Viewmatrix and WorldToScreen

[crvs899]

I am working on my first CSGO hack. Before i get into details, the hack is external and I am using C#. My problem is that when I read the view matrix and try and convert player positions to screen points, I get ridiculously weird numbers. Sometimes the numbers when converted to strings read out "NaN" which I know means undefined. Here is a table of what I'm talking about.

ViewMatrix:

1.79498E+21	-1.215803E-11	1.680519E-33	-1.122565E-06
3.888831E-20	-9735.812	3.186712E+38	-8.520999E+13
-3.5921E-14	-6.890327E+13	-2.064528E+26	-6.869414E+13
9.530977E+14	-1.121148E-06	-5.784123E+19	-1.118947E-06

Some of the bots positions + my position(I'll filter it out later) after converted to screen

102512.2	Infinity
61532.27	Infinity
43722.18	Infinity
38530.59	Infinity
79687.25	Infinity

I don't know if I am reading the view matrix wrong (I have tried multiple different ways) or if I am converting the points wrong.
Here is my code:

get Viewmatrix

public static float[] GetMatrixArray(ref ProcessMemory mem)
 {
     float[] flt = new float[16];
     Buffer.BlockCopy(mem.ReadMem(mem.Pointer("client.dll", Offsets.viewMatrix), 64), 0, flt, 0, mem.ReadMem(mem.Pointer("client.dll", Offsets.viewMatrix), 64).Length);
     //byte[] tempBytes = mem.ReadMem(mem.Pointer("client.dll", Offsets.viewMatrix), 64);
            
     //for(int i = 0; i < 16; i++)
     //{
     //    flt[i] = BitConverter.ToSingle(tempBytes, (i * 4));
     //}
     return flt;
 }

World to Screen Function (Version with floats) I have another version of this function which is the same code but the Viewmatrix is a struct

bool WorldToScreenFloat(ref V3 position, ref Vector2 screenPosition)
{
	float[] floatMatrix = MatrixUtils.GetMatrixArray(ref mem);
	float w = 0.0F;
	screenPosition.X = floatMatrix[0] * position.x + floatMatrix[1] * position.y + floatMatrix[2] * position.z + floatMatrix[3];
	screenPosition.Y = floatMatrix[4] * position.x + floatMatrix[5] * position.y + floatMatrix[6] * position.z + floatMatrix[7];
	w = floatMatrix[12] * position.x + floatMatrix[13] * position.y + floatMatrix[14] * position.z + floatMatrix[15];

	if (w < 0.1F)
		return false;

	float inv = 1.0F / w;
	screenPosition.X *= inv;
	screenPosition.Y *= inv;

	int width = Screen.PrimaryScreen.Bounds.Width;
	int height = Screen.PrimaryScreen.Bounds.Height;

	float x = width / 2;
	float y = height / 2;

	x += (float)(0.5F * screenPosition.X * width + 0.5F);
	y -= (float)(0.5F * screenPosition.Y * height + 0.5F);

	screenPosition.X = x + this.Left;
	screenPosition.Y = y + this.Top;

	return true;
}

I have also attached the image of the information from the tables outputted onto my overlay. Thank you for the help.
