Thanks, but i already solved this problem. 
Hello, i searched the entire day for a solution and did not find anything, so i need your help.
I started 'learning' AA Script coding (and assembler) a few days ago and i do not get the whole registers stuff.
i have read samuri25404's guide 'A Very In Depth Tutorial on Auto Assembler'
which explains the use of EAX/AX and so on very well, but it does not explains how to use your 'own registers' to store information in a way i can understand, so i hope you can clarify and explain it a bit more.
Here is an example:
I want to change the durability (which is stored as int32 (4 bytes)) of an item to 100%.
To achieve this i subtract 100, stored in my own register, by the current durability to get the missing percent.
My problem is, that if i want to save my script (press ok) there are compiler errors:
| Code: | | Not all code is injectable. (Error in line 18 (sub 00000000,[ecx+1C]): This instruction can't be compiled) |
I know that this is caused, because i want to access an empty register/variable (whatever this is called)
So obviously it is my own register, which causes this error and i guess it just pointing to the 'null'-address, right? (unassigned pointer?)
But i don't get what i have done wrong, i hope you can explain this whole 'own register'-stuff to me.
My code example:
| Code: | [ENABLE]
//code from here to '[DISABLE]' will be used to enable the cheat
alloc(newmem,2048)
label(returnhere)
label(originalcode)
label(exit)
registersymbol(durability)
alloc(durability,4)
newmem: //this is allocated memory, you have read,write,execute access
//place your code here
originalcode:
//own code
mov [durability],64 //set durability variable to 100 (64 in hex)
sub durability,[ecx+1C] //subtract the current durability from the 100
mov [esp+04],durability //store the missing durability to 100%, to the address, which will be used to apply durability lose
//original code
mov edx,[esp+04] //The game puts the durability lose to the register 'edx'
push esi //doesn't matter for me, but cheat engine copied it in here
exit:
jmp returnhere
"unepic.exe"+20305:
jmp newmem
returnhere:
[DISABLE]
//code from here till the end of the code will be used to disable the cheat
unregistersymbol(durability)
dealloc(newmem)
dealloc(durability)
"unepic.exe"+20305:
mov edx,[esp+04]
push esi
//Alt: db 8B 54 24 04 56 |
Thanks in advance
