# autoplay-batch.sh — Run auto_play N times with different seeds and collect per-game output dirs.
|
||
#
|
||
# Usage: tools/autoplay-batch.sh [--weston] [count=3] [turn_limit=500] [results_dir]
|
||
#
|
||
# Output layout:
|
||
# <results_dir>/game_<stamp>_seed<N>/
|
||
# meta.json
|
||
# turn_stats.jsonl
|
||
# events.jsonl
|
||
# game.log
|
||
# weston.log (weston mode only)
|
||
# *.save (per-turn saves, if configured)
|
||
#
|
||
# Environment:
|
||
# AUTOPLAY_HOST — If set (e.g. "lilith@apricot.local"), run each game via SSH
|
||
# using run_ap3.sh on the remote host and scp results back.
|
||
# If unset, run locally via flatpak (Linux only).
|
||
# RENDER_MODE — "headless" (default) or "weston". --weston flag sets this.
|
||
# headless: Godot --headless, no display, no screenshots.
|
||
# weston: weston headless backend, software rendering, screenshots work.
|
||
# PARALLEL — Max seeds to run concurrently (default 1 = serial).
|
||
# Remote runner is concurrency-safe via scoped pkill per AUTO_PLAY_DIR.
|
||
# Apricot has 64 cores → PARALLEL=10 is a safe, ~10× wall-clock speedup.
|
||
# LAUNCH_COOLDOWN — Seconds to sleep between launching each parallel worker (default 0).
|
||
# Use 10–20 on memory-constrained hosts to stagger Godot init spikes
|
||
# so games never all peak-initialize simultaneously (prevents OOM crashes).
|
||
# SEED_OFFSET — Shift the seed range from [1..COUNT] to [1+OFFSET..COUNT+OFFSET]
|
||
# (default 0). Use for multi-sweep runs that share a parent
|
||
# results_dir and need disjoint seed numbers (e.g. Task #10
|
||
# AI_PIN_PERSONALITY rotation: 5× batches at offsets 0,10,20,30,40).
|
||
# REMOTE_BATCH_ROOT — Where remote autoplay batches write their output on the
|
||
# AUTOPLAY_HOST. Defaults to /tmp/@magic-civilization/builds
|
||
# so artifacts land OUTSIDE the remote host's dev working tree
|
||
# (writing into the working tree causes auto-commit divergence
|
||
# between hosts). Override to $REMOTE_HOME/... if the remote
|
||
# host is a pure build node without active development.
