Why does ball bounce higher off the ground?

Zizanyman

I am using box2d to make a flappy bird clone. When you tap the screen, the ball goes up. However, for some reason, it launches higher when you launch it from off the ground than it does when you click in midair. Here are the physics settings of the ball:

shape = circle, density = 1.0,
friction = 0.1, restitution = 0

And of the wall:

shape = poly, density = 1.0,
friction = 0.1, restitution = 0

Does anybody know why this is happening?

Hello, First of all sorry for my Inglés.

Have verified Friend That When You tap on the screen ... (I suppose you added onMouseDow Listener) These applying force more than once, try to have a Variable That controls the state Until the end of the impulse That These standing.
