Wire
Wire is a mechanic introduced in Chip's Challenge 2. It technically not a tile, but instead enables floor and steel walls to carry a signal between various game elements. Pink buttons, black buttons, and logic gates are capable of outputting a signal, and many more tiles can take signal as input. Wires will also be activated if Chip, Melinda, a ghost, or a rover step on it while equipped with the lightning bolt.
Blue teleports can be connected together with wire. If a movable object enters such a teleport network, it must exit a teleport in the same network. Teleports that are not in a network can still link to teleports inside a network. Signal has no effect on these networks.
The lightning bolt, when equipped by a moving object, will supply signal to a wire while stopped on one. The lightning bolt has no effect on wires that are already activated.
Tiles that accept signal input
A value of pulse in the toggle type column indicates that the tile only needs one frame of signal to toggle, while steady indicates that the tile will be toggled only when the signal is active.
| Tile | Toggle type |
|---|---|
| Force floors | toggle |
| Swivel doors | toggle |
| Toggle walls | toggle |
| Red teleports | steady |
| Flame jets | toggle |
| Transmogrifiers | steady |
| Clone machines | toggle |
| Traps | steady |
| Railroad tracks | toggle |
Buttons and Switches
Pink button
The pink button is a button introduced in Chip's Challenge 2. While held by Chip, Melinda, blocks, and monsters, it activates any wire it is connected to.
Pink buttons do not relay currents, unlike black buttons and blue teleports.
Black button
The black button is a button introduced in Chip's Challenge 2. It has the opposite behavior of a pink button: it activates any wire it is connected to except while held by Chip, Melinda, blocks, and monsters.
If a black button receives a current from any side, it will relay that current to the side opposite of that from which it is received.
Switch
The switch is a special tile in Chip's Challenge 2. When set to the on position, a current will be output through wire that is connected to the switch. When set to the off position, no current will be output. Switches can be toggled by Chip, Melinda, player mirrors, blocks, monsters, and bowling balls.
Logic Gates
Logic gates perform a logical operation on one or two wire inputs and produce a single output. They consist of the inverter, AND gate, OR gate, NAND gate, and XOR gate. There also exist NOR and XNOR logic gates, but these are not present in Chip's Challenge 2.
Inverter
The inverter, also called the NOT gate, accepts a single input and inverts the signal. If its input signal is ON, the output signal will be OFF. If its input signal is OFF, the output signal will be ON.
| INPUT | OUTPUT |
| A | NOT A |
| 0 | 1 |
| 1 | 0 |
AND gate
The AND gate accepts two inputs. If both inputs signals are ON, the output signal will be ON. Otherwise, the output signal will be OFF.
| INPUT | OUTPUT | |
| A | B | A AND B |
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
OR gate
The OR gate accepts two inputs. If at least one of the input signals are ON, the output signal will be ON. Otherwise, the output signal will be OFF.
| INPUT | OUTPUT | |
| A | B | A OR B |
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
NAND gate
The NAND gate accepts two inputs. It is equivalent to an AND gate immediately followed by an inverter. If both input signals are ON, the output signal will be OFF. Otherwise, the output signal will be on.
| INPUT | OUTPUT | |
| A | B | A NAND B |
| 0 | 0 | 1 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
XOR gate
The XOR gate gate accepts two inputs and performs an exclusive or operation. If one or the other of the two input signals is ON, the output signal will be ON. If neither input signals are ON or both input signals are ON, the output signal will be OFF.
| INPUT | OUTPUT | |
| A | B | A XOR B |
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
Other Tiles
Counter
The counter is a gate with two inputs and two outputs. A pulse that enters the counter from right side will increment the it by one and from the right side will decrement it by one. If the counter is incremented while at 9, it will overflow, output a pulse to the left side, and wrap to 0. If the counter is decremented while at 0, it will underflow, output a steady signal to the top side, and wrap to 9.
Latch
The latch gate has two inputs and one output. The arrow points from the data input to the output, and the input on the opposite side is the latch input. As long as the latch input has a signal, the output will be the same as the data input. When the latch input has no signal, the output will stay the same as it was when the latch input last had a signal. Latch gates can be thought of as storage for one bit of memory.
The second latch pictured to the right is a mirror image of the first latch, used to keep the game elements symmetrical.
