Sure I get that, but how do we end up on "that" specific addy?
That's all I want to know. Like I said I understand why we are at "001BA0" in the example by "timtraveller" its the line that holds the value. But my question was how to get the "3" as we are told value for "Crash Depth" is at "1BA3"

This is from "timetravellers" tut, just to make it more clear as to what I am talking about.

1BA0 = 74
1BA1 = 68
1BA2 = 00
1BA3 = 66

and so forth

I strongly suggest downloading my modding tools pack. In it is a hex editor called XVI32 that does all the numbers figuring for you when you click on each hex address. It's called 'Data Inspector' in the hex editor options menu. It will show singles, longs, integers, etc. Really convenient. Hope this helps. ;)

@NVDRIFTER

I see we play with the same toys.
:rotfl:

Trying to figure out the numbers myself makes my head hurt. :dead: :rotfl:

Ahhhh SUPER thanks a bunch man! I am at work atm, but I have the game installed here for "testing purposes" :p I will have a look at lunch time. Thanks again man!:up:

Hex value and converting this to Decimal?

I see in the Sim file the item for "Min" may have a value of 803F in hex but this = 1 via the analyzer in decimal, how is the conversion done? as i see this value could be 0.1 say which is CDCCCC3D and -1 is 80BF.

How is this worked out?

It is a format that is used to store large numbers. IEEE 754 Floating Point Single. It is not the exact thing taught in school, more computer science. It stores the mantissa and exponent and sign as a format. You can study the why and how they get it mathematical theory, real pain in the ass. Use a calculator such as this one. Plus remember the numbers are entered in backwards.

Enter the raw 00 00 80 3F from the hex file as 3F800000 gives you value 1.

Above CaptainCox wanted the crash depth. It looks like this 66 e6 ac 43 in file color yellow.

Enter backwards 43 ac e6 66 two bytes at a time 43ace666. Gives =345.79998779296875 ~rounds to 346 in game.

Negative numbers are stores as the 9's complement. See -1 is 80BF--> BF80 The normal 1 is a '3' there so (F-1)-3 = B. Something like that...:/ 11011 is 00100 computer must use binary and makes it add. IE Subtraction is adding the 9's complemnt in binary. Fast because all 1 are 0 transposed. then remove 1 bit. Darn 24 years ago to remember that stuff.

Cheers "Jungman". My problem now is how to actually find stuff. I asked in this thread http://www.subsim.com/radioroom/show...587#post511587
I am sort of in Limbo at the mo with this one...

Thanks heaps Jungman :know: will have a look into.. Too much fun...

Have a great day :)

:yep: Danke! Nvdrifter I found an extra set of data points for the fast mark 14 inside the torpedo_US.sim file. Can you add this:

Mark 14 Torpedo .sim Tweak File .txt

[1]
DropDownName=Mark 14 Main
absolute,byte,7FC,type
absolute,single,80A,depth
absolute,single,821,max_dive_angle
absolute,single,883,max_turn_angle
absolute,single,8A2,impulse
absolute,single,83E,speed ---->slow_speed
absolute,single,86C,range ----> fast_range

absolute,single,85E,fast_speed --> add new
absolute,single,84C,slow_range --> add new

Thanks for making these tweak files, alot of work!:up: For readability just copy paste this:
