Title: [SOLVED] How to move the View?
Post by: MickeyKnox on June 19, 2020, 07:50:27 pm

window.getView().move(0, 1);

doesn't work, because Window::getView is const, while View::move isn't.

How am I supposed to move the View?

Get your sf::View as a variable, move it, and set it with setView

What do you mean by "Get your sf::View as a variable"?

The View from Window via getView()? Or do you mean a fresh View? How would I initialize that?

Everytime I move the View I have to set it with setView? Or can I move the view as much as I want once I've set it?


Edit:
I've tried setting a new View, but the Image is distorted.

I think that the default View in Window somehow gets initialized to my Desktop resolution (I'm running in fullscreen), but a new View gets some default resolution, resulting in a distorted Image. Initializing the View with the viewport from the view from window also didn't help.

sf::View view = window.getView();
view.move(0, 1);
window.setView(view);

Yes, you have to set the view when you modify it.

You don't need to modify the viewport to just move the view.
