|
|
// Description : Simple directed vector force. This force is
|
|
// different from the others in that it can be
|
|
// global and still only affect a single object.
|
|
// That might not make sense for a physics simulation,
|
|
// but it's very handy for a game. I.e. this is
|
|
// the force applied by user on the selected object.
