Key and lock: Difference between revisions

A '''key''' is an [[item]] that Chip can use to open a '''lock''' (or '''door''') of the same color. Each key can only be used to open one lock after which it disappears, with two exceptions: the green key as [[Chip]] and the yellow key as [[Melinda]] in [[Chip's Challenge 2]] can be used an infinite number of times.

In [[Chip's Challenge 2]] and pedantic [[Lynx]], each player character can hold up to 255 keys of each colour; picking up a 256th key resets that colour's inventory back to 0. [[Tile World]]'s emulation of the Lynx ruleset, and the [[MS]] ruleset, do not have this restriction.

In Chip's Challenge 1, there is no way for the player to know how many keys of a certain colour they have, other than manually keeping count. In Chip's Challenge 2, if the player has between 2 and 9 keys, the appropriate number will be displayed in the inventory. If the player has 10 keys or more, a + sign is displayed instead; if the player has 128 keys or more, no symbol is displayed.

The '''blue key''' is [[Transparency|transparent]] on the Microsoft ruleset, and can be picked up only by [[Chip]] or [[Melinda]], who can use it to open one [[blue lock]]. In the [[Lynx ruleset|Lynx]] version, in addition to Chip, [[block]]s and [[monster]]s will erase blue keys after stepping on their tile. In [[Chip's Challenge 2|CC2]], the same holds true, but [[ice block]]s and [[directional block]]s do not erase blue keys, and monsters erasing blue keys are treated as collecting them, thus becoming unable to pass [[no sign]]s with blue keys on them.

If a dirt block collects blue keys and [[Transmogrifier|transmogrifies]] into an ice block, it can then open some amount of blue locks depending on how many blue keys it collected.

The '''red key''' is [[Transparency|transparent]] on the Microsoft ruleset, and can only be picked up only by [[Chip]] or [[Melinda]], who then can use it to open one red lock. It is the only key in the [[Lynx ruleset|Lynx]] version to act the same as its MS counterpart.

The '''green key''' is [[Transparency|transparent]] on the Microsoft ruleset, and can be picked up only by [[Chip]] or [[Melinda]]. In all versions of the game, Chip can use it to open any number of green locks, while Melinda in CC2 can only use it to open one green lock. In the [[Lynx ruleset|Lynx]] version, the green key acts as a [[wall]] to other [[object]]s.

The '''yellow key''' is [[Transparency|transparent]] on the Microsoft ruleset, and can be picked up only by [[Chip]] or [[Melinda]]. In all versions of the game, Chip can use it to open one yellow lock, while Melinda in CC2 can only use the yellow key to open any number of yellow locks.
