    Making the sprite's image turn by an angle

    Reply Quote
    I'm making a version of the game Tank and I am using the mouse to set the angle of my turret.  The problem is that I don't know how to make the turret turn to the angle so it looks in the right direction.  How do I make the turret spin? Do I have to make many pictures of the turrets multiple positions?

    No, just use SpriteBatch.Draw() with a rotation != 0.

    Use one of these 3 overloads:

            public void Draw(Texture2D texture, Rectangle destinationRectangle, Rectangle? sourceRectangle, Color color, float rotation, Vector2 origin, SpriteEffects effects, float layerDepth); 
            public void Draw(Texture2D texture, Vector2 position, Rectangle? sourceRectangle, Color color, float rotation, Vector2 origin, float scale, SpriteEffects effects, float layerDepth); 
            public void Draw(Texture2D texture, Vector2 position, Rectangle? sourceRectangle, Color color, float rotation, Vector2 origin, Vector2 scale, SpriteEffects effects, float layerDepth);

    Type SpriteBatch.Draw() and cursor over the Draw, and press F1 or F12.  The best way to learn is to look up the details from MSDN yourself.  It's a good habit to get used to.
