c# - How can I make this object relative to the players position? -

the player in game can levitate objects , move them around on world xy mouse. how can make levitating object move player when moves?

private void levitateobject() { //debug.log("levitating");  float yaxis = input.getaxis("mouse y"); float xaxis = input.getaxis("mouse x");  vector3 frontforce = playercamera.transform.transformdirection(vector3.forward) * (yaxis * 1.5f) ; vector3 rightforce = playercamera.transform.transformdirection(vector3.right) * (xaxis * 1.5f);  vector3 currpos = levitatingobject.transform.position; vector3 nextpos = new vector3 ( levitatingobject.transform.position, elevation,  levitatingobject.transform.position) + rightforce + frontforce;  levitatingobject.getcomponent < rigidbody > ().velocity = (nextpos - currpos) * 10; } 

i want below, object doesnt move @ all.

vector3 nextpos = new vector3 ( transform.position.x + (levitatingobject.transform.position.x -transform.position.x) , elevation, transform.position.z + (levitatingobject.transform.position.z -transform.position.z)); 

make player parent of object.

obj.transform.parent = player.gameobject; 

then object's position relative player's positio. when player moves, object.
