class counterpart of mel function gravity
A gravity field simulates the Earth’s gravitational force. It pulls objects in a fixed direction (generally downward) entirely independent of their position or mass. The transform is the associated dependency node. Use connectDynamic to cause the field to affect a dynamic object. If fields are created, this command returns the names of each of the fields. If a field was queried, the results of the query are returned. If a field was edited, the field name is returned. If object names are provided or the active selection list is non-empty, the command creates a field for every object in the list and calls addDynamic to add it to the object. If the list is empty, the command defaults to -pos 0 0 0. Setting the -pos flag with objects named on the command line is an error. The default for -dx -dy -dz is always the opposite of the current up direction. For example, if the current up direction is (0,1,0) (a standard Maya configuration), then the gravity default is -dx 0 -dy -1 -dz 0. The default for -a is 9.8. 9.8 meters per second squared happens to be standard Earth gravity, but in fact Maya interprets this value as centimeters per second squared. If we were to use it as meters per second squared then with default Maya units, your particles would vanish almost in the wink of an eye. If you want a different value, set it in the gravity option box.
Returns the direction of the gravitational force.
