                }
            }
        }
    }
}

IsValidTarget is just ( TargetPlayer->bManAlive)&&(!TargetPlayer->bManDown ) && (TargetPlayer->soldierinfo ) && ( TargetPlayer->playerinfo->ptr ) && ( TargetPlayer->soldierinfo->ptr )

there is small calculation done for getting text centered based on taken bonepos, also there is ESP Fade effect (thanks tetsuo). You can also easily add boundingboxes wich are via bonepos just use ur imagination and see how name and distance esp are done.

whats this ?

if ( strcmp ( TargetPlayer->szPlayerName.c_str(), gLocalPlayer->szPlayerName.c_str() ) == 0 )
continue;

above code prevents esp drawn to localplayer...

+ uc-forum in general and ppl here who contributes their knowledge

enjoy

o: thanks for the contribution

I think it may be a better post with actually knowing what newworldtoscreen is


i could do the same


if(player[i]->Team != Local->Team){

WORLDTOSCREENBISHES(out,in,in);

}


where
\

this would be kinda better still not good but u get the drift

if(player[i]->Team != Local->Team){

:3DXVec3TransformCoord(&vec3,&origin,&WorldViewProj);


vec2.x = vp.width / 2 * vec3.x;
////etc

}

[Jugga]

__declspec(naked) bool CEntity::NewWorldToScreen(D3DXVECTOR3* pVecInOut)
{
    _asm mov ecx, cTextWriter;
    _asm jmp [ g_dwWorldToScreen ];
}

[Sfab1]

oh yes

and in global updates

init it

HMODULE renddx9 = GetModuleHandle( "RendDx9.dll" );

g_dwWorldToScreenNew = FindPattern( (( DWORD ) renddx9 ) + 0x80000, 0x20000, ( PBYTE )"\x55\x8B\xEC\x81\xEC\x00\x00\x00\x00\x8B\xD\x00\x00\x00\x00\x8B\x1\x56\x57\xFF\x50\x00\x8B\xF0\x8B\x16\x8B\xCE\xFF\x52\x00\xD9\x40", "xxxxx????xx????xxxxxx?xxxxxxxx?xx" );
