Hello! it seems like there's a bug on the lastest rev, if I do something like this:
MorphToFloatEntity(entity_, "rotation", _rotation, _interpolation_time,INTERPOLATE_LINEAR,2000);
where 2000 is the time that the interpolation should wait before starting, but it starts instantly and it ignores that parameter completly

Thank you!

never mind it was a bug caused by a mistake I made! it works !
