Thanks for the reply :')
Can you explain me with an example?
such as,this one(can't upload photo from phone :/ )
keyboard>on F pressed>>player:set platform vector Y to player.Y-5
This is suppose to make my player fly.It works.But I don't understand it & don't know how to modify it.
Vector Y and Vector X are another method of describe a vector (the other one is with a angle and a strengh)
In fact, the larger the value of the Vector Y is, the quickier your player goes down or rise, the sign (+ or -) define if you will go Down or Up
EDIT: Also, don't forget the gravity can influence the vector Y after you set it
