Code:
//-------------------------------------------------------
ok my tutorial on the UE3 for apb by the1domo @ The Defaced
//-------------------------------------------------------
FColor MakeColor(int R, int G, int B, int A)
{
FColor ReturnedColor;
ReturnedColor.R = R;
ReturnedColor.G = G;
ReturnedColor.B = B;
ReturnedColor.A = A;
return ReturnedColor;
}
//-------------------------------------------------------
FColor Green = MakeColor(0,255,0,255);
FColor Red = MakeColor(255,0,0,255);
//-------------------------------------------------------
you need to define PI and URotationToRadians
//-------------------------------------------------------
#define PI 3.1415926
#define URotationToRadians PI / 32768
//-------------------------------------------------------
Heres some stuff from the SDK you need for apb
//-------------------------------------------------------
APlayerController* pPC = NULL;
APlayerController* PlayerController = NULL;
APlayerController* MPC = NULL;
UObject* pCallObject = NULL;
AcAPBPlayerController* pPlayerController = NULL;
FVector MyCameraLocation = FVector();
FRotator MyCameraRotation = FRotator();
//-------------------------------------------------------
you need this to get all of your pointers Credits go to uNrEaL
//-------------------------------------------------------
UObject* GetInstanceOf ( UClass* Class )
{
static UObject* ObjectInstance;
ObjectInstance = NULL;
for ( int i = 0; i < UObject::GObjObjects()->Count; ++i )
{
UObject* CheckObject = ( *UObject::GObjObjects() )( i );
if ( CheckObject && CheckObject->IsA( Class ) )
{
if ( !strstr( CheckObject->GetFullName(), "Default" ) )
ObjectInstance = CheckObject;
}
}
return ObjectInstance;
};
//-------------------------------------------------------
to get the Size of a FVector
//-------------------------------------------------------
float Size (FVector &v)
{
return sqrt(v.X*v.X + v.Y*v.Y + v.Z*v.Z);
}
//-------------------------------------------------------
Normalize is a vector
//-------------------------------------------------------
void Normalize (FVector &v)
{
float size = Size(v);
if ( !size )
{
v.x = v.y = v.z = 1;
}
else
{
v.x /= size;
v.y /= size;
v.z /= size;
}
}
//-------------------------------------------------------
ok use thie to get GetAxes
//-------------------------------------------------------
void inline GetAxes (FRotator R, FVector &X, FVector &Y, FVector &Z)
{
X = RotToVec(R);
X.Normalize();
R.Yaw += 16384;
FRotator R2 = R;
R2.Pitch = 0.f;
Y = RotToVec(R2);
Y.Normalize();
Y.Z = 0.f;
R.Yaw -= 16384;
R.Pitch += 16384;
Z = RotToVec(R);
Z.Normalize();
}
//-------------------------------------------------------
you need this to use WorldToScreen and Draw Boxs
//-------------------------------------------------------
float inline Dot (const FVector& V1,const FVector& V2)
{
return ( V1.X*V2.X + V1.Y*V2.Y + V1.Z*V2.Z );
}
//-------------------------------------------------------

//-------------------------------------------------------
WorldToScreen is wot you uses to Draw on the Screen
//-------------------------------------------------------
FVector WorldToScreen (UCanvas* Canvas, FVector WorldLocation)//Helios
{
FVector X,Y,Z,D,Out;
GetAxes(MyCameraRotation,X,Y,Z);
//D = WorldLocation - MyCameraLocation;
D.X = WorldLocation.X - MyCameraLocation.X;
D.Y = WorldLocation.Y - MyCameraLocation.Y;
D.Z = WorldLocation.Z - MyCameraLocation.Z;
Out.X = (Canvas->ClipX/2)+( Dot(D,Y))*((Canvas->ClipX/2)/tan(Me->FovAngle*PI/360))/Dot(D,X);
Out.Y = (Canvas->ClipY/2)+(-Dot(D,Z))*((Canvas->ClipX/2)/tan(Me->FovAngle*PI/360))/Dot(D,X);
Out.Z = 0;
return Out;
}

ok it is my Draw Box ESP Credits to SystemFiles for help me fix it
you use it to Draw Boxs on the Screen
//-------------------------------------------------------
inline void DrawBoundingBox (UCanvas* Canvas, APawn* Target)
{
FVector X,Y,Z,D,E,top,bottom;;
float width, Left, Right, Top, Bot;

return;

top = Target->Location;
top = WorldToScreen(Canvas,top);

//-------------------------------------------------------
how we need to itert tho the Player list
//-------------------------------------------------------
void DrawPlayerESP( UCanvas* pCanvas )

//-------------------------------------------------------
PostRender is your main thread
//-------------------------------------------------------

pPlayerController->GetPlayerViewPoint( &MyCameraLocation, &MyCameraRotation );

}
}
//-------------------------------------------------------
your hook Function you need it to get the Canvas and pCallObject for the hook Credits go to uNrEaL
//-------------------------------------------------------
void hkProcessEvent ( UFunction* pFunction, void* pParms, void* pResult )
{
_asm pushad;w
_asm mov pCallObject, ecx;

{

}
}
}
_asm popad;

}
//-------------------------------------------------------
your Detour Function for the hack
//-------------------------------------------------------
void OnAttach ()
{
pProcessEvent = ( tProcessEvent )DetourFunction( ( PBYTE )ProcessEvent, ( PBYTE )hkProcessEvent );
}
//-------------------------------------------------------
DllMain you need this for the dll
//-------------------------------------------------------
BOOL WINAPI DllMain ( HMODULE hModule, DWORD dwReason, LPVOID lpReserved )
{
if ( dwReason == DLL_PROCESS_ATTACH )
OnAttach ();
return TRUE;
}
