Editing Item

An '''item''' is a [[tile]] which [[Chip]] or [[Melinda]] can collect and store in their inventory. Aside from [[key]]s and [[computer chip]]s which have separate inventories, players can hold at most four items in their inventory at once. Although the computer chip is technically an item, it does not appear in the player's inventory like the other items.

There are specific tiles which are ''not'' considered items even though Chip can remove them: [[socket]]s, [[dirt]], fake [[blue wall]]s, [[lock]]s, etc. are not items. Chip can also move [[block]]s, but they are not considered items.

== Properties of items in CC1 ==
In the original [[Chip's Challenge 1]], the only items aside from [[keys and locks|keys]] and [[computer chip|chips]] are fire boots, flippers, ice skates, and suction boots. Items cannot be moved and can only be collected by Chip. [[Thief|Thieves]] will only steal boots, not keys.

These boots are [[acting wall]]s to [[monster]]s. In the [[MS ruleset]], blocks can be pushed over them; this is impossible in [[Lynx ruleset|Lynx]].

Monsters and blocks can pass over keys in MS. In Lynx, yellow and green keys are acting walls instead, red keys remain acting floor, and blue keys are erased by passing monsters and blocks.

In some circumstances in MS, items can be erased without Chip picking them up. The [[Non-Existence Glitch]] at the start of the game can remove them, or generally, other moving objects which pass over squares containing items on the lower layer of the [[grid]]: [[monster]]s erase any item on the lower layer of any square they enter, and Chip and [[block]]s will only erase items on the lower layer if the upper layer contains a non-[[floor]] tile which was not removed by the passage of Chip or the block. Such tile combinations are [[invalid tile|invalid]], rendering such levels unplayable in Lynx.

== Properties of items in CC2 ==
Most of the original properties of items apply in [[Chip's Challenge 2]]; however, the sequel also included multiple new items and mechanics. If the player attempts to pick up a fifth item, the last item in the player inventory is dropped to accommodate the new item. Players can also choose to rotate through the items in their inventory ('C' on the keyboard by default) and drop the last item in their inventory ('Q' on the keyboard by default).

Monsters and blocks can kill the player while the player is standing on or is about to walk onto an item, even if the item (not the [[terrain]]) normally prevents the monster or block from doing so. In Lynx, items do not behave differently in these circumstances.

Another new mechanic in CC2 is that certain [[monster]]s ([[ghost]]s, [[rover]]s, and [[player mirror]]s) and items (dropped [[bowling ball]]s and [[time bomb]]s) maintain their own inventory separate from the player inventory and can (with the exception of time bombs) also pick up items. In many cases, monsters can then use these items as the player would. All monsters and dirt blocks have the ability to pick up [[blue key]]s.

The solution to a number of CC2 puzzles involves strategically dropping items or passing items to monster inventories, allowing monsters to solve portions of the puzzle on the player's behalf.

== Items in both versions ==
The following items appear in both [[Chip's Challenge 1]] and [[Chip's Challenge 2]]:

=== Flippers ===
{{Infobox Tile
|name = Flippers
|cc1 = Yes
|cc2 = Yes
|cc1index = 104
|multidirectional = No
|moves = No
}}
'''Flippers''' allow [[Chip]] or [[Melinda]] to swim through [[water]] safely if they are unable to or do not wish to use blocks. Flippers do not, however, protect them from any [[glider]]s that may be swimming nearby.

In the original Atari [[Lynx ruleset|Lynx]], instead of flippers, a "water shield" is used.

{{clear}}
=== Fire boots ===
{{Infobox Tile
|name = Fire boots
|cc1 = Yes
|cc2 = Yes
|cc1index = 105
|multidirectional = No
|moves = No
}}
'''Fire boots''' allow [[Chip]] or [[Melinda]] to walk across [[fire]] safely. They do not, however, protect them from any [[fireball]]s that may be in the fire. In [[Chip's Challenge 2]], a [[ghost]] with fire boots will erase fire tiles they step on.

In [[Lynx ruleset|Lynx]], instead of fire boots, a "heat shield" is used.

