StructureSpawn API Hub
A focused hub for spawnCreep(), renewCreep(), recycleCreep(), Spawn return codes, and capacity planning.
Spawn work is more than memorizing one creation call. Name, body, Energy, busy state, replacement timing, and return codes belong to one lifecycle workflow.
API
Covered API surfaces
These entries come from the shared quick-reference dataset. The highest-value surfaces stay visible; secondary entries remain available on demand.
spawn.renewCreep(creep)
Use an owned Spawn to extend an eligible normal Creep's lifetime while accounting for Spawn occupancy and Boost limits.
Open in API reference →spawn.recycleCreep(creep)
Recycle a Creep you no longer need. The target must be near your Spawn and should be treated as an explicit one-way task.
