Drag Rigidbody

[InfamousStudios]

I consulted search engine after search engine, forum after forum. I just can’t find a suitable answer to this question!

Is there a script that I can use, which allows the player to drag a rigidbody when it is clicked and dragged? I need this for a game, which you need to drag objects to create a bridge, allowing gravity to rotate it naturally. I don’t need to rotate it, just be able to drag it. Thanks in advance!

This was answered here:

If DragRigidBody doesn’t work for what you need, try using Erich5h5’s DragObject script:

I’m actually going to attempt this myself now.

Here, i wrote a very simple script for dragging any Object with the rigidbody component.
I hope i could help you.

using UnityEngine;
using System.Collections;

public class DragRigidbody : MonoBehaviour
{

public float catchingDistance = 3f;

bool isDragging = false;
GameObject draggingObject;

// Use this for initialization
void Start()
{

}

// Update is called once per frame
void Update()
{

    if (Input.GetMouseButton(0))
    {
        if (!isDragging)
        {
            draggingObject = GetObjectFromMouseRaycast();
            if (draggingObject)
            {
                draggingObject.GetComponent<Rigidbody>().isKinematic = true;
                isDragging = true;
            }
        }
        else if (draggingObject != null)
        {
            draggingObject.GetComponent<Rigidbody>().MovePosition(CalculateMouse3DVector());
        }
    }
    else {
        if (draggingObject != null)
        {
            draggingObject.GetComponent<Rigidbody>().isKinematic = false;
        }
        isDragging = false;
    }
}

private GameObject GetObjectFromMouseRaycast()
{
    GameObject gmObj = null;
    RaycastHit hitInfo = new RaycastHit();
    bool hit = Physics.Raycast(Camera.main.ScreenPointToRay(Input.mousePosition), out hitInfo);
    if (hit)
    {
        if (hitInfo.collider.gameObject.GetComponent<Rigidbody>() &&
            Vector3.Distance(hitInfo.collider.gameObject.transform.position,
            transform.position) <= catchingDistance)
        {
            gmObj = hitInfo.collider.gameObject;
        }
    }
    return gmObj;
}

private Vector3 CalculateMouse3DVector()
{
    Vector3 v3 = Input.mousePosition;
    v3.z = catchingDistance;
    v3 = Camera.main.ScreenToWorldPoint(v3);
    Debug.Log(v3); //Current Position of mouse in world space
    return v3;
}
