I am having a difficult time trying to understand the Flappy Bird physics. I know it seems simple but I kind of suck at math. I am trying to see if I can make a simple game like this but it is just the dang physics that are throwing me off. I have something like gravity effecting the bird but when you click the screen and I add some amount to the y position but it doesn't look good. You guys have any ideas?
velocity += -9.8 * Gdx.graphics.getDeltaTime(); position.y += 0.5 * velocity;
That is falling but when I tap the device I would like to know how to add upward force but when it loses it continue falling.
