Throwing a ball against other object

Hi all!

I'm really a noob on Ogre. I have to do an exercise to college, but I really don't know how to do it...

The Ogre application that I have to do is:
--> Press space bar and throw a ball against a wall made of cubes. The origin of the throwing is the cammera.

I did the wall, but I don't have any idea how I should code the ball being throwing.

I'd appreciate any help.

Are you using OgreOde then? Or wrapping Ode yourself? And, more importantly, are you using Ode at all?

Yeah, I'm using OgreODE.

well, then on your "spaceBar_pressed" event you have:
create new body;
create new sphere geometry;
assign geometry to the body;
set body's position at the camera position;
set body's linear force to something in the camera's direction;
enjoy!

To get more code specific, visit the wiki or look at the demos.
