Computing sub crush depth!

[NEON DEON]

Crush depth.

Webster pointed out to me that maxdepth in the sub cfg file enables crush depth.

Well yes and no,

It would appear that both max depth in the sub cfg file and the crash depth in the zone file combine to define crush depth.

First off looking at the S-18:

Max depth in sub cfg file is listed as 61 meters.

Crash depth in sub zone file is 122 meters. (this is not crash depth in cfg file and has nothing to do with that).

The crash depth is 100% deeper than max depth.

Taking the S-18 down to 120 meters sinks the sub in a few minutes. However, taking her down past 61 meters and starting the clock ticking it takes the S-18 when leveling off at 90 meters about 8 1/2 minutes to crack open. but if you level off at 85 meters some 24 meters(not feet) below max depth she does not crush. That is 40% lower than maxdepth.

The Porpoise:

Max depth in sub cfg file is 100 meters.

Crash depth in sub zone file is 150 meters.

The crash depth is 50 % deeper than max depth.

Taking the Porpoise down to 140 meters 40 % below max depth the sub sinks.

However, adjust the zone crash depth to 200 meters 100 % more than the max depth in the cfg file like the S-18 and the sub stays intact at 140 meters. See picture below where the sub ran at 140 meters for over 9 hours.




So when you leave the max depth of the porpoise at 100 meters in cfg file you can adjust the crush depth by varying the crash depth in the zone file

IE:

100M max depth and 200M crash depth = Crush depth below 140 meters
100M max depth and 175M crash depth = Crush depth below 123 meters
100M max depth and 150M crash depth = Crush depth below 106 meters
100M max depth and 125M crash depth = Crush depth below 89 meters! Thats under the max depth reading.

So long story short, a crush depth set 100 % below max depth will yield crush depth of maxdepth * 1.40. Well at least thats my theory.

This is in 1.4 version. but,in 1.5, I would bet that if you set max depth on the playable uboat to 100 M and crash depth in the zone file to 200 M she will crack open after 140 meters

Of course, they could have changed how they did crush depth in 1.5 too.

ok, here is where i think your getting things mixed up.

there is one crashdepth in the subs cfg file that means one thing and there is another crashdepth in the subs zon file that stands for something completely different but they have the same name so its easy to get confused.

the crashdepth in the cfg file is the depth the sub goes to during an emergency dive. its a preset depth that isnt too shallow and isnt too deep, its just an evasive manuver. (hit the "c" key)

the crashdepth in the subs zon file stands for the subs "crush" depth and the value under it is the speed at which you implode. i dont know if that 2.0 setting is 2 minutes or 2 seconds but its how long you are at crush depth before you pop.

look at what the subs specifications are and look at how the stock file values are set and that will help you see what is what.

but when you talk about changing the crashdepth setting you have to specify which crashdepth file you are changing because they are totally different but have the same name.

i hope this clears things up a little for you. the more you understand this game and how the files can confuse you the more you

Hi Webster,

Look at the above post again.

I explained on line 7 in my post where the crash depth was it was in the zone file. The reason why I called it that is that is what it is called in the editor. I also qualified myself in that same line that it had nothing to do with crash depth in the sub cfg file.

Crush depth listed as crash depth in the zone file works in combination with the max depth in CFG file to determine where your boat will fall apart given enough time.

Go below crush depth will give you damage to the boat that is hidden but you can still recover if you move fast enough.

Ok well I ignored the ratio in my first post observations.

Turns out that max depth does not have a bearing on the boat taking damage.

The formula is a lot less complicated then that.

The point at which you start taking hidden damage is 70 % of crush depth listed as crash depth in the subs zone file.

Which means with no damage to the boat from other things like depth charges, bombs, etc, etc, then You should be able to list your red line in the max depth to 70 % of the crush depth and be ok.

The config file basically an eye candy file and a reference point for the menu buttons. I found that out when I was setting the submarine drafts to match the pictures of subs. Not being the sharpest pencil in the box, I played with the surface depth for a long time before I realized it only affected the depth the sub came to when the surface button was used. No matter how small you make the number the sub will not come farther than the draft allows.

lots of stuff in there does things, the speed settings decide how the engines power ratios are done in the game.

the max depth setting will tell the game where to put the red needle on the depth guage. now the sub seams to stop going below that needle but i dont know if its the needle its working off of to do that or if its the cfg number.

im not sure but i think it also renders the ships size based on the cfg numbers but i never really checked that but just to be safe i made sure the numbers were accurate anyway.

and also some stuff in it does absolutely nothing like you said so its a mixed bag

i found some early work done on this topic and it can be very informative

itss CCIPs post and a mod he did called "increased crush depths"

i bumped it to the top of the forum for you

I took the S-18 for spin today and got her to 125 meters.

I set the dive to 133 meters and when she past the stated crush depth of 122 I blew the tanks. glass was breaking and crewmen were fixing god knows what but she made it to the surface. Checked the damage screen which listed 0 damage. Then I took her to max operating depth of 85 meters. Hidden damage kicked in and she could not hold the depth and sank. So my theory is the clock starts ticking damage wise once you go below max operating depth and crush depth does not crush you.

I equate max operating depth to 70% of stated crash depth in the zone file.

As far as what is crush depth goes, Odds are you will sink before you crush. IE. the force exerted on the hull is so great that it pops a hatch or two or all of em and the boat sinks and never really crushes.

Anyways thats my story and I am sticking to it.

yes crushing stops the split second the hull breaches because the pressure instantly equalizes and thats what kills you, the instant pressure change

well i hope you get this all sorted out because it looks good so far.

as for sinking from flooding and not crushing, have you tried testing 0.01 for crush time or maybe 0.001?

any leak at that depth should be like a dam bursting so its like instant death from the pressure change before you know the waters even coming in (history channel lol)

i wonder if you could do an end run by adding a controller that maxed out your hit points when crush depth is triggered?

Good idea about the damage speed. I ll test that next.

So what would happen if you set surface ships crush depth deeper and crush damage slower? Would that alone cause ships to sink slower?

not sure how that would work because its not underwater and any setting that shallow might get problems in rough seas likes ships sinking by themselves


as for controlling the sinking of ships im told the key to sink ships is how you control flooding times for each zone, but then you get into ships with messed up and missing damage zones and that a whole new headache lol

what are you basing your data on to figure the "safe" max depth without sustaining any damage

i mean what numbers are you saying "this is where it should be"


because all i could find was crush depths and test depths but test depths arent the max safe depth the sub to do because rated test depths are way too shallow

if thats what the subs are supposed to do then all the subs in the game already go way too deep because it would put max depth for most of the fleet subs at 250ft

I really hate the UBI damage thing!

either you crush or you don't there's no "time limit"

hmm I hope the time thing gets axed...

all i get is hull damage around 15-20 feet before crush depth then the cascade falure starts

if i get slow build up of hull damage then i get no accurate crush depths so it definately tricky
