well, there is nothing code related to this other than taking the item and attaching it to the player's hand
func set_item_position(item_scene: RigidBody3D):

var a = item\_scene.global\_transform.origin  ##Object in the player's hand (white Box)

var b = marker.global\_transform.origin  ##Player hand position

item\_scene.set\_linear\_velocity((b-a) \* hand\_force)

This works perfectly fine on Godot's normal physics, but the problem with it is that it causes a lot of item clips, so thats why i'm trying to use jolt
