How to make dominoes topple?

Questions & Answers

We are trying to setup a scene where dominoes topple but are not able to initiate the chain. We tried add.torque but it doesn’t seem to work, maybe there’s some problem with the script. We also tried transform.rotate which works fine but after falling keeps on vibrating on the plane.

Try adding this script to the first domino, correcting it for the strength and desired axis of rotating along which you would like the torque to be applied:

using UnityEngine;
using System.Collections;

public class AddTorque : MonoBehaviour {

	// This determines the strength and direction around the selected axes in which the torque is applied 
	float torqueStrength = -25.0f;

	// Use this for initialization
	void Start () {
		// Modify this code for the Vector3 to be the axis you want to torque to be applied around (local to the domino)
		rigidbody.AddRelativeTorque( Vector3.right * torqueStrength );
	}
	
	// Update is called once per frame
	void Update () {
	
	}
}

Typically you push the first one over and let physics do the rest. RigidBody.AddForce would be the unity equivalent.
