How to fix sprite rotation problem?

Question

C++ / C#

Hello. Please, tell me the solution to the problem of rotating the sprite on the screen.. There is a similar code in two files:
.h file: https://github.com/Debug-/samp-omega/blob/master/C...
.cpp file: https ://github.com/Debug-/samp-omega/blob/master/C...
The bottom line is that when the rotation changes (here: https://github.com/Debug-/samp-omega/blob/ master/C... the rotation angle itself does not seem to change.I
think when changing, you need to recalculate the location of the sprite on the screen, so before the Draw function ( https://github.com/Debug-/samp-omega/blob/master/ C... added SetTransformation ( https://github.com/Debug-/samp-omega/blob/master/C... but to no avail(
What solution to the problem can be? Many thanks to whoever helps.

You have the matrix updated in the Sprite::SetTransformation method, but you don't apply it to your sprite. Most likely it should be done.

void Sprite::SetTransformation()
{
    D3DXVECTOR2 spriteCenter = center;
    D3DXVECTOR2 trans = pos;
    D3DXVECTOR2 scaling = scale;
    D3DXMatrixTransformation2D(&mat, NULL, 0.0, &scaling, &spriteCenter, rotation, &trans);
    sprite->SetTransform(&mat);
}
