[Question] Drawing issues... again -.-

[-Ryuk-]

Hey guys,

Once again, I need drawing to help me debug my bot. However I am having trouble getting it to work.

Im struggling to updated my CameraInfo Struct...

    public struct CameraInfo    {
        public uint unk_0;
        public int int_0;
        public Vector3 Position;
        public Matrix3 Matrix;
        public float FieldOfView;
        public uint unk_1;
        public int Timestamp;
        public float NearZ;
        public float FarZ;
        public float Aspect;
}

To get the "ActiveCamera" I am doing:

GeneralHelper.Magic.Read(GeneralHelper.Magic.Read(Offsets.Drawing.WorldFrame) +Offsets.Drawing.ActiveCamera);


internal static uint WorldFrame = 0xC6C1E4;
internal static uint ActiveCamera = 0x80D0;

According to the WoWFunction GetActiveCamera, the above addresses are correct.

Using the struct I have I get:


The Matrix, FoV and Position seem correct, the rest are wrong.

Any Ideas?

inline CMatrix44 GetWorldMatrix()
{ return CMatrix44::Identity; }

CMatrix44 GetProjectionMatrix()
{
	SCameraInfo *pCamera = GetActiveCamera();
	Delegates::CGCamera__FOV_t pGetFieldOfView = reinterpret_cast<Delegates::CGCamera__FOV_t>
		( Process::GetVirtualMethod( (DWORD_PTR) pCamera, Offsets::VirtualMethods::Camera_FOV ) );

	float fFieldOfView = pGetFieldOfView( pCamera ) * 0.6f;
	float fNearClip = Delegates::World__GetNearClip();
	float fFarClip = Delegates::World__GetFarClip();
	float fAspect = Process::GetMemory<float>( Offsets::General::Camera_AspectRatio );
	float fYScale = 1 / tanf( fFieldOfView / 2 ); // take care of division-by-zero!
	float fXScale = fYScale / fAspect;
    
	CMatrix44 projMatrix;
	projMatrix.11 = fXScale;
	projMatrix.22 = fYScale;
	projMatrix.33 = fFarClip / ( fNearClip - fFarClip );
	projMatrix.34 = -1.0f;
	projMatrix.43 = fNearClip * fFarClip / ( fNearClip - fFarClip );
	return projMatrix;
}

CMatrix44 GetViewMatrix()
{
	SCameraInfo *pCamera = GetActiveCamera();
	Delegates::CGCamera__Forward_t pForward = reinterpret_cast<Delegates::CGCamera__Forward_t>
		( Process::GetVirtualMethod( (DWORD_PTR) pCamera, Offsets::VirtualMethods::Camera_Forward ) );

	CVector3 vCamLookAt;
	pForward( pCamera, &vCamLookAt );
	vCamLookAt += pCamera->Position;

	CMatrix44 viewMatrix;
	CVector3 vZAxis = CVector3( pCamera->Position - vCamLookAt ).normalize();
	CVector3 vXAxis = CVector3( 0, 0, 1 ).cross( vZAxis ).normalize();
	CVector3 vYAxis = vZAxis.cross( vXAxis );
	viewMatrix.11 = vXAxis.X; viewMatrix.12 = vYAxis.X; viewMatrix.13 = vZAxis.X;
	viewMatrix.21 = vXAxis.Y; viewMatrix.22 = vYAxis.Y; viewMatrix.23 = vZAxis.Y;
	viewMatrix.31 = vXAxis.Z; viewMatrix.32 = vYAxis.Z; viewMatrix.33 = vZAxis.Z;
	viewMatrix.41 = vXAxis.dot( pCamera->Position );
	viewMatrix.42 = vYAxis.dot( pCamera->Position );
	viewMatrix.43 = vZAxis.dot( pCamera->Position );
	viewMatrix.44 = 1.0f;
	return viewMatrix;
}

So as you can see only position is what I get from cam struct.
