Question by Trashboat95 · Aug 16, 2017 at 07:30 PM · rigidbodytransform.positionfirst person shootermagnetthrowing

Help with pulling objects toward player

Hey all!

In my FPS game, the player's main attack is throwing knives. Pretty straightforward. However, I want to add an ability to "recall" the knives (with a key press) once they're thrown into an enemy, dealing damage and returning back to the player to be added for future throws. I want the core mechanics to work before I implement damage, ammo, etc. It works to some extent but...

The problem I am facing is that when I recall the knives, they only go to the initial spawning point of the first person character. I can't seem to get them to return to the player's current position. I thought maybe making the transform.position = a new Vector3, but I cant lerp a new Vector... Even assigning the RigidBodyFPSController to the target of my script in the inspector doesn't change how it acts. I have looked into magnet scripts, I have googled around but i can't find a straightforward answer to my problem. Thanks in advance guys, I'm just a coding noob, but I'm getting there!

This is the code that is attached to the throwing knives.

 using UnityEngine;
 using System.Collections;
 
 public class KnifeBrain : MonoBehaviour {
 
     public float speed;
     public Transform target;
 
     // Use this for initialization
     void Start() {
         
     }
 
     // Update is called once per frame
     void Update() {
         transform.Rotate(0, 0, speed);
 
         if (Input.GetKey(KeyCode.E)) {
             Rend();
         }
     }
 
     void OnCollisionEnter() {
         GetComponent<Rigidbody>().isKinematic = true;
         speed = 0;
     }
 
      void Rend () {
         GetComponent<Rigidbody>().isKinematic = false;
         speed = 10;
 
         transform.Rotate(0, speed, 0);
 
         float step = speed * Time.deltaTime;
 
         transform.position = Vector3.Lerp(transform.position, target.position, step); 
     } 
 } 

How can I tweak Rend () so that they always come back to the player's position?
