Title: Is it possible to draw FloatRects to the screen?
Post by: dotty on January 22, 2012, 07:34:31 pm

As the title suggests, I'm using FloatRects for some collision detection. Is it possible to draw these to the screen so I can see their positions? I know I could simple copy the attributes of said FlaotRect then create a Shape, but I'm wondering if it's possible without the need of using Shape.

Thanks!

If you are using SFML 2 you can use sf::Vertex class. If not, I think that sf::Shape is the unique option (unless you use openGl directly).

Omg, I have not noticed about that class until now :lol:
Sorry, anyway it's a sf::Shape based class.

but RectangleShape doesn't have the methods like Intersect and Contains though.

Just use your FloatRect for collision detection and create a RectangleShape from it when drawing:

Code: [Select]

sf::RectangleShape shape(sf::Vector2f(rect.Width, rect.Height));
shape.SetPosition(rect.Left, rect.Top);
window.Draw(shape);

I guess that's the only way to do it. Ok, thanks.
