MW3 UAV Memory Patch

Zitat von cardoow

Well since the radar is drawn locally you can manipulate it like a boss, saw people draw their own radar + use rotatedpic, but i personally like to use the engine to achieve my wishes. So since its almost christmas i have some Advanced UAV code for you guys.

this function does it all

  void __cdecl sub_47F690(int a1, int a2, int a3, int a4, int a5)

it loops trough a struct of 18 big, as far as i know its not clientinfo or entity, feel free to reverse it

  v7 = (char *)&unk_8F2938 + 3640 * a1;
    v52 = 18;
    do
    {
      .....
      v7 += 140; [COLOR=Red]//see here the struct size = 0x8C = 140 dec[/COLOR]
    }
    while ( v52-- != 1 );
 
 

now we're heading to some more important stuff
at the bottom of the function we see a call to drawrotatedpic

   sub_40D420(v51, v55, v56, v48, v47, *(_BYTE *)(a4 + 16), *(_BYTE *)(a4 + 17), v44, (int)&v58, v31);

and we see that v31 holds the shader.

if we scroll up a bit we see this piece of code

   if ( dword_8FF284 || v10 ) [COLOR=Red]// 0x8FF080 is cg_t, means cg_t + 0x204 holds the advanced uav value[/COLOR]
{
    if ( !v45 || !dword_A041F8 || (v31 = dword_A041F8, sub_4F5920(dword_A041F8)) )
    v31 = dword_A04184; [COLOR=Red]// here v31 will hold compassping_enemyfacingdirection[/COLOR]
}
 

so we now know where to toggle the advanced uav, but now we only see the shaders when people shoot. We want those shaders at all time.
Now if we take a look at the top of the function we will find this

  if ( v7[56] & 1 )[COLOR=Red]//guess here they check for isalive[/COLOR]
      {
        v8 = *((_DWORD *)v7 + 16);
        v10 = (unsigned __int16)((_WORD)v8 >> 16);
        v9 = (*((_DWORD *)v7 + 16) >> 17) & 1;
        if ( v43 || v9 || (_WORD)v8 >> 16 || (unsigned __int16)(v8 & 0x8000) ) 
        {
          [COLOR=Red]//we need to make sure this if is true[/COLOR]
          [COLOR=Red]//we can do hard stuff with shifts or bitwise ands, or just take the easy way and pick v43[/COLOR]
          v12 = dword_96A1DC;
          v11 = 1;
          if ( *(_DWORD *)v7 > LODWORD(dword_96A1DC) )
            *(_DWORD *)v7 = 0;
          if ( *(_DWORD *)v7 < LODWORD(v12) - 500 )
            goto LABEL_71;
        }
        else
        {
          v11 = 0;
        }
 

if we look something above that code we will find this

   v43 = *(_BYTE *)(dword_1C2C39C + 12);

hey! that looks like a cvar! + 0xC is the value, hmm lets make it have a value! (this is g_compassShowEnemies)

  void AdvancedUAV()
{    
    cg_t->uav = 1;    [COLOR=Red]//the 0x8FF284 we found before in cg_t[/COLOR]
    *(BYTE*)(*(DWORD*)(0x1C2C39C) + 0xC) = 1;    [COLOR=Red]// the cvar[/COLOR]        
}

call this every frame and you will have advanced uav at all time, have fun!
