Benchmark test: AI's "SHIP SPOTTED" and TC
 

I decided to look into the effects that weather, time of day and time compression have on SH3's AI crew's ability to spot a target versus the range to target once SH3 has dropped straight back down to 1x TC.

I created 4 simple missions. The date for all 4 is set to January 1, 1943. All 4 missions are the same except for their time of day and weather conditions. Two of the missions take place at 00:00 - midnight. One of these missions has the weather set for as clear as possible. The other mission has the weather set for as foggy and rainy as possible.

Similarly, the remaining 2 missions have the same weather extremes but both missions have their time set for 12:00 - midday.

In all of the missions, the player's type VIIC UBoat's waypoint cuts right through the path of a stationary C3 merchant ship some 25km or so due south. Also, the UBoat's AI crew is defined in all missions as being "ELITE", the highest possible level.

Immediately upon each mission's start, I would set the UBoat's speed to ahead flank on surface, meaning it would travel at 18-19kph. The watch officer was always present in his tower position.

I played each mission 4 times, at the following time compression speeds: 1x, 256x, 1024x and 2048x. My SH3 configuration is set up so that when a ship is spotted, time compression automatically drops back down to 1x.

My SH3 installation is patched to version 1.4b. It includes several mods that may possibly affect the outcome of these benchmark tests, though I believe that the results would be similar for someone running SH3 v1.4b without any mods.

Here are the results, showing the UBoat's approximate distance from the ship spotted under the various scenarios. The distance to ship spotted was determined by switching to Uzo view immediately after receiving the AI's "SHIP SPOTTED" message.

Could you please use the same test, however remove all the bad weather effects in basif cfg as below as I have a slight hunch that not all is correct here.

Please do me a favor. It took me ages to run these tests. I've provided a link above, from where you can download the 4 missions.

Install them, run the tests you want and share your results with us here. :yep:

It was worth a try :rotfl: :rotfl: :rotfl: :rotfl: :rotfl: :rotfl:

Ok I will do my own test :up:

Yar Kapitan! I spot bullsh*t off the port bow! I hate TC.

Thank you Avon, I used to do tests like this in SH2, it does take many hours I know. Some tests I did proved fruitless after going in and out of the sim tweaking this and that, some turned up a gem.
If it wasn't for modders and tests like this we would be stuck with buggy games. :up:

great :roll: so now I have to sit at my computer for 7 days straight in order not to be spotted in an appropriate amount of time to dive, or whatever.

now the question is, how to adjust the script so that the distances for spotting goes up.

I apologize to the true sims out there who are offended by my request, I'm a arcade-type who relies on TC to accomplish at least 1 mission in a sitting

looks like another mod coming into formation

Sounds like some good information. Thanks, Avon!

Yeah, it seems like we can smell a mod from miles away... :lol:



Great test, by the way. And by using your very useful data, I have composed a very practical 'Kaleun Haiku'. Here goes:

TC is okay
sailing in the day
but TC at night
will give you a fright!


:lol: :lol: :lol:

:rotfl: :rotfl: :rotfl: :rotfl: HAIKU :rotfl: :rotfl: :rotfl:

Excellent work!

Think that is a rhyming couplet, a haiku goes 5 syllables/7 syllables/5 syllables e.g.

Compression too fast
Watchman does not see the ship
You are dead again

whoops, i forgot the definition of a haiku. Thanks!

Who knew that Silent Hunter 3 could be so poetic??? :lol:

Let me try!

Brit ports are red.
French ports are blue.
AI is to TC
Like bureaucrats to glue.

:P
