When using sf::View, the content displayed in the window will change as the perspective moves,How to keep a graphic in a specific position in the window at all times
My current approach is to follow the perspective and change the position of the content, so as to always maintain a specific position in the window. Is there a better way?For example, simply skip the view and draw on the window

If you want for example an UI element always shown at the same location, it's better and easier to just use a separate view for those elements.

As a simple example to what eXpl0it3r mentioned:
sf::View mainView; // the view you are using now. you can move this however you like
sf::View windowView; // this one matches the window
windowView = window.getDefaultView(); // this is how you can match the view to the window (but it will need updating if the window changes)
// ..
window.setView(mainView); // your normal view
window.draw(yourStuff); // the stuff that moves "perspective"
window.setView(windowView); // static window view
window.draw(ui); // the stuff you want to draw relative to the window, ignoring the other view such as a user interface

Remember, though, that - depending on how you use it - you may need to set the window to a specific view before doing certain updates. This is if you use the "current window's view" for any calculations; you can, of course, remove this requirement and use the correct view directly.
