    My Mood
    Tired
    A little bit of an update, I don't know if it works yet, my hack still crashes the game even if I just declare the correct addresses. Please let me know if it works for you.

    The point of this update it to make the function easier to C+P... since pretty much everyone uses the function with the prototype:

    Code:
    DWORD FindPattern(DWORD dwAddress,DWORD dwLen,BYTE *bMask,char *szMask)
    This is my method:

    Includes:

    Code:
    #include <Windows.h>
    #include <string.h>

    And the functions:


    Code:
    #define realAddy( cast, base, offset ) (cast)((DWORD)(base) + (DWORD)(offset))
    bool bExist(BYTE part, BYTE *whole, char *mask)
    {
    	BYTE *start = (BYTE*)(whole + sizeof(whole) - 1);
    	for(DWORD loc = 0; loc < sizeof(whole); loc++)
    		if((*(BYTE*)(start - loc) == part) || (*(mask + (strlen(mask) - 1) - loc) == '?')) return true;
    	return false;
    }
    DWORD lastLocationOfByte(BYTE part, BYTE *whole, char *mask)
    {
    	BYTE *start = (BYTE*)(whole + sizeof(whole) - 1);
    	for(DWORD loc = 0; loc < sizeof(whole); loc++)
    		if((*(BYTE*)(start - loc) == part) || (*(mask + (strlen(mask) - 1) - loc) == '?')) return (sizeof(whole) - loc);
    }
    DWORD FindPattern(DWORD first, DWORD total, BYTE *val, char *mask)
    {
    	size_t next = sizeof(*val);
    	BYTE *addy = (BYTE*)((val + next) - 1);
    	bool exist = false;
    	BYTE *loc;
    	for(DWORD n = (next - 1); n < total;)
    	{
    		DWORD spot;
    		for(spot = 0; (*(unsigned char*)(first + n - spot) == *(unsigned char*)(addy - spot)) || (*(mask + (strlen(mask) - 1) - spot) == '?'); spot++);
    		if(spot == next) return realAddy( DWORD, first, n );
    		else if(bExist(*(BYTE*)(first + n), val, mask))
    			n += lastLocationOfByte(*(BYTE*)(first + n), val, mask);
    		else n += next;
    	}
    	return false;
    }
