Help me find more/pattern to values

[NoFear]

Please, need help with determining how values are converted. Here is a list of values in game and the Dword value of it:

10        1076101120

7458   1086136832

7468   1086139392

7478   1086141952

 

2978   1084703680

3056   1084743680

3234   1084834816

3254   1084845056

3289   1084862976

3299   1084868096

3309   1084873216

3334  1084886016

3354   1084896256

 

15492   1087259136

15570   1087269120

 

 

Hopefully @Enyby you can help me

Same value. It is impossible.

[NoFear]

Lol. Typo.  3289 is 1084862976

[Enyby]

Need more data from continuos range. 0-20 would be perfect.

[NoFear]

I'll try. Sorta difficult to obtain a value I want. 

 

Edit: 

Game is I Love Coffee.  It is by Line.

[Enyby]

And power of 2: 2 4 8 16 32 64 and so on

[NoFear]

See what I can do for you.  

[Enyby]

Look like sorted bits from source number and some xor at the end.

But not all data fit this theory. Need check - may be present some mistakes.

[NoFear]

Counting up from 1

1072693248

1073741824

1074266112

1074790400

1075052544

1075314688

1075576832

1075838976

1075970048

1076101120

1076232192

1076363264

1076494336

1076625408

1076887552

1076953088

1077018624

1077084160

1077149696

1077215232

1077280768

1077346304

 

Values 1 through 23. If something doesn't seem right, I could've mistyped... 

[Enyby]

Answer: same as previous is double.

double - double hex - first 32 bit as dword.

10 = 4024000000000000 1076101120

         for (int j: arr) {
             long l = Double.doubleToLongBits((double)j);
             System.out.println(j + " = " + Long.toHexString(l) + " " + ((int)(l >> 32)));
         }

How do you know this and figure this out? You are talented! 

[Enyby]

Many tries with script, xor, compare values in different way. In the end I noticed similar look up as previous task. I check and all worked.

[Enyby]

Usually cifer worked with xor - this is very comfortable for this operation. Because xor A twice got same number.

And some shift: to left, to right or cyclic shift.

Of course can be another biwise operators - and, or, not but it rarely.

 

First step in any investigation - write source and destination in bit form and compare visually.

Another step - compare changes from similar numbers and how it changes reflect in destination.

Next steps dependent on getted results.

ikr, maybe he/she can create dedicated thread to find pattern
