Structs Building

Important: Entity IDs containing dashes (like 1-42, 5-10) are misinterpreted as flags by the CLI parser. All transaction commands in this skill use -- before positional arguments to prevent this.

Procedure

1. Check requirements — Player online, sufficient Alpha Matter, valid slot (0-3 per ambit), Command Ship online, fleet on station (for planet builds). Query player, planet, fleet.
2. Initiate build — structsd tx structs struct-build-initiate --from [key-name] --gas auto --gas-adjustment 1.5 -y -- [player-id] [struct-type-id] [operating-ambit] [slot]. The [operating-ambit] argument must be a lowercase string: "space", "air", "land", or "water" (not a bitmask number).
3. Proof-of-work — structsd tx structs struct-build-compute -D 3 --from [key-name] --gas auto --gas-adjustment 1.5 -y -- [struct-id]. This calculates the hash, auto-submits complete, and the struct auto-activates. No separate activation step needed.
4. Optional — Move, set defense, or activate stealth as needed.

Auto-activation: Structs automatically activate after build-complete. Use struct-activate only to re-activate a struct that was previously deactivated with struct-deactivate.

Compute vs Complete

struct-build-compute is a helper that performs proof-of-work and automatically submits struct-build-complete with the hash results. The struct then auto-activates. You only need struct-build-complete if you computed the hash through external tools and want to submit it manually.

The -D Flag

The -D flag (range 1-64) tells compute to wait until difficulty drops to the specified level before starting the hash. Difficulty decreases logarithmically as the struct ages. Use -D 3 — at D=3, the hash is trivially instant and zero CPU is wasted. Lower values wait longer but burn no compute on hard hashes.

Charge Costs

Every action consumes charge. Charge accumulates passively at 1 per block (~6 sec/block).

If you get a "required charge X but player had Y" error, wait for charge to accumulate. See knowledge/mechanics/building for the complete charge table.

Expected Build Times

Time from initiation until compute completes (assuming 6 sec/block, D=3):

Initiate early, compute later. The age clock starts at initiation. Batch-initiate all planned builds, then launch compute in background terminals. Do other things while waiting. See awareness/async-operations.

One key, one compute at a time. Never run two concurrent *-compute jobs with the same signing key. Both jobs may reach the target difficulty simultaneously and submit transactions with conflicting sequence numbers — one fails silently, leaving the struct stuck in build status. Use separate signing keys for separate players, and sequence compute jobs for the same player.

Commands Reference

Limits: 1 PDC per player, 1 Command Ship per player. Command Ship must be in fleet. Generator infusion is IRREVERSIBLE. Common tx flags: --from [key-name] --gas auto --gas-adjustment 1.5 -y.

Verification

• structsd query structs struct [id] — status = Online (or Built/Offline if not activated)
• Struct appears in planet/fleet struct list
