at 4 upward ^{[13] [14] [15]}. He sets it down when he takes an exit, so it stays on its level ^[16]. Thrown faster than 2 pixels a step into a monster, it takes 1 hit point from the monster nearest it, as any thrown item does ^[17].

On a lit level a Lamp gives no light: there's no darkness for it to cut. On a dark level:

While the player is within 96 pixels of a red lamp, hanging or down, every light on the screen is tinted red ^[23]. The hanging red lamp is a kind of the plain one in the game's objects, so the code that lights the hanging lamps lights it too; the red Lamp isn't a kind of the plain Lamp, and the code that lights a Lamp's circle and widens the player's light names only the plain one ^{[1] [20]}. So a red Lamp carried through a dark level lights nothing but its tint.

The Lamp itself, the item, only ever comes from a hanging lamp's block: level generation makes none, and the level editor has no tile for either. In the second clip, the player throws a lit bomb up under the Kissing Parlor's ceiling, and its red lamp falls into the crater below, a red Lamp ^{[38] [39]}.

• Bombs. An explosion breaks the block a lamp hangs from, which brings it down, and throws a Lamp away from it without breaking it ^{[40] [41]}.
• Lava. A Lamp that touches lava stops and sinks, and is destroyed once it's under the surface ^[42].
• Water does nothing to a Lamp: the check that puts a Flare out is in the Flare's own code, and the Lamp has none ^[43].

• A plain Lamp is a light that water can't put out and that never runs out, but it can't leave its level: on a dark level, it's for lighting the way to the exit.
• A red Lamp is no use as a light: down, it lights nothing.

• The Lamp's create event is the Golden Idol's, its name and value changed: it's heavy, carried at the player's height as the idol is, and keeps a value, $1,000, and the idol's trigger, which only the idol's code reads, so picking a Lamp up sets off no trap, and an exit takes it from his hands rather than paying for it ^{[13] [44] [45] [46]}.
• The red Lamp's create event is the same as the plain one's, name and all: both are "Lamp" ^[47].