{{clear}}
=== Ice skates ===
{{Infobox Tile
|name = Ice skates
|cc1 = Yes
|cc2 = Yes
|cc1index = 106
|multidirectional = No
|moves = No
}}
'''Ice skates''', or just '''skates''', allow [[Chip]] and [[Player mirror|mirror Chip]] to walk across [[ice]] at normal speed the same way he walks on ordinary floor, but have no effect when worn by [[Melinda]] or [[Player mirror|mirror Melinda]]. In the [[MS ruleset]], Chip can also step through ice corners from within the ice space that contains them across to another space, as long as the move is otherwise legal.

In [[Lynx ruleset|Lynx]] and [[Chip's Challenge 2]], instead of ice skates, ice cleats are used.

{{clear}}
=== Suction boots ===
{{Infobox Tile
|name = Suction boots
|cc1 = Yes
|cc2 = Yes
|cc1index = 107 
|multidirectional = No
|moves = No
}}
'''Suction boots''' or '''suction shoes''' allow [[Chip]] or [[Melinda]] to walk across [[force floor]]s at normal speed the same way he walks on ordinary floor.

In [[Lynx ruleset|Lynx]], instead of Suction boots, magnets are used, and in [[Chip's Challenge 2]], magno shoes are used.

{{clear}}
== Items exclusive to CC2 ==
The following items appear only in [[Chip's Challenge 2]].

=== Hiking boots ===
{{Infobox Tile
|name = Hiking boots
|cc2 = Yes
|multidirectional = No
|moves = No
}}
The '''hiking boots''', also known as '''dirt boots''', allow [[Melinda]] and [[Player mirror|mirror Melinda]] to walk over [[dirt]] and [[gravel]] tiles, but have no effect when worn by [[Chip]] or any other [[monster]].

{{clear}}
=== Speed boots ===
{{Infobox Tile
|name = Speed boots
|cc2 = Yes
|multidirectional = No
|moves = No
}}
The '''speed boots ''' allow [[Chip]] and [[Melinda]] to walk at twice their normal speed. The same is true for their [[player mirror|mirrors]] as well as bowling balls and ghosts. [[Rover]]s will walk at five tiles per second, just like regular monsters. Speed boots have no impact when sliding on [[force floor]]s or [[ice]].

[[Lesson 6 (CC2 level)|Lesson 6]] is the only official level that uses speed boots.

{{clear}}
=== Bowling ball ===
{{Infobox Tile
|name = Bowling ball
|image cc2 = [[Image:BowlingBall1.png]] [[Image:BowlingBall2.png]]
|cc2 = Yes
|multidirectional = Yes
|moves = Yes
}}
The '''bowling ball''', once picked up by the player or a monster, remains in the inventory until dropped. Then, it will travel in a direction until it is destroyed by a hazard or is otherwise blocked by an obstacle (unless it is sliding on ice or a force floor, in which case it rebounds off the obstacle or stays put, respectively). It is capable of destroying [[monster]]s and [[block]]s, picking up [[item]]s, pressing [[button]]s, and more.

Bowling balls have an inventory of four tools: if they grab a fifth, the first will be dropped.

{{clear}}
=== Bribe ===
{{Infobox Tile
|name = Bribe 
|cc2 = Yes
|multidirectional = No
|moves = No
}}
If [[Chip]] or [[Melinda]] holds at least one '''bribe''' in their inventory and step on a blue or red [[thief]], the bribe will be stolen but the rest of the inventory will be preserved. From monsters, a thief will take bribes, but not other items. If a player or monster has multiple bribes in their inventory, only one bribe will be used after stepping on a thief. 

It is only used in [[Lesson 6 (CC2 level)|Lesson 6]], [[Flea Market]], and [[Line and Sinker]].

{{clear}}
=== Helmet ===
{{Infobox Tile
|name = Helmet
|cc2 = Yes
|multidirectional = No
|moves = No
}}
The '''helmet ''' will make [[Chip]] or [[Melinda]] unable to be killed by [[monster]]s or moving [[block]]s. Monsters and moving blocks will instead treat Chip and Melinda as [[acting wall]] and vice versa. Similarly, monsters wearing the helmet will not be able to kill Chip or Melinda. Bowling balls are unaffected by helmets.

