Question

hi i have to rotate a Texture2D, but i dont know why.
its like a have a picture and i need to rotate it 180° because it’s on the head and should be right.

the problem is, i need to do it before i use spriteBatch.Draw, is this possible?

Answer 1

The texture will be rotated by 180 degree.

    protected override void Draw(GameTime gameTime)
    {
        spriteBatch.Begin(SpriteSortMode.Deferred, BlendState.AlphaBlend, SamplerState.LinearWrap, DepthStencilState.None, RasterizerState.CullCounterClockwise, null);
        spriteBatch.Draw(texture, Position, null, Color.White, (float)Math.PI, new Vector2(texture.Width, texture.Height), 1, SpriteEffects.None, 0);
        spriteBatch.End();
        base.Draw(gameTime);
    }

As also you can flip texture vertically using SpriteEffects:

    protected override void Draw(GameTime gameTime)
    {
        GraphicsDevice.Clear(Color.CornflowerBlue);
        spriteBatch.Begin(SpriteSortMode.Deferred, BlendState.AlphaBlend, SamplerState.LinearWrap, DepthStencilState.None, RasterizerState.CullCounterClockwise, null);
        spriteBatch.Draw(texture, Position, null, Color.White, 0, Vector2.Zero, 1, SpriteEffects.FlipVertically, 0);
        spriteBatch.End();
        base.Draw(gameTime);
    }
