 |
|
in an effort to try and improove some maple story hacks I wanted to use "if" and "else" so I could set a value to 1 and the hack would be on or set it to 0 and the hack would be off.
now I could just make a ggcrc but when you can just bypass that by applying the hacks before gg starts it just makes it easier.
so can you help me make an "if" and "else" in asm then once the game is running all I have to do is change the value from 1 to 0 with a program I make to turn hacks off without editing memory.

| Code: | cmp [somedword],1 // your switch
je dostuff
//here goes the else thing
jmp end
dostuff: // A label
// heres the if == 1
jmp end |
Or something? O_o I mean that include this code in every hack you're using, then just modify the value of somedword.
Related a bit: I've posted a guide how to do this with jump in game a long long time ago. You could try looking for it if you've time. I'm too lazy to find it :)

| Try a meso drop scrpt... You drop a # of mesos, then the script gets activated. Then drop another, and it gets deactivated. Or you could use if, else statements in a C++ DLL.

if it was a simple boolean check, why don't you just do
| Code: | cmp [somedword], 1
jne end
//if it equals put stuff here |

thanks for this.
i am planing on including this in all hacks so i can just turn them on and off without a ggcrc. hopefully I can get an external program to work but if not ill just use a dll.

GGCRC checks to see if any memory has been changed. No matter what method you use, GG will detect a change in the memory it scans.

Short answer: he wanted if-else. Longer answer: If you're codecaving and don't want anything modified, you've to run the code which you wrote over with your codecave jmp. Eg. Patching | Code: | DEADBEEF:
mov eax,edx
xor ecx,ecx
pop edx |
with | Code: | ccave:
cmp [somedword],1 // your switch
je dostuff
mov eax,edx // THESE ARE
xor ecx,ecx // THE BYTES
pop edx // WRITTEN OVER EARLIER.
jmp end
dostuff: // A label
// heres the if == 1
jmp end
DEADBEEF:
jmp ccave
end: |
Well.. If the over written byte code is used in both, if-else, then I'd be smart to write an epilogue (where the overwritten code is) and jmp to there from the cmp and dostuff.
