How can i propper rezise my Background Image

[CodingDolphin]

Good Morning Guy's,

i have a Problem i try to set my Background Image exactly too my Window Resolultion.

My Image Size is 1920,1080:

If i run the Game with a Desktop Resolution 1920,1080 everything is perfectly centered.

If i run now the Game with a Desktop Resolution 1600,900 the Image is always off and not centered i did try Transform, Scale everything i dont get centered im sure i do something wrong but it would be nice if you could give me a hint. (BTW. I use SFML.NET)

Set both the sprite origin and position to the center of your view.

Thanks for quick reply. i will try. But i seems im not able to Transform my Sprite, not sure what im doing wrong but my Sprite not Change after transform as you see in my Debug Step.

You're not supposed to modify the Transform property of the sprite (there's no way to programmatically disallow it in C#...). Please read the documentation and tutorials.
