lerp method
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.
In general, however, it is possible for this to return null, especially
when t
=0.0 and begin is null, or t
=1.0 and end is null.
Implementation
@override
double lerp(double t) {
return super.lerp((math.sin((t - delay) * 2 * math.pi) + 1) / 2);
}
