[Dev Tool] OOS Combat Simulator (Alpha)

[halo112358]

Here's an OOS combat test framework that I wrote, it sets up OOS combat in an un-observed sector and logs the result. There is no real user interface besides the script editor, if someone feels motivated to create something more useable please be my guest.

I intend this to be used by ship designers and mod developers to ensure that their ships are balanced both IS and OOS.

http://halo112358.googlepages.com/aa.hc ... mulator.7z

aa.h.combatsimulator.cmd is the initial script, edit this to set the ships given to each side - running this script will spawn the specified ships in a sector chosen at run time.

aa.h.combatsimulator.main is the body of the sim code - it spawns ships, assigns tasks and then waits for combat to resolve.

Once the sim is complete (one side wins) then all involved ships will be destroyed. All events are logged to log09876.txt. It's probably best to run the sim in an unknown sector (aka: empty sector) so that there isn't any interference.

let me know what you find if you do play with it

ps: If you pick 'null' as the sim sector you'll spawn the ships into the current [PLAYERSHIP] sector for IS combat simulation. This is useful for comparing OOS vs IS performance of a ship, it should highlight just how different OOS and IS combat really is (OOS an elephant wins against anything less than an M1/M2, IS it gets utterly owned by a given M6 or 3-5 M3's...)[/i]

re-use and derivation: do whatever you like with this code, have fun.

pps: you can learn all sorts of useless things by running this, like: Elephant > Hyperion

Code: Select all

(329052) START SECTOR (Unknown Sector)
(329052) ALPHA = ARRAY ( Kha'ak Hyperion )
(329052) BETA = ARRAY ( Xenon Elephant )
(329126) killer=(null)
(329126) Kha'ak Hyperion killed by Xenon Elephant(XTLSB-99) 1/1
(329126) END
(329126) h_1 fight took (74) seconds
(329126) h_2 Alpha lost (1) ships
(329126) h_3 Beta lost (0) ships
(329126) GC: destroyed 0 ships
(329126) GC: destroyed 1 ships

(329052) START SECTOR (Unknown Sector)
(329052) ALPHA = ARRAY ( Kha'ak Hyperion )
(329052) BETA = ARRAY ( Xenon Elephant )
(329101) THIS=(Xenon Elephant) attacker=(Kha'ak Hyperion) cmd=(0)
(329103) killer=(null)
(329103) Kha'ak Hyperion killed by Xenon Elephant(XTLSB-99) 1/1
(329103) END
(329103) h_1 fight took (51) seconds
(329103) h_2 Alpha lost (1) ships
(329103) h_3 Beta lost (0) ships
(329103) GC: destroyed 0 ships
(329103) GC: destroyed 1 ships

'.z7'? What format is that?


Would it be nice to know the state (shield/hull) of the winners at the end?

You can still open it with Winrar

Thanks Halo,

I just know this will be put to good use.

How did you resolve the $killer dilema?

The same way the autotrader does, it's best of the bad workarounds.

Code: Select all

skip if $killer -> exists
  $killer = [THIS] -> get attacker

Not that it really matters, but *.7z is 7-zip compression.

Really cool idea!

Jlehtone's comment about knowing state of survivvors' hull & shields is especially pertinent for 1-on-1 duels.

And I had absolutely no idea Hyperion gets iced 100% of time by an Elephant OOS. Who would've thought...

It should be possible to log the hull & shields of leftover ships when garbage collection occurs. I'll add that in if you guys are interested in it

Makes a little sense in hindsight as the Elephant with BPPCs is going to have much higher laser values.

[Hieronymos]

But considering Elephant's inferior laser energy (27,300/273), shielding (625Mj), shield recharge (4,700), manueverability (0.89%)--compared to Hyperion's...shows how badly the Dev's overcalculated the OOS combat power of the BPPC.

DDRS Rebalanced has an M6, the Paranid Achilles Gunboat, armed with 5x BPPC's in her front-fixed battery. Of course she lacks the weapons power to really use them properly (she's supposed to be a capship-hunter, but can't really cut it as such vs. M2's, even in larger numbers)..but it'd be interesting to see how she fares against an Elephant OOS. What I'd really like to see is an M7 class "Heavy Raider" with something like 4x GPPC's or 5-8x BPPC's in a fixed-front battery. With ~2Gj shielding, reasonable turn rate, and M7 class sized powerplant(s), she'd be a viable threat to M2's. IS anyway!..but I digress.

Again, your script is an excellent modding tool. And the victor's leftover hull/shield % are especially useful for 1-on-1 M2 and M1 duels., and variations thereof. When working the stats for Rebalanced, I did all those combat trials "by hand" the hard way.

A tidbit that I found during that time: vanilla M2's with GPPC's in their front turrets--instead of BPPC's--would win 1-on-1 IS duels against M2's with BPPC's up front ~90% of the time.

Thanks Again!

One BPPC would do 16,187 points of shield damage. Eight of them 129,496.

Shorter fight took 51 seconds. Three 1 GJ shields do recharge 38,142 points in 51 seconds (assuming they need to recharge right from start).

=> 3,038,142 kJ of shield will go down with 24 broadsides of 8 BPPC.

AHEPT: 1995, BHEPT: 4200
One 12 BHEPT + 6 AHEPT volley is thus 62,370.

Five 125 MJ recharge 191,173 points in 51 seconds. Total shield to kill: 816,173 kJ.

=> 13 hits from all guns of Hyperion should consume all shield that Elephant can have in 51 seconds.

In sector BPPC has worse rate of fire than HEPTs. Assuming fully equipped ships on both sides does not quite explain the result.

[Hieronymos]

I prefer to calculate shield and hull weapons damage output in terms of "damage per minute".
Thus:

BPPC=1,230k shield, 335k hull per minute.
BHEPT=890k shield, 148k hull.
AHEPT=564k shield, 93k hull.

Thus, Elephant's "Alphastrike" capacity is 9,840k shield/min, 2,680k/min.
While Hyperion's is 14,064k shield/min, 2,334k hull/min.

Elephant's vs. Hyperion's shield strength ratio is 4.8:1 in Hyperion's favor.
Even given max range of BPPC (5.1km.) vs. BHEPT (2.3km.), OOS combat result cannot be explained within a 51 second timeframe even with a 100% hit rate.

Another possibility is that the testing program didn't load Hyperion with all 3 1Gj shields.

Trying to use this script in a X3 2.5 with XTM configuration.
Does not work.
The oponents do not move.
Anybody has an idea of what's wrong ?

[Gqqnbig]

Doesn't work untill I change START to = in line 002 in aa.h.combatsimulator.attack.xml.

This is my modified version for AP Albion Prelude.
