The 尖刺 and 木尖刺 are exceptions, as they are not mechanisms, but static placed items that simply cause damage on contact. The 地雷 is a trap-like item, though never generates naturally, and is instead purchasable during 困難模式.
All traps, including their triggers, are illuminated by the 危險感 buff, allowing the player to avoid and collect them. Their wiring can also be seen if the player holds a 機械-related item in their hand, for instance a pressure plate. The player can also see wires even in darkness if they have a 機械晶狀體 or Grand Design in their inventory
Reusable traps generally fire sharp projectiles. They can be activated infinitely with a few seconds delay.
These traps consist of spawn statues, such as skeleton statues, wired to a red or green pressure plate. A monster spawns if a player steps on it and if the plate is in the monster's way, each monster may spawn a new one, resulting in swarms of enemies, spawning until the spawn limit is reached.
Dart Traps fire a 中毒 dart which resembles a 木箭 when activated. When found naturally, they are always wired to 壓力板s in their line of sight. The Pressure Plate can sometimes be very far away from the Dart Trap.
Super Dart Traps function like ordinary Dart Traps, but do almost double the damage. They shoot what appears to resemble a 毒鏢, as opposed to an arrow. They are found in the 叢林神廟 only, and are the second most common trap in there.
Spiky Ball Traps drop a single spiky ball that bounces and persists for a long time before despawning. The projectile's prolonged lifetime allows it to do significant damage to anything in its path, which comes in handy for terrain often traversed by enemies. Spiky Ball Traps are found in the 叢林神廟 only, and are the most common of the traps in there.
Spear Traps deploy a long spear down from the block, which can reach surprisingly far lengths if not obstructed. They have a shorter activation period than other traps. They are found in the 叢林神廟 only, and are the second most rare trap in there (Only succeeded by 烈焰機關s). They are never found in the large main room, because of the high ceiling and how all natural generated 長矛機關s always point downward.
Flame Traps fire flames, similar to those of the 火焰噴射器, that extend 23 blocks with 1 block above and below, and inflict the 著火了！ debuff. They are found in the 叢林神廟 only, and are the most rare of the traps in there. Often, they don't even spawn in a world at all.
Geysers act like vertical Flame Traps, throwing fire and pushing up the player when touched. The fire they emit can pass through several blocks and still hit the player. They are found deep underground, usually near lava sources.
Boulder traps features a Pressure Plate wired to a 2x3 arrangement of 通電石塊s above it, with a Boulder resting on top. When the Plate is triggered, the stone blocks become inactive and the Boulder drops on the area below. They are dangerous in dark areas as players won't be able to see the boulder or pressure plate. They affect all entities, so when used properly can be used to defeat enemies and bosses.
Explosive traps come in two varieties, but are based around the same means of killing the player. The more common variant, found only on the Desktop version, is a 引爆器 wired to a nearby 炸藥 block, usually sitting atop a large ore vein. The rarer variant is a less visible 壓力板, usually buried nearby. In either case, the triggering device sits within the explosive radius of the block, causing the player to be caught in the explosion. There is no forewarning to this explosion, and Explosives deal upwards of 500 damage to entities caught in the blast, making undiscovered Explosives Traps dangerous well into 困難模式.
These grow naturally in the Corruption, Crimson and Underground Jungle respectively. Touching them will damage the player and destroy the block.
Will fall to ground when destroyed and releases Bees.
- Trap wiring displays on screen, meaning the player can hold an item like a 壓力板 to see wires underground that might be connected to darts or boulders.
- Randomly generated traps are a very cost-effective method of acquiring 電線 once you have a 鋼絲鉗, saving you 5 for every bit of wire collected (as opposed to purchasing Wire from the 機械師).
- When placed effectively, Traps can be useful in 事件.
- When multiple traps are naturally generated close to each other, their wiring may intersect. This leads to multiple traps with multiple triggers.
- Most traps deal double the damage to players In expert mode.(In addition to the double damage players normally take from traps).
- 188.8.131.52：Fixed bug where traps could critically hit.
- 184.108.40.206：Statue traps added.
- 1.2：Traps created upon world generation can no longer be triggered by mobs (they use different 壓力板s).
