SEARCH + DIAGNOSTICS
Search discovers the most relevant guides, references, return codes, and tools. When the answer is still uncertain, continue through symptom diagnostics, API surfaces, and accepted Runtime Evidence.

When Market deal/createOrder fails, inspect order arguments, Credits, resources, Terminal state, and transaction Energy cost rather than price alone.
Screeps API surface: Game.market.createOrder(params).
Screeps API surface: Game.market.deal(orderId, amount, roomName?).
Prefer low-risk, reversible, or read-only checks; when a real transaction is required, verify only the smallest explicit case and record limitations.
A focused hub for Game.market deals, order creation, Terminal transport budgeting, and Market tools.
A focused hub for Terminal sends, transaction Energy, stock, cooldown, and Market cost planning.
Calculate Terminal transaction Energy, effective Market deal prices, maximum Energy payload, and order creation fees.
Search common Game, Creep, Room, Structure, Market, and PathFinder APIs and continue to matching guides or official documentation.
High-frequency Screeps error codes with diagnostic paths into APIs, object hubs, guides, tools, and runtime verification.
Freeze one reviewed deal revision, reserve both an account deal slot and the exact Terminal, submit once, and verify the new transaction ID and actual partial or full amount next tick.
Bind one request to three exact Lab IDs, snapshot both reagent types and Stores, submit once, and verify the product and two reagent deltas under an exclusive action window.
Start from visible symptoms such as a Creep not moving, Spawn failures, Controller downgrade pressure, Link transfer problems, Market failures, high CPU, or stalled logistics, then continue into return codes, APIs, object hubs, guides, tools, and runtime verification.
Find the action that returned ERR_NOT_IN_RANGE, use its documented range, submit movement separately, and retry the action on a later tick.
Change, extend, or cancel one owned Screeps market order with nullable room fingerprints, conservative fee budgeting, one-writer request IDs, raw return codes, and next-tick state verification.
Browse 6 published English guides related to Market.
Plan compound reaction chains, base minerals, Lab runs, production ticks, and Boost batches.
Freeze one transfer revision, reserve the exact Terminal against send and market-deal conflicts, submit once, normalize ledger descriptions, and verify the actual full or partial outgoing transaction next tick.
See which high-frequency diagnostic paths have accepted Console or live multi-tick verification, what evidence is missing, and which runtime checks should come next.
Understand a Screeps tick, Game.time, and module.exports.loop, then run safe observations that show why actions and state changes appear across later ticks.
A focused hub for Lab reactions, Boosts, mineral and Energy prerequisites, cooldown, and production planning.
A structured map for Memory, spawning, economy, movement, Controllers, defense, market systems, and debugging.
Topic archives for Memory, spawning, Creeps, Energy, movement, pathfinding, Controllers, construction, defense, market systems, resources, CPU, debugging, and JavaScript.
Browser-based body, room, Market, Controller, Lab, Spawn, hauling, and Tower tools that do not request a Screeps token or connect to an account.
Choose between getRangeTo(), inRangeTo(), isNearTo(), isEqualTo(), findClosestByRange(), findClosestByPath(), and findInRange() without confusing linear range with route reachability.
Freeze one reviewed order revision, reserve the creation fee and account mutation slot, call createOrder once, and verify the exact new order ID in the next account snapshot.
Learn StructureLab.boostCreep() requirements, bodyPartsCount usage, return codes, current-tick scheduling, and how to verify exact boosted body parts afterward.
Separate permanent Factory level from the active Power effect, snapshot every recipe component, submit one batch, and verify exact output and component deltas under an exclusive Store window.
Validate the same-tile Extractor and Miner, record only accepted harvest calls, match the exact EVENT_HARVEST on the next tick, and separate event identity from Store overflow and depletion.
Recover an owned active Power Spawn, calculate base and PWR_OPERATE_POWER processing amounts, require Power and POWER_SPAWN_ENERGY_RATIO Energy, preserve a configurable room reserve, store GPL and resource snapshots, handle return codes, and verify later deltas.
Inspect one Creep's active WORK, CARRY, and MOVE parts, then use its action result, Store, fatigue, and damage to diagnose missing abilities.
Enter acquire at zero Energy, enter work when full, preserve the previous phase at partial values, initialize explicitly, and keep state selection separate from actions and outcomes.
Save an ID with room and kind metadata, return explicit invalid, no-vision, missing, wrong-type, and ready states, and keep restoration separate from reselection and actions.
Enter Controller recovery with hysteresis, reject blocked or unready attempts, submit one upgrader action, and verify the exact Creep in the next tick's room event log.
Call PathFinder.search() with the goal range your action actually needs, interpret path, ops, cost, and incomplete correctly, and reject partial paths before handing movement to a Creep.
