Title: Set sprite origin.
Post by: Enok on November 20, 2014, 02:41:13 pm

Hello.

Setting the sprite origin doesn't seem to work.

I can't really see what I'm doing wrong here, everything else works just fine. I can't set the Origin even if I do it directly to the sprite itself, rather than using properties.

        public void LoadContent()
        {
            player.Origin = new Vector2f(player.Scale.Y, player.Scale.Y) / 2;
        }
 

        public Vector2f Origin { get { return this.sprite.Origin;  } set { this.sprite.Origin = value;  } }

And how do you verify that "it doesn't work"?

It doesn't do anything. It doesn't change the origin, nothing happens. There's no difference with or without it. No matter what numbers I type in, the sprites origin is always in the top-left.

Provide a complete and minimal example.

This is what it looks like when I just draw the sprite.

This is what it looks like with player.Origin = new Vector2f(50,50);

Game.cs

namespace PointAndClick
{
    class Game
    {

        Player player = new Player();



        public void LoadContent()
        {
            player.Texture = new Texture(Converter.ToSFTexture(Resources.spr_cannon_barrel));
            player.Origin = new Vector2f(50, 50);
        }

        //Physics, move stuff.
        public void FixedUpdate(TimeSpan deltaTime)
        {

        }

        //Draw stuff, check for input
        public void Update(RenderWindow rWindow)
        {
            rWindow.Clear(new Color(25,18,63));
            player.Draw(rWindow);
            rWindow.Display();
        }

        public static void UnloadContent()
        {

        }
    }
}
 

Player.cs

namespace PointAndClick
{
    public class Player
    {
        private Sprite sprite = new Sprite();

        //Transform
        public Vector2f Position { get { return this.sprite.Position; } set { this.sprite.Position = value; } }
        public Vector2f Scale    { get { return this.sprite.Scale;    } set { this.sprite.Scale = value;    } }
        public float Rotation    { get { return this.sprite.Rotation; } set { this.sprite.Rotation = value; } }

        public Texture Texture { get { return this.sprite.Texture; } set { this.sprite.Texture = value; } }
        public Vector2f Origin { get { return this.sprite.Origin;  } set { this.sprite.Origin = value;  } }
       
        public void Draw(RenderWindow rWindow)
        {
            rWindow.Draw(this.sprite);
        }
    }
}

^^ Works fine.

(click to show/hide)

public class Player
    {
        private Sprite sprite = new Sprite();

        //Transform
        public Vector2f Position { get { return this.sprite.Position; } set { this.sprite.Position = value; } }
        public Vector2f Scale { get { return this.sprite.Scale; } set { this.sprite.Scale = value; } }
        public float Rotation { get { return this.sprite.Rotation; } set { this.sprite.Rotation = value; } }

        public Texture Texture { get { return this.sprite.Texture; } set { this.sprite.Texture = value; } }
        public Vector2f Origin { get { return this.sprite.Origin; } set { this.sprite.Origin = value; } }

        public void Draw(RenderWindow rWindow)
        {
            rWindow.Draw(this.sprite);
        }
    }
    public static class Program
    {
        private static Player p = new Player();
        private static readonly Color CornflowerBlue = new Color(100, 149, 237);

        public static void Main(string[] args)
        {
            RenderWindow window = new RenderWindow(new VideoMode(1280, 720), "SFML Window");
            window.Closed += (sender, eventArgs) => window.Close();

            LoadContent();

            while (window.IsOpen())
            {
                window.DispatchEvents();

                window.Clear(CornflowerBlue);
                p.Draw(window);

                window.Display();
            }
        }
        public static void LoadContent()
        {
            p.Texture = new Texture("marsu.jpg");
            p.Origin = new Vector2f(-100, -100);
        }
    }
