Redstone Signals
Most coaster blocks don't run on redstone wire. They run on a signal key.
A signal key is just a name you type, like station_a or doors. Every block with the same name reacts
together, wirelessly, however far apart they are.
You set a key by interacting with a block using the Coaster Wrench.
Your first wired ride
Give a block a key
Wrench the Station Rail and type a name — anything you like, one name per thing you want to control.
Control the signal
Crouch + use a Signal Remote and set it to the same name. A Control Panel button works just as well.
Press it
Use the remote. The station reacts instantly, from wherever you are standing.
Where keys come from
Signal Remote
The Signal Remote holds one key. Crouch + use to set the key, then use it to pulse that key on for 10 ticks.
It fires anything in the park without walking back to a Control Panel, which makes it the quickest way to test something you have just wired.
Control Panel
The Control Panel is the main way to make keys by hand. One panel can hold as many keys as your ride needs, each as one of two kinds:
Button
A quick pulse. Turns the key on for 10 ticks, then off again.
Lever
Stays on until you turn it off. Shared with every other lever using the same key.
Track Sensor
The Track Sensor makes a key fire on its own. It sits on a rail and holds its key on while a car is passing over it, for at least 4 ticks so quick passes still count.
This is the normal way to set off an effect as a car goes by, with no Control Panel involved at all.
Plain redstone
Ordinary redstone can drive a key too, through a Signal Converter in Emitter mode.
Signal Converter: the bridge
The Signal Converter translates between signal keys and real redstone, in whichever direction you need.
Receiver mode
Key in, redstone out. When its key is on, the block powers redstone at strength 15.
Emitter mode
Redstone in, key out. It reads the redstone reaching it and broadcasts that under a key you choose.
What listens for a key
Every block below takes a signal key, set with the Coaster Wrench.
| Block | What it does |
|---|---|
| Track Controller | Changes a stretch of rail to Basic, Brake, Boost or Chain Lift, at intensity 1-3 |
| Station Rail | Opens and closes the boarding gate |
| Switch Rail | Flips between its two exits |
| Entry Gate | Opens and closes |
| Technical Light | Turns on and gives off light |
| Coaster Anchor | Once it carries a station or a switch, it takes a key like the rail equivalent |
| Signal Converter | In Receiver mode, turns the key back into redstone at strength 15 |
