lerp method

  1. @protected
T lerp (double t)
@protected

Returns the value this variable has at the given animation clock value.

The default implementation of this method uses the +, -, and * operators on T. The begin and end properties must therefore be non-null by the time this method is called.

Implementation 

@protected
T lerp(double t) {
  assert(begin != null);
  assert(end != null);
  return begin + (end - begin) * t;
}
