Problem using delta time
« on: April 15, 2021, 12:13:09 pm »
I am trying to make an int function that returns delta time and it doesn't work. Any idea what can I do?
float deltaTime() {
    sf::Clock deltaClock;
        sf::Time dt = deltaClock.restart();
        std::cout << dt.asSeconds() << std::endl;
        return dt.asSeconds();

Please read this thread first.
This concerns a lot of your posts here.

And please spend at least 10 seconds formulating a clear question without typos, if you expect people to spend several minutes answering.

Your deltaTime() function is making a new clock every time you call it. The clock starts at zero.
You need to make one clock and keep using it. Either move the clock outside of the function or place the "static" keyword before the clock in the function. (Static on a variable in a function makes it continue to live after the function ends and reuses it next time without recreating it).
