[PetraAI] Attacks occur later

[Langbart]

A user named marder reported via IRC 0ad-dev ​12/Nov/21 that he observed a different behavior with the PetraAI, the attacks occur later than usual.

11:25 < marder> hey, did something change about the AI behavior in svn?
11:26 < marder> if I remember correctly very hard aggressive petra used to rush around minute 7
11:26 < marder> but when I play now in svn that doesn't happen until 15 min (or even later) in
11:27 < marder> in the last games I played regardless of the map petra never tried to rush
11:28 < marder> and this makes it much easier to beat the ai

Testing the AI on a map called the_limes_2p from the ​community-maps-2 mod.

the_limes_2p

Autostart command

~/0ad/binaries/system/pyrogenesis -quickstart -conf=mod.enabledmods:"mod public community-maps-2" -autostart="scenarios/the_limes_2p" -autostart-ai=3:petra -autostart-aidiff=3:5

Up to [25875], the attack from the AI (green player) always occurred around the 10-minute mark; with [25876], the AI is more hesitant and puts its resources into building towers rather than attacking.

third_macedonian_war

Autostart command

~/0ad/binaries/system/pyrogenesis -quickstart -conf=mod.enabledmods:"mod public" -autostart="scenarios/third_macedonian_war" -autostart-ai=2:petra -autostart-aidiff=2:5 -autostart-ai=3:petra -autostart-aidiff=3:5

Could you please check the values of the personality, e.g. remove

	if (this.debug < 2)
		return;

from PetraAIs config.js.setConfig()?

Replying to Freagarach:

I changed the line, like you can see below: ai/petra/config.js ​L278

Line
277	if (this.difficulty < 2)
278	this.Economy.workPhase3 = Infinity; // prevent the phasing to city phase
279
280	API3.warn(" >>> Petra bot: personality = " + uneval(this.personality));
281	};

The values did not change
