AI 11 - The Flycatcher (October 20)

Author File Description
File Details
Game Version: TAD
AI 11 - The Flycatcher

This AI builds mostly same as AI 10 - Horsemaster.

It is an improvement of the Horsemaster. It trains four unit types at a time. The point of making this AI is to make it more aggressive and support in team games. I also will try to make the lower difficulties a challenge.

AI is an all-rounded AI capable of several modes.

The AI works now alright for 30 Minute Treaty, especially on Age Maps or Jolly Maps.

If you've downloaded this file before, download again and replace the old with the new files.


New Flycatcher:

Update October 20:

- Aztecs train a bit less Arrow Knights and more War Hut Units. 

Update October 8:

- AI now uses 0.25 for Offense Bonus and 0.20 for Defense Bonus.

Update October 7: 

- AI has less Aggressive Values in a Defensive Reflex (0.25 instead of 0.35).

- AI no longer transports military units on Honshu and NR Honshu; this interfered with land gameplay.


New Flycatcher:

Update September 29: 

- AI now uses Fishing Boats correctly as I tested something in the previous version.


Update September 28:

- AI has more aggressive bonus values and less defensive values: Opportunity Attack increased to 0.3 (0.2), Opportunity Defense given 0.35 bonus for attack (0.15). This should help them focus on attacking armies and saving allies a bit less.

- British AI now uses Infinite Grenadiers Card instead of 3 Rockets. 

- Included August 11 Version in the Download


Update August 11:

- Added staggered resources savings for non-Treaty Games.

- AIs gather for 2 Town Centers in Fortress rather than 1.

- Added Handling for Naval Maps, including 20 Fishing Boat boom on water maps, and Transport Handling for NR Caribbean, NR Ceylon, NR Amazonia, NR Honshu and Island Polynesia. Expect naval invasions!

- Portuguese now research Econmedia Manor from Church card.

- British AI now always builds 2 Additional Town Centers.

- Maritime Maps also handled in AI script.

- Added Island Polynesia to Fishing Maps


- Update August 9: Improved German AI, Added new cards and handling for these cards. I did this after testing and trying out what I thought would be best.

- Changed Germans: Uhlans to 0.95, War Wagons to 0.79, enabled Mercenaries for Germans, 0.5 Bias Cav, 1.0 Native Bias for Germans (This means German AI can now do many more things and build a balanced army every game and beat other AIs).

- Removed Market from Europeans in Industrial and Asians in Imperial, priority 25 from 55.

- Changed 6 Infinite Grenadiers to Improved Grenades Card for British

- Changed 8 Richelieu's Regiment to Throughbreds Card for French

- Changed 6 Spahi to Irregulars for Ottomans

- Added Military Reforms for Dutch

- Added Siege Discipline for Iroquois

These Cards should appear in AI Decks in games with Homecity Level 100 or above.

- Version from July 27 included in Download


- Update July 27: Chinese no longer tries to build Light Infantry, only Banner Armies. Aztec AI trains more Jaguar Prowl Knights and less Coyote Runners.

- Update July 19: Aztecs Unit Priorities redefined. I have given Aztecs a Civ Bias of 0.5 BiasInf and 0.5 BiasCav (which also works for Light Infantry), and in addition extra Priorities for the Knight Units first, then War Hut Units second. This means that they will constantly train units while they have resources for them.

- All AIs can now make use of Light Infantry, not just Aztecs.

- AIs now use 10-20 units in training queue rather than 10-25.

- Update July 18: Aztecs train old priorities with General Units. AI uses 1 Building training as I found it bugged up the code previously. I had two values before: 10-25 units with 2 Buildings and 10-20 units with 1 Building. I now corrected this to 10-25 units with 1 Building for both of them.

- AI uses 85 Military Units in Industrial and 100 in Imperial (up from 80 Industrial, 110 Imperial; original was 70 Industrial, 90 Imperial).

- Aztec AI on account of less units in Imperial now again spawns Skull Knights when there is military population available; Sioux AI should also spawn Dog Soldiers.

- German AI trains more Skirmishers.

- Indians, Chinese, Japanese now have secondary and tertiary btOffenseDefense increased to 0.45 (up from 0.35); the normal value remains 0.50. This should prevent them from camping in their bases until very late game (1 hour).

- Version from July 3rd included in download


- Update 3 July 2021: 2 Building Unit Training once again.

- Update 2 July 2021: Military Units trained from 1 Building instead of 2 at a time, like in AI 9 - Big Daddy.

- Included Original Flycatcher in Download.

- Update 1 July 2021: Extra Market built in Imperial Age by Asians rather than Industrial; this should help Wonder Age ups to Imperial. It is still built in Industrial by Europeans and Natives.

- Update 5 May 2021: Original Flycatcher uploaded because of encountering online issues.

- Update 27 April 2021: French AI trains original values.


Things Different in AI:

- Rice Paddies can be build 5 distance (down from 8). Asians try to get an additional Rice Paddy in Imperial (up to 5).

- Maximum Army Unit count increased to 80 for Industrial (70) and 110 for Imperial (90).

- German AI trains more Dopplesoldners, Uhlans, less War Wagons and less Mercenaries, same amount of Skirmishers

- Japanese AI no longer tries to train Arsonists or Flaming Arrow Artillery (Arsonists are not classified as Mercenaries).

- AIs for Ottoman, Dutch, British, French, Spanish, Portuguese, German, Russians, have been made more aggressive (0.45, 0.50, 0.55)

- Turtle Up Rule increased to +0.8 so that Civs can eventually receive increased OffenseDefense while still being able to build walls and towers (up from +0.6).

I have uploaded a video which has screenshots of the AI playing online as an Ally for each Player:


Skim through the video and see what the AI can do!

On a test, the stock game AI on Hard got 535, 568, and 743 score on Tryhard Maps by 20 minutes; on the next test, the Flycatcher AI on Hard got 820, 900, 900 score on Tryhard Maps by 20 minutes. So, the improved AI is 50% better while upgrading its units. This is no superman test: the AI gets few unfair bonuses.

On a 4v4 on Tryhard Maps the Flycatcher AI got 800-900-1100 score by 20 minutes.

The Computer beat me at Ivory Silk Road where I thought there was a treaty period and he rushed me continually and whittled down my units and resources. And that's coming from me, a top 10 custom map player in Asian Dynasties.

Japanese Computer: 496 units killed
Portuguese Me: 250 units killed

Score: Compuuter 1200, Me 800, 20 minutes 50 seconds.

After finding out that there was no treaty, I decided to try and see if I could beat it on Hard rather than re-hosting the game with Treaty 20.

It beat me!

Him: 50000 unspent resources, Me 15000 unspent resources.

A fellow I played with described the AI script like this:

"It is Good, it plays like a real person."


"It is a good write."

"This long" (of game. It was a 2v2, 56 minute game).
