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.
How to Debug spawnCreep() Return Codes in Screeps
Validate the Spawn, Creep name, body, Energy, Memory, and optional structures; run dryRun first; preserve the real spawnCreep() result; and map each error code to a concrete fix.
How to Build a Screeps Creep Body from Available Energy
Distinguish current Energy from room capacity, repeat a role-specific body unit, enforce the 50-part limit, calculate cost and spawn time, and decide when to spawn a smaller emergency body.
How to Recover a Screeps Room with No Harvesters
Count current live harvesters, choose one idle active Spawn, require a minimum WORK-CARRY-MOVE body, use a unique name and dryRun, and prevent multiple Spawns from submitting duplicate recovery requests.
How to Use renewCreep() Safely in Screeps
Calculate the TTL and Energy gained per renewal, reject CLAIM Creeps, require explicit Boost removal approval, coordinate Spawn time, move adjacent, stop at a target TTL, and handle every documented result.
How to Recycle a Creep Safely in Screeps
Use an explicit one-time confirmation request, validate the named Spawn and Creep, move adjacent, submit recycleCreep() once, avoid an automatic suicide fallback, and verify disappearance and resource drops on the next tick.
