No, negative height won't work. That is GDI specific thing in Windows.
What you want is to set transform matrix for draw calls. If I'm not mistaken. SpriteBatch.Begin method has an overload that allows to pass transform matrix in argument. So create a matrix that does vertical flip (scale with -1) and it should draw everything vertically flipped.

But i'm currently using a 2D camera
So ,if I change this,
to this
It still doesn't work.
And the matrix is passed to SpriteBatch.Begin method as you said.
So ,if I change this,
1 2 3 4 5 6 7 8 9 | public Matrix get_transformation()
{
_transform =
Matrix.CreateTranslation(new Vector3(-_pos.X, -_pos.Y, 0)) *
Matrix.CreateRotationZ(Rotation) *
Matrix.CreateScale(Zoom,Zoom,Zoom)*
Matrix.CreateTranslation(new Vector3(graphicsDevice.Viewport.Width * 0.5f, graphicsDevice.Viewport.Height * 0.5f, 0));
return _transform;
}
|
to this
1 2 3 4 5 6 7 8 9 | public Matrix get_transformation()
{
_transform =
Matrix.CreateTranslation(new Vector3(-_pos.X, -_pos.Y, 0)) *
Matrix.CreateRotationZ(Rotation) *
Matrix.CreateScale(Zoom,-Zoom,Zoom)*
Matrix.CreateTranslation(new Vector3(graphicsDevice.Viewport.Width * 0.5f, graphicsDevice.Viewport.Height * 0.5f, 0));
return _transform;
}

After some tuning and thinking and drawing diagrams here's a fixed. But if there's another method please share. Anyways here's my Solution,
This is passed to Spritebatch.begin -- Matrix param
This is passed to Spritebatch.Draw -- Vector2 position param
This is passed to Spritebatch.begin -- Matrix param
1 2 3 4 5 6 7 8 9 | public Matrix get_transformation()
{
_transform =
Matrix.CreateTranslation(new Vector3(-_pos.X, _pos.Y, 0)) *
Matrix.CreateRotationZ(Rotation) *
Matrix.CreateScale(Zoom,Zoom,1.0f)*
Matrix.CreateTranslation(new Vector3(graphicsDevice.Viewport.Width * 0.5f, graphicsDevice.Viewport.Height * 0.5f, 0));
return _transform;
}

This is passed to Spritebatch.Draw -- Vector2 position param
1 2 3 4 5 6 | public Vector2 WorldtoScreen(Vector2 In)
{
Vector2 Result = In;
Result.Y = -In.Y;
return Result;
}
