Title: Spike lag
Post by: PewPew on August 06, 2016, 07:28:08 am

I keep having this spike lag on my pong game

here is the code

while (window.isOpen())
        {
                window.setFramerateLimit(60);
                sf::Event event;
                dt = deltatime.getElapsedTime().asSeconds();
               
                update(event,dt);
                while (window.pollEvent(event))
                {
                        if (event.type == sf::Event::Closed || sf::Keyboard::isKeyPressed(sf::Keyboard::Escape))
                                window.close();
                }
                if (mClock.getElapsedTime().asSeconds() >= 1.f)
                {
                        mFps = mFrame;
                        mFrame = 0;
                        mClock.restart();
                       
                }

                ++mFrame;
                //std::cout << mFps << std::endl;

                this->deltatime.restart();
                window.clear(color);
                player->Render(window);
                ball->Render(window);
                window.display();
       

        }

IM guessing its the deltatime. But I dont see the connection. My computer is a medium gaming rig so I shouldnt have this lag spike.

Every time I move the paddle theres this spike lag happening. Same as the ball. Might be my computer but it doesnt seem to be like that on monogame.

Maybe you should define "spike lag"...

You made up the term, now explain to us what it means. What exactly is a "spike lag"?

start by moving
window.setFramerateLimit(60);
outside the loop
