Stats algorithm - Combat Magic

[Platonic]

Hi,

I would like to understand the algorithm that is used for stats in the game Combat Magic. Im taking the weapon "heavy cutlass".

So currently this is what i have:

1. Weight = float, as it is represented on screen. 3.9f

When i try to change the level, which is 15 in game.

the value is represented like this:

1,599,062,278D;1,599,062,280D;1B::9

If i edit the 1 bool to 0, the level will change to 1. I guess its a form of disabling the levels since the player starts at level 1.

If i edit the first byte of that dword value, "06h" to "07h" the level changes to 16.

1. 00h = 9
2. 01h = 10
3. 02h = 11
4. 03h = 12
5. 04h = 13
6. 05h = 14
7. 06h = 15 -- current level
8. 07h = 16
9. 08h = 1
10. 09h = 2
11. 0Ah = 3
12. 0Bh = 4
13. 0Ch = 5
14. 0Dh = 6
15. 0Eh = 7
16. 0Fh = 8
17. 10h = 25 -- suddenly level change
18. 11h = 26
19. 12h = 27
20. 13h = 28
21. 14h = 29
22. 15h = 30
23. 16h = 31
24. 17h = 32
25. 18h = 17 -- suddenly level change

...etc

So what is weird already is the jump to 25. If we just count normally from current level 15, 16, 17, 18, 19...etc and pretend like the jump from level 16 to level 1 never happened we would come out to level 25. So why levels whent back to normal sequence at hex 10h ? All i assume is that editing levels should happen in byte or word, Not in dword or other data types.

Help or explenation would be appreciated!

level = (first_dword_value XOR second_dword_value) + 1

this is hex and multiplication by 1.5, floored

maybe its xor or a type of byte encryption.

 

hex 0f in binary is 4 bits long

hex 10 in binary is 5 bits long

Thanks for the info, but i don't think that fully explains the algorithm, Found a pattern here which is perhaps interesting. You think it has any use?

When i subtract the first byte of the first dword with the first byte of the second dword value you keep getting the following sequence: 

 

1. 2
2. 2
3. 6
4. 6
5. 10
6. 10
7. 14
8. 14
9. -14
10. -14
11. -10
12. -10
13. -6
14. -6
15. -2
16. -2 
17. 2 -- repeat
18. 2
19. 6
20. 6

As if both values represent positive and negative. This sequence is static and appears contagiously. 

 

Im putting results in decimal though. I think makes most sense for read.

Thanks! Works well now!
