How to make the vertical axis relative.

Question

I have a pick up and hold items script and the object I'm carrying is moved on the horizontal axis but stays on the same level on the vertical axis. How do I fix this? The object is teleported to a hand empty which doesn't move on the axis.

This is how I hold it correctly: alt text

And this is how I hold it when I look down: alt text

I'd like to be able to hold it in like the first picture when looking up and down.

This is my script:

 using UnityEngine;
 using System.Collections;
 
 #pragma warning disable 0414
 
 namespace CarryingItems {
 
     public class PickUp : MonoBehaviour {
         
         private float RayCastLength = 2.15F;
         public LayerMask RayMask;
         
         private float OffsetDropPosition = 2;
         
         private GameObject UtilityProps;
         private GameObject CarryableObject;
         private GameObject Hand;
         private GameObject Character;
         private GameObject CameraMain;
         private GameObject Handle;
         private GameObject HandleExtra;
         private GameObject BladeHolder;
         private GameObject Blade;
         
         private bool ItemPickedUp;
         
         void Awake() {
             UtilityProps = GameObject.Find("UtilityProps");
             CarryableObject = this.gameObject;
             Hand = GameObject.Find("ItemHand");
             Character = GameObject.Find("PlayerCharacter");
             CameraMain = GameObject.Find("MainCamera");
             Handle = this.gameObject.transform.GetChild(0).gameObject;
             HandleExtra = this.gameObject.transform.GetChild(1).gameObject;
             BladeHolder = this.gameObject.transform.GetChild(2).gameObject;
             Blade = this.gameObject.transform.GetChild(3).gameObject;
         }        
         
         void Start() {
             ItemPickedUp = false;
         }
         
         void Update() {
             if (Input.GetKeyDown("e")) {    
                 if(ItemPickedUp == false) {
                     ItemPickUp();
                 }
                 else if(ItemPickedUp == true){
                     ItemDrop();
                 }
             }            
         }
         
         void ItemPickUp() {
             if (Physics.Raycast(CameraMain.transform.position, CameraMain.transform.forward, RayCastLength, RayMask.value)) {
                 CarryableObject = this.gameObject;
                 CarryableObject.transform.parent = Character.transform;
                 CarryableObject.GetComponent<Rigidbody>().useGravity = false;
                 CarryableObject.GetComponent<Rigidbody>().isKinematic = true;
                 CarryableObject.transform.position = Hand.transform.position;
                 CarryableObject.transform.rotation = Hand.transform.rotation;
                 ItemPickedUp = true;
                 
                 if(Handle != null){
                     Handle.GetComponent<Collider>().enabled = false;
                 }
                 if(HandleExtra != null){
                     HandleExtra.GetComponent<Collider>().enabled = false;
                 }
                 if(BladeHolder != null){
                     BladeHolder.GetComponent<Collider>().enabled = false;
                 }
                 if(Blade != null){
                     Blade.GetComponent<Collider>().enabled = false;
                 }
             }
         }
         
         void ItemDrop() {
             CarryableObject.transform.parent = null;
             CarryableObject.transform.position = CameraMain.transform.position + CameraMain.transform.forward*OffsetDropPosition;
             CarryableObject.transform.rotation = Character.transform.rotation;
             CarryableObject.GetComponent<Rigidbody>().useGravity = true;
             CarryableObject.GetComponent<Rigidbody>().isKinematic = false;
             ItemPickedUp = false;
             
             if(Handle != null){
                 Handle.GetComponent<Collider>().enabled = true;
             }
             if(HandleExtra != null){
                 HandleExtra.GetComponent<Collider>().enabled = true;
             }
             if(BladeHolder != null){
                 BladeHolder.GetComponent<Collider>().enabled = true;
             }
             if(Blade != null){
                 Blade.GetComponent<Collider>().enabled = true;
             }
         }    
     }
 }

PS: Bonus points if you can help me with the fact that I grab 2 items when i try to pick up the cleaver.

What does your hierarchy and pickup script look like? The easiest way would be to have an empty parented to your camera or whatever moves your character and then have the item you're carrying parented to that empty. Then just keep the item's position at 0,0,0 so it follows the empty.

I have a hand empty where the item spawns to but it doesn't rotate.

I updated my question because I didn't have enough characters to put the script in the comment.

This is my hierarcy: alt text

And I tried to make my hand position relative to the camera but the object turned sideways and I wasn't able to turn it.

Your ItemHand GameObject follows your Character GameObject correctly? If so try this:

Ins$$anonymous$$d of

 CarryableObject.transform.parent = Character.transform;

try

 CarryableObject.transform.parent = Hand.transform;

And ins$$anonymous$$d of

 CarryableObject.transform.position = Hand.transform.position;

try

 CarryableObject.transform.position = Vector3.zero;

This should make your item always follow the hand, no matter where it goes. Of course, all this will only work if your hand moves in the right place on the camera. You might have to play around with the CarryableObject's rotation to get things looking right, but it should stick in place now at least.

As for the double cleaver, I'm not sure. It would take some more investigation to figure out I think

The problem is that the hand empty is being moved on the vertical axis. Not just the object. But thank you for your advise. $$anonymous$$y question wasn't very clear about that. Apologies!
