Hello,
I just look at the scripts and trying to solve it.
Trying to understand some stuff.

First of all The main script "僵尸/javo" is collaborating with the script "WEAPON".
WEAPON can´t be deleted, otherwise the whole script doesn´t work
and game just crashes.
When we look into first script file
I was able to locate few of those opcodes.
I just can´t find these:

mov [esi], ebx
(I really don´t know what it is)

cmp [eax], 015AFA68 // all class
cmp [eax], 015AF0C8 // javo class
(These two or important, because they are responsible
for performing chosen animation by pressing TAB button)

mov [mydata+4], 2c7
mov [mydata+4], 2c1
(I would like to know what "mydata+4" represents.
also don´t know what 2c7 and 2c1 means.
I tried to find them through allocate memory -> assemle
but nothing found)

Then there is:
mov eax, [BH6.exe+146494C]
I have found it simply but then there is:
mov eax, [eax+128]
and eax, 0x200
cmp eax, 0x200
These I just can´t find them.

I´m spending more than half day to understand it and
wanna update it, but I need to know some of these stuffs.

How Can I find these to I could update my script?

When I tried to update is, the address "animation" shows correct values
but when I wanna perfrom the animation by pressing TAB button,
it just dont work and game crashes.
