In City From Naught's post-apocalyptic builder, conventional conveyor belts do not exist. Instead, mastering Brave New Wonders signals is the single most vital skill for coordinating your mobile workforce across complex supply chains. Without a clear command network, mover automatons quickly clog up production facilities, stall smelters, or misplace critical crafting materials. Learning how to properly configure Brave New Wonders signals transforms chaotic stockpiles into responsive, self-regulating logistics networks that adapt to dynamic factory conditions in real time.
Whether you are trying to balance the volatile temperature of a fusion reactor or keep delicate greenhouse crops from rotting, broadcast logic forms the backbone of an efficient base. This comprehensive guide breaks down how signal intelligence operates, how to solve the Academy tutorial trials, proper text prompt phrasing, and advanced multi-biome logistics.
Understanding Signal Intelligence and Event-Driven Logic
In standard factory automation games, physical conveyor belts dictate material flow and spatial layouts. Brave New Wonders replaces static belts entirely with autonomous robotic units. Every ore chunk, metal plate, and refined crystal travels via programmed automatons. While basic routines allow a mover bot to loop between two points, unmonitored loops frequently cause bottlenecks when a machine fills up or runs dry of essential resources.
Signal intelligence introduces event-driven programming to solve this problem. Every production facility, warehouse, and special monument can monitor internal and external parameters and broadcast a colored signal. Automatons read these broadcast states across the network to switch priorities immediately.
The behavior editor compiles plain-text commands into a visual state diagram. Each node represents an action like fetching an item, traveling to a waypoint, or dumping cargo, while the transitions between nodes represent logic checks. By tying transitions to broadcast colors, your workforce operates only when the receiving facility is ready. According to developer notes, recent updates expanded the color spectrum beyond the classic red and green to include blue, pink, orange, black, and white, granting players immense flexibility for multi-step prioritization.

Core Signal Tutorials: Item Sorting and Warehouse Routing
Before venturing deep into the campaign, the in-game Academy strongly recommends completing the Signal Intelligence tutorial. These trials illustrate the fundamental relationship between broadcast emitters and receiver units.
The initial exercise tasks you with routing an automaton between destination flags. Setting a warehouse to emit a green signal directs the mover to Flag B, while setting it to red reroutes it to Flag A. This foundational mechanic proves that a single mover can service multiple destinations dynamically based on storage thresholds rather than requiring dedicated units for every path.
The next exercise addresses mixed-resource sorting from a shared stockpile. A central building produces either metal ores or crystal shards at random and dumps them onto a communal pile. Two specialized warehouses flank the pile: one dedicated to metal and the other to crystal.
To prevent sorting errors, player experience demonstrates that configuring the receiving warehouses to broadcast distinct color conditions is essential:
- Configure the left warehouse or central stockpile to broadcast a pink signal whenever metal ore is detected.
- Configure the right warehouse or central stockpile to broadcast a blue signal whenever crystal shards are detected.
- Instruct the left mover automaton to collect items only when the pink signal is active and deposit them into the metal storage.
- Instruct the right mover automaton to collect items only when the blue signal is active and deposit them into the crystal storage.
| Trial Objective | Target Structure | Broadcast Condition | Automaton Assigned Task |
|---|---|---|---|
| Flag Routing | Primary Warehouse | Red / Green toggle | Route to Flag A on Red; Route to Flag B on Green |
| Metal Ore Sorting | Left Warehouse / Pile | Pink when metal present | Fetch metal ore; deposit into Left Warehouse |
| Crystal Sorting | Right Warehouse / Pile | Blue when crystal present | Fetch crystal; deposit into Right Warehouse |
| Counterweight Crane | Drone Wreckage Crane | Red when full / Green when empty | Deliver 10 plates on Green; extract on Red |
Implementing this logic prevents the common early-game pitfall where mover bots grab the wrong item, clog their inventory, and halt subsequent assembly lines.
Managing Dynamic Hazards: The Levitanium Sun and Sky Pillar
As you progress through the Americas continent, signals evolve from basic supply line management into life-or-death environmental controls. Two major campaign milestones require precise signal calibration: the Levitanium Sun reactor trial and the Sky Pillar excavation.
The Levitanium Sun tutorial challenges players to stabilize a colossal plasma fusion reactor. The goal is to maintain the reactor's core temperature between 20 and 30 Kelvin for a continuous 60-second window. Loading fuel cells rapidly increases the core temperature, and adding too many results in catastrophic overheating.
Achieving complete thermal stability requires an automated feedback loop between the reactor and the fuel supply bot:
- Select the Levitanium Sun and create a signal behavior that reads its core temperature.
- Set the reactor to emit a green signal when the temperature drops below 25 Kelvin.
- Set the reactor to switch to a red signal when the core rises above 25 Kelvin.
- Program the mover automaton to fetch a fuel cell from storage and deposit it into the reactor only when the green signal is visible.
