Question by justking14 · Oct 29, 2014 at 01:49 AM · childlocalposition

added child location

So my code is supposed to pick up (add child to player controller) a nearby animal when the H key is pressed. Unfortunately, if the player is behind the animal he's trying to pick up, the animal is placed behind the player and out of sight. Any advice for fixing this?

  void Update () {
     GameObject[] agent;
     if(Input.GetKeyDown(KeyCode.H)){//if h was pressed
         agent = GameObject.FindGameObjectsWithTag("Finish");
         foreach(GameObject ag in agent){//find all animals with the tag of finish
             if(holding == false){//only pick up one
                 if((ag.rigidbody.position-rigidbody.position).magnitude<15){//find closest animal to player and pick it up
                     Held = ag;
                      if(Held.transform.position.z > transform.position.z){
                         Held.transform.parent = transform;
                     }else{
                         Debug.Log("TEST");
                         Held.transform.parent = transform;
                     }
                     holding = true;
                 }
             }
         }
     }
     if(holding == true){//if one is being held, reset position
         if(hold2 == false){
             hold2 = true;
             Held.transform.position =  new Vector3(-10f,0,0); 
         }
         Held.transform.localPosition = Vector3.zero;

     }
     if(Input.GetKeyUp(KeyCode.H) && holding == true){//if something is being held, upon release detach the player from the animal
         holding = false;
         Held.transform.parent = null;
         Held.rigidbody.velocity = Vector3.zero;
     }         
 }

Several ways you can do this. First is simply setting the held object's location to be in front of the player.

 //places the held object 2 units in front of player
 held.transform.position = player.transform.position + (player.transform.forward * 2);
 //or
 held.transform.localPosition = Vector3.forward * 2;


Another is to have an empty gameObject as a child of your player and placed in front of it. Setting all held objects to be a child of that empty GO then resetting its local transforms would place it exactly where the GO is.

hierarchy: player -> hand -> heldObject (to parent)

 held.transform.parent = hand.transform;
 held.transform.localPosition = Vector3.zero;

WOW. I really should've seen that second options. Thanks.
