Object Interaction Script

Unity Engine
1

Could someone help me edit this java script please? It allows the player to lift objects with clicking the left mouse button to interact however you can do it from any distance. Would anyone edit to make you required to be a certain distance from the object you click?

I didn’t write the script

var spring = 50.0;
var damper = 5.0;
var drag = 10.0;
var angularDrag = 5.0;
var distance = 0.2;
var attachToCenterOfMass = false;

private var springJoint : SpringJoint;

function Update ()
{
	// Make sure the user pressed the mouse down
	if (!Input.GetMouseButtonDown (0))
		return;

	var mainCamera = FindCamera();
		
	// We need to actually hit an object
	var hit : RaycastHit;
	if (!Physics.Raycast(mainCamera.ScreenPointToRay(Input.mousePosition),  hit, 100))
		return;
	// We need to hit a rigidbody that is not kinematic
	if (!hit.rigidbody || hit.rigidbody.isKinematic)
		return;
	
	if (!springJoint)
	{
		var go = new GameObject("Rigidbody dragger");
		var body : Rigidbody = go.AddComponent ("Rigidbody") as Rigidbody;
		springJoint = go.AddComponent ("SpringJoint");
		body.isKinematic = true;
	}
	
	springJoint.transform.position = hit.point;
	if (attachToCenterOfMass)
	{
		var anchor = transform.TransformDirection(hit.rigidbody.centerOfMass) + hit.rigidbody.transform.position;
		anchor = springJoint.transform.InverseTransformPoint(anchor);
		springJoint.anchor = anchor;
	}
	else
	{
		springJoint.anchor = Vector3.zero;
	}
	
	springJoint.spring = spring;
	springJoint.damper = damper;
	springJoint.maxDistance = distance;
	springJoint.connectedBody = hit.rigidbody;
	
	StartCoroutine ("DragObject", hit.distance);
}

function DragObject (distance : float)
{
	var oldDrag = springJoint.connectedBody.drag;
	var oldAngularDrag = springJoint.connectedBody.angularDrag;
	springJoint.connectedBody.drag = drag;
	springJoint.connectedBody.angularDrag = angularDrag;
	var mainCamera = FindCamera();
	while (Input.GetMouseButton (0))
	{
		var ray = mainCamera.ScreenPointToRay (Input.mousePosition);
		springJoint.transform.position = ray.GetPoint(distance);
		yield;
	}
	if (springJoint.connectedBody)
	{
		springJoint.connectedBody.drag = oldDrag;
		springJoint.connectedBody.angularDrag = oldAngularDrag;
		springJoint.connectedBody = null;
	}
}

function FindCamera ()
{
	if (camera)
		return camera;
	else
		return Camera.main;
}

hi,

I made something similar like this:

	// We need to hit a rigidbody that is not kinematic
	if (!hit.rigidbody || hit.rigidbody.isKinematic)
		return;
		
	// check distance
	if (Vector3.Distance(myplayer.position, hit.transform.position)<dragRange) return;

I had 3rd person view so “myplayer.position” was player position (transform variable)
and “dragRange” is float or int variable (max range).

hit.transform.position is the contact position for drag.

Is there a way to implement the “Check Distance” into the script I posted above?

try with this sample scene.