{{clear}}
=== Hook ===
{{Infobox Tile
|name = Hook
|cc2 = Yes
|multidirectional = No
|moves = No
}}
The '''hook''' allows the player and monsters to pull [[block]]s, [[ice block]]s, and [[directional block]]s. With the tool equipped, pulling happens automatically if Chip or Melinda walk directly away from the block and if the block is able to traverse the tile Chip or Melinda are currently standing on. It was first introduced in the level [[Flea Market]] and is used in only one level, [[Line and Sinker]], after its introduction.

If a movable object is in the process of moving into a space next to another movable object that is carrying a hook and attempting to move away from it, the hook will attempt to pull the former, even if it is not a block. This attempt will always fail, but it will cause the latter object to treat the space it is trying to move toward [[Acting wall|as a wall]] and the former object, once it lands on its space, to treat the latter object as a wall, even if the latter object is Chip or Melinda without a helmet (unless the latter object is after the former object in [[monster order]], in which case the player will die if they do not move to the side in time).

When equipped with a hook, the player can [[hook slap]].

=== Lightning bolt ===
{{Infobox Tile
|name = Lightning bolt
|cc2 = Yes
|multidirectional = No
|moves = No
}}
When the '''lightning bolt''' is equipped by a moving object, like [[Chip]], [[Melinda]], [[ghost]]s, [[rover]]s, or [[bowling ball]]s, they will supply signal to the bare [[wire]] underneath. The lightning bolt has no effect on wires that are already activated, nor does it affect logic gates, wired buttons, or wires buried under elements.

{{clear}}
=== Railroad sign ===
{{Infobox Tile
|name = Railroad sign
|cc2 = Yes
|multidirectional = No
|moves = No
}}
The '''railroad sign''' or '''railroad crossing sign''', often abbreviated as '''RR sign''', allows [[Chip]], [[Melinda]], [[player mirror]]s, [[bowling ball]]s, and [[rover]]s to cross [[railroad track]]s as if they were floor, although if they enter and exit a railroad with a track switch "legally", the track will still cycle. It has no impact on [[ghost]]s.

{{clear}}
=== Secret eye ===
{{Infobox Tile
|name = Secret eye
|cc2 = Yes
|multidirectional = No
|moves = No
}}
The '''secret eye''', often shortened to '''eye''', when equipped by [[Chip]] or [[Melinda]], reveals the identity of [[invisible wall]]s, [[hidden wall]]s, [[blue wall]]s, [[green wall]]s, content under [[block]]s, and content under [[Tent canopy|canopies]], and it gives a unique look to [[floor mimic]]s. It has no impact on monsters.

{{clear}}
=== Steel foil ===
{{Infobox Tile
|name = Steel foil
|cc2 = Yes
|multidirectional = No
|moves = No
}}
'''Steel foil''', commonly shortened to '''foil''', allows [[movable object]]s to change normal [[wall]]s into [[steel wall]]s by pushing on them. Walls can also have steel [[wall slapping|slapped onto them]]; however, [[hidden wall]]s and real [[blue wall]]s have to be revealed before they can be converted to steel, and so would require two slaps to become steel walls if never touched directly, or touched for at least 2 frames otherwise. [[Invisible wall]]s are never affected by steel foil, despite taking on the appearance of a normal wall when made contact with.

{{clear}}

=== Time bomb ===
{{Infobox Tile
|name = Time bomb
|cc2 = Yes
|multidirectional = No
|moves = No
}}
{{main|Time bomb}}
When a '''time bomb''', also known as '''dynamite''', is left behind by [[Chip]] or [[Melinda]] on a tile with no [[no sign]], the time bomb will count down for about 4.3 seconds before exploding.

{{clear}}
=== Yellow teleport ===
{{Infobox Tile
|name = Yellow teleport
|image cc2 = [[File:YellowTeleport.gif]]
|cc2 = Yes
|multidirectional = No
|moves = No
}}
{{main|Yellow teleport}}
The '''yellow teleport''' is technically a [[terrain]] tile, but if the exit directions for all yellow teleports except the one being entered are blocked or are covered, the player or moving tile (excluding [[ice block]]s and [[directional block]]s) will collect the yellow teleport as if it were an item. It can then be dropped on another floor tile as long as no item is currently on that tile (even if it is under a [[no sign]]).