Community reports and gameplay testing note that thermal inertia causes the temperature to continue drifting upward briefly after a fuel rod is inserted. Setting the shut-off threshold slightly conservative—around 24 or 25 Kelvin—ensures the core does not spike over the 30 Kelvin failure boundary.
A similar dynamic occurs at the Sky Pillar, situated southeast of the central train station. After clearing nearby hostile units with your monowheel drone gun and clearing barriers with dynamite, you build scaffolding and an exploratory crane. Strange atmospheric gusts blast through the central sinkhole, freezing or overheating the excavation machinery. The excavation progress stalls completely unless the platform temperature is held between 25 and 70 degrees. By utilizing Brave New Wonders signals, you can trigger delivery automatons to insert coal when the platform freezes, or deposit heat-resistant thermal plates when thermal surges occur.
Prompt Syntax, Variables, and Troubleshooting Signal Glitches
The game's text interpreter allows you to write commands in conversational language, which an internal language model parses into operational behavior trees. However, understanding how the game assigns variables prevents frustrating execution errors.
When scripting prompts, the engine detects brackets as instructions to generate selectable destination fields. For example, typing a command such as:
"When signalSource is red, move to warehouse and collect metal plate, then deliver to signalSource."
This generates assignable parameter slots in the automaton inspector. Players can then manually click the building icons on their map to bind the specific structures to the script.
However, community reports on the official Steam discussion boards highlight a common naming conflict when handling multiple items. If you write generic terms like "ItemType" twice in the same prompt, the parsing engine may bind both conditions to the identical item slot. To ensure the behavior graph distinguishes between separate resources, use distinct identifiers:
- Write "Item Type A" and "Item Type B" when instructing a single mover to fetch different materials based on alternating signals.
- Explicitly phrase commands like: "When Source is Red, pick up Item Type A from Storage; when Source is Blue, pick up Item Type B from Storage."
- If an automaton stops cycling, inspect the visual logic graph. In rare instances, a structure switching between colors enters an instantaneous neutral state, which can trigger an unintended fallback loop if an "else" branch is improperly defined.
- Click the discreet question mark icon located on the command interface. Many players overlook this button, yet it opens the full list of recognized system parameters, action instructions, and transition conditions supported by the behavior generator.
Checking the visual behavior graph before confirming an instruction prevents unexpected loops and ensures that the compiled state machine accurately reflects your operational intent.
Intercontinental Signal Automation Across the Archipelago
Once you construct your first flying Airship Wonder, your logistical scope expands beyond the temperate Americas into severe biomes across the Archipelago. Each continent introduces environmental constraints that make signal networks indispensable.
In the agricultural expanses of Africa, production challenges revolve around product freshness. High-tier crops grown in industrial greenhouses possess a strict spoilage half-life. If harvested goods sit unattended on a warehouse floor, they rot into useless waste, plummeting facility efficiency.
Pioneers must establish multi-condition sensor networks to manage this vulnerability. Greenhouses emit distinct signals indicating moisture levels, soil nutrient depletion, and current temperature. Automaton routines must evaluate environmental signals to balance irrigation pumps while coordinating rapid-response transport bots to deliver harvested goods to processing facilities before the decay timer expires.
In the volcanic territory of Asia, signals become vital safety measures. Standard mining operations are routinely interrupted by active tectonic shifts and deadly lava flows that incinerate automatons within seconds. Players cannot rely on static routing. Instead, industrial monitoring flags must broadcast evacuation signals when seismic activity spikes. Miners programmed with fallback logic can abort their active mining loops, drop their industrial scrap, and navigate to safe staging grounds until volcanic vents cool down.
Using Brave New Wonders signals across these extreme frontiers ensures your production networks remain resilient, maximizing resource extraction without suffering costly equipment losses.
Frequently Asked Questions About Brave New Wonders Signals
How do I stop mover automatons from getting stuck with full inventories?
Automatons commonly freeze when their destination facility fills up while their personal inventory is packed with raw materials. You can resolve this by programming the manufacturing building to broadcast a signal (such as red) when its input capacity drops below five units. Configure the mover to deliver raw resources only while the signal is active, and add an alternate branch that clears finished products from the output slot whenever the facility is full.
What colors are available for Brave New Wonders signals?
In addition to standard Red and Green indicators, the game supports Blue, Pink, Orange, Black, and White signals. This expanded color palette allows players to design intricate, multi-state production lines where buildings can request numerous distinct ingredients without overlapping color states.
Why is my automaton ignoring a signal change in the prompt graph?
If an automaton fails to respond when a signal changes, open its inspector window to view the live behavior diagram. This issue frequently occurs when variables share identical names (like using generic "item" instead of "Item Type A" and "Item Type B"), or when an instruction lacks an explicit fallback condition. Defining explicit states for every color prevents the unit from hanging in an unassigned transition state.
