Grab'n Throw system

Questions & Answers

Well I haven’t posted in a while but here goes:

I am making a simple game where you can grab and throw things, but I don’t know any suitable script for making my grab’n throw system, I want the player to grab anything with a RigidBody and it’s tag has "holdable". It grabs anything that is on the mouse position when E is pressed, any code?

It feels pretty straight forward to me:

  1. attach a FixedJoint to your player and put a script that casts a ray from the mouse position to the world
  2. then just get the RigidBody of the object that the ray has hit
  3. and finally replace FixedJoint.connectedBody with that RigidBody.

I will probably update this answer with the code a bit later.

UPD: Something like this:

using UnityEngine;
using UnityEngine.Serialization;

public class ItemPicker : MonoBehaviour
{
    private FixedJoint joint;
    [SerializeField] private Camera cam;
    [SerializeField] private float reach;  //max distance at which an item would be picked

    private void Start()
    {
        joint = gameObject.GetComponent<FixedJoint>();
        cam = GameObject.FindGameObjectWithTag("MainCamera").GetComponent<Camera>();
    }

    private void FixedUpdate()
    {
        if (Input.GetKey(KeyCode.E))
        {
            if (joint.connectedBody is null)
            {
                RaycastHit hit;
                if (Physics.Raycast(cam.ScreenPointToRay(Input.mousePosition), out hit, reach))
                {
                    joint.connectedBody = hit.rigidbody;
                }
            }
            else
            {
                joint.connectedBody = null;
            }
        }
    }
}
