Not sure if I understand. Did you try to mess with the settings I provided you before?
The platform and event will only synchronize their positions when the event is a "CarryPlatform". Otherwise, they are both free to move. The purpose of the carrier platform is to take the player from one place to another, so the player is not supposed to move.
On the Normal Platform, the player needs to control his position, otherwise, the platform will move, and the player will fall.
So, on my understanding, you want a Carry Platform that lets the player change its direction while above it and also jump? Is that it?
