edit ok found the problem, it was my mouse_base, shouldn't deref it
ok im having trouble reading the correct value off the ptr+offset
can anyone tell me if this is correct?
| Code: |
mouse_base = *((int *) (*((unsigned long *) 0x892bf4) + 0x978));
mouse_x=*((int *) (*((unsigned long *) mouse_base) + 0x8c));
mouse_y=*((int *) (*((unsigned long *) mouse_base) + 0x90));
|
so basically i wanna see what value for the ingame mouse x and y coordinates are,
which is [[0x892bf4+0x978] +0x8c] for X and [0x892bf4+0x978] +0x90 ] for y.
but the value of the 3 var displayed are extremely large and offchart, nothing like xy coordinate value.
maybe something was wrong?
thank you for your help

| Maybe try to load the pointer using inline asm instead?

tried, was getting the same off chart values.
just wondering if the code above is correct.
if so, it must be the wrong offsets 8c and 90
cuz the [0x892bf4+0x978] is updated for sure

Based on the two things you wrote above, they don't match each other.
You said the base pointer would be (in C++):
| Code: | | mouse_base = *((int *) (*((unsigned long *) 0x892bf4) + 0x978)); |
And in ASM it was:
Which don't match each other. The C++ version would read the value of 0x892BF4, then add 0x978 to that and read again. Think you are going a bit overboard on the directions.
From what I see with the ASM code you want to add
0x892bf4+0x978 then read that value, then add the offset and read again.
What I would speculate it as:
| Code: | int mouse_x = *(int*)( (*(unsigned long*)(0x892BF4+0x978)) + 0x8c );
int mouse_x = *(int*)( (*(unsigned long*)(0x892BF4+0x978)) + 0x90 ); |
Can't guarantee that would be it since I dunno the code of the game and such. Good luck.

hmm
i always thought 978 was the offset for the mouse coord base ptr.
im not sure my self how it is working.
but in CE where u add pointers, i add 0x892bf4 as the address of pointer, 978 as offset , then add the 2nd pointer of the results with 8c as its 2nd offset.
so bascially the first one is mouse base pointer([0x892bf4+0x978]). with offset 8c and 90 being the x and y pointer.
so [[0x892bf4+0x978] +0x8c] for mouse X and [0x892bf4+0x978] +0x90 ] for y
maybe i was wrong with this terminology.

I have posted dynamic info in maple section. Here it is with source. It is dynamic pointers and shows how to read them.
And why use mouse pointers when you can use a point and call a function. No mouse pointers needed, ever.

1) The pointer is for the map not for the screen thats why use the pointer instead of "use a point and call a function" :)
2) Not at home anymore :s
When i get home i send you my function for pointer & Multi-Pointers reading :)

| Code: | __inline ULONG_PTR ReadPointer(ULONG_PTR* ulBase, INT nOffset){
if ( !IsBadReadPtr((VOID*)ulBase, sizeof(ULONG_PTR)) )
if ( !IsBadReadPtr((VOID*)((*(ULONG_PTR*)ulBase)+nOffset), sizeof(ULONG_PTR)) )
return *(ULONG_PTR*)((*(ULONG_PTR*)ulBase)+nOffset);
return 0;
} |
Probably better than yours Zorita.
You can also use this before you write to a value to make sure the value isn't void
Also make sure you use IsBadReadPtr on the base and base+offset or you will crash if the memory is not there. In maple this occurs on map changes, etc.

LOL how can you say its better then mine if you never saw any of my code?

I know all the other parts of your code were inferior from the disassembly
Just taking an educated guess

err i already saw your source few days ago. but i think u are mistaking the mouse x and y in your dynamic info with the ones im talking about?
they are totally different in coord as the one im using only shows the in game map coord with the mouse not outside the game. thats why im using the ptrs

You asked how to read a pointer which i gave generic examples and functions for

if you look at the code i showed in the first post, i know how to read the ptrs. but its just showing off charts value. i just wanna to make sure if my method for this double offsets are correct. if so, i must be using incorrect offset value.

if you still havent got it to work have you tryed dword? instead of int

what was the solution?
| Code: | char MouseBytes[17] = "\xA1\xF4\x2B\x89\x00\x53\x56\x8B\xF1\x8d\x88\x78\x09\x00\x00\x89";
dwMouseBase = *(DWORD*)dwFindPattern(dwAddress, dwLen, (BYTE*)MouseBytes, "xx????xxxxx????x", 1) + 0x978;
dwMouseX = ReadPointer((ULONG_PTR*)dwMouseBase, 0x8C);
dwMouseY = ReadPointer((ULONG_PTR*)dwMouseBase, 0x90);
SetDlgItemText(thisHwnd, IDC_MOUSEX, itoa(dwMouseX, buf, 10) );
SetDlgItemText(thisHwnd, IDC_MOUSEY, itoa(dwMouseY, buf, 10) );
|
That's my code. I've tried everything!
