Anyone know how I could use this code (or code like this) to pick up a physics entity with the mouse? I've been having difficulty with this (I even started a thread that never got answered ), and this is an integral part of my biggest project right now.

Please answer this

Code:
void main()
{
    cout << "I am MrCode,";
    cout << "hear me roar!";
    system("PAUSE");
}
