Hello everyone,
I am sorry for disturbation!
I really don’t understand why does my rect make half than it happens like crazy. How do I fix if I want make
But for me only vertices…
// EDIT:
My result:
This is Maths.cs
using Microsoft.Xna.Framework;
namespace MyTransformation
{
public class Maths
{
public static Matrix CreateTransformationMatrix(Vector3 position, float rotX, float rotY, float rotZ, float rescale)
{
Matrix translation = Matrix.CreateTranslation(position);
Matrix rotationX = Matrix.CreateRotationX(rotX);
Matrix rotationY = Matrix.CreateRotationY(rotY);
Matrix rotationZ = Matrix.CreateRotationZ(rotZ);
Matrix scale = Matrix.CreateScale(rescale);
Matrix transformation = translation * rotationX * rotationY * rotationZ * scale;
return transformation;
}
}
}
This is Entity.cs
using Microsoft.Xna.Framework;

this.game = game;

this.rotY = rotY;
this.rotZ = rotZ;
this.scale = scale;
}

{
position.X += distanceX;
position.Y += distanceY;
position.Z += distanceZ;
}

result: it looks like crazy
Do you remember that original texture is 8 x 8 tiles black / white
like this
Since my monogame with transformation looks like 4 x 8 like it is wrong. and it happens “replying mode” why does matrix not work like limited matrix?
How do I fix if I have already made normal texture length of width and height ( just same in vertices ) But it happens half of rectangle. Why does it happen? What is it wrong?
Edit I have fixed add transformationMat in Shader.fx than it won’t move translate only rotate???
Why does it not work if I use add float4x4 transformationMat
in VS-Function
float4x4 together = worldviewprojection * transformationMat;
Is it correct or wrong?`What do I fix? I need add more for shader or do not need shader?
I try with
float4x4 worldviewprojection =
{
{ 1, 0, 0, 0},
{ 0, 1, 0, 0},
{ 0, 0, 1, 0},
{ 0, 0, 0, 1}
}
And it looks maniac 
WHY IS RECTANGLE HALF???
Thank you for help and I appreciate that.
I am very excited next serie creating cube wow.
