copy method
Copies property values, currently doesn't trigger change callbacks. It's meant to be a helper for clone.
Implementation
@override
void copy(Core source) {
super.copy(source);
if (source is LinearAnimationBase) {
_fps = source._fps;
_duration = source._duration;
_speed = source._speed;
_loopValue = source._loopValue;
_workStart = source._workStart;
_workEnd = source._workEnd;
_enableWorkArea = source._enableWorkArea;
_quantize = source._quantize;
}
}
