Die Uhr des Hosts wartet jetzt auf den Gast. So kann ein langsamer Start des zweiten Prozesses die Takte bis zum Vergleich nicht mehr verbrauchen. Der Bot endet auch dann, wenn er seinen Bericht nicht schreiben kann, und überlebt den Test nie. Ein leeres --storage= führt ihn nicht mehr in den Ordner des Spielers. Ein neuer Test prüft, dass der Bot ohne schreibbaren Bericht mit Exit-Code 1 endet. Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>

## A second instance of the game for the test of two instances. It starts the
|
|
## real main scene as a guest, hits the rock beside the spawn clearing until
|
|
## it has a stone, follows the host until the host stops at a tick, and
|
|
## writes what its world looks like then as JSON.
|
|
##
|
|
## The test of two instances starts it; by hand:
|
|
## godot --headless --path game -s res://tools/guest_bot.gd -- --join=ADDRESS
|
|
## --storage=FOLDER --until=TICK --out=FILE
|
|
|
|
## Milliseconds the bot waits for everything before it gives up.
