moving sf::View from sf::RenderWindow

[Stauricus]

hello everybody
is there any way to directly move the view copy stored in the window object?

sf::RenderWindow window;
sf::View view;

view.setCenter(sf::Vector2f(100, 0));
view.setSize(400, 400);
window.create(sf::VideoMode(400,400), "Test!");
window.setView(view);
 

according to this topic, i should call this line every time the view is changed, but it made my cpu usage go from less than 1% to about 48%

window.setView(view);

so, isn't there any way to directly move the view copy stored in the window object?
thanks in advance!

No.

I really doubt that the setView() call is the cause for the higher CPU usage. You should measure with a profiler, not with the task manager or top. Otherwise, can you reproduce the issue in a minimal example?

you are absolutely right. the problem was moving the view in a big tiled world.
i changed the code a bit, so it now only renders around the view. altough the CPU usage goes up a little bit, it stays under 8%.

thanks for the tip on Profilers. i really was getting the information from lxtask
