Practical Screeps articles for the problem you need to solve
Browse 81 published guides by system, difficulty, content type, or topic. Start with What Is Screeps? A Programming Strategy Game or follow the beginner sequence through How to Combine Your First Screeps Room Loop.
Screeps First Room: Find the Editor and Console
Open a Screeps Room, switch to the code editor and player Console, then use read-only checks to match exact Room, Spawn, Creep, Source, and Controller data.
Screeps First Room Code: A Small Loop You Can Verify
Combine three fixed beginner roles in one small loop, submit one validated Spawn request, keep Energy phases stable, expose failure statuses, and verify accepted commands on later ticks.
Screeps Creep Body Parts: WORK, CARRY, and MOVE
Inspect one Creep's active WORK, CARRY, and MOVE parts, then use its action result, Store, fatigue, and damage to diagnose missing abilities.
Screeps Creep Roles: Harvester, Upgrader, and Builder
Learn why Harvester, Upgrader, and Builder are player-defined responsibilities, how roles differ from body parts, and why a Creep name does not create behavior.
Screeps spawnCreep(): Create Your First Creep
Use dryRun to validate a WORK-CARRY-MOVE body, submit one safe spawnCreep() request, read its return code, and verify the new Creep across later ticks.
Screeps Ticks and Game Loop: Why Your Code Runs Repeatedly
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.
Screeps upgradeController(): Build Your First Upgrader Loop
Build one Upgrader1 loop that harvests from an active Source, moves within Controller range 3, spends Energy with upgradeController(), and switches state across ticks.
What Is Screeps? A Programming Strategy Game
Learn what Screeps is, how JavaScript controls its persistent world, and how Rooms, Creeps, Sources, Spawns, and Controllers work together for new players.
How to Build Your First Screeps Extension
Confirm RCL 2, place one Extension Construction Site, make Builder1 harvest and build it, and understand progress, capacity, and common failure states.
How to Make a Screeps Creep Build and Repair Automatically
Give Builder1 a clear priority: build owned sites, repair selected damaged structures, and upgrade the Controller when no higher task exists.
Publication standard
English articles are published only after source review, official API checks where applicable, JavaScript syntax review where code is present, duplicate-intent and link checks, and editorial review. Publication does not imply Console or multi-tick live-room verification; those evidence states remain separate in each guide. Review the verification method.
