Box2D world size
I have created a box2d world, and I wanted to limit the height of the world. 
I did search google and apparently there was an option in the previous version of box2d where you would have to define the size of your world, but I am not sure if you were able set the height of the world but in the current version they have taken that option completely off. 

So I am just looking for a way to limit the height, as my player is a ball that jumps up and down and I want to limit how high it can jump (the jumps are done by physics and gravity and the speed of the ball so after a few good jumps, the ball jumps really high as its speed increases and I dont want to limit the speed) and put border on let say `y=900`.
