Description

OnMouseDrag is called when the user has clicked on a GUIElement or Collider and is still holding down the mouse.

OnMouseDrag is called every frame while the mouse is down.

// Darken the material color while user holds down the mouse.
var rend: Renderer;

function Start() { rend = GetComponent.<Renderer>(); }

function OnMouseDrag () { rend.material.color -= Color.white * Time.deltaTime; }
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { public Renderer rend; void Start() { rend = GetComponent<Renderer>(); } void OnMouseDrag() { rend.material.color -= Color.white * Time.deltaTime; } }

This function is not called on objects that belong to Ignore Raycast layer.

OnMouseDrag can be a co-routine, simply use the yield statement in the function. This event is sent to all scripts attached to the Collider or GUIElement.
