How to check for a mouse drag

how do you shoots on your script?

http://docs.unity3d.com/ScriptReference/$$anonymous$$onoBehaviour.On$$anonymous$$ouseDrag.html

Yeah what flapy says, it will be easy to help you once we see some code.

Thank you for the reference, martin.

I instantiate a bullet gameObject when the user clicks.

ok, here is some code that I use:

 public void Update()
         {
             if(isEquipped == true)
             {
                 if (Input.Get$$anonymous$$ouseButtonUp(0)&&isDragging == false) 
                 {
                     onItemClicked();
                 }
             }
         }
     
     public void on$$anonymous$$ouseDrag()
         {
             isDragging = true;
         }
     
     public void onItemClicked()
         {
             if(itemType == itemTypes.WeaponRanged&&isDragging == false)
             {
                 GameObject bullet = Instantiate(Resources.Load("Items/Weapons/Bullet")) as GameObject;     
                 bullet.GetComponent<Bullet>().gunBarrel = transform.FindChild("Cylinder").gameObject;
             }
         }
 

I am aware that there is nothing to disable isDragging, but the bullet still shoots regardless.

Edit: In the reference, it says:

On$$anonymous$$ouseDrag is called when the user has clicked on a GUIElement or Collider and is still holding down the mouse.

This will not work, as the user can drag anywhere to turn the camera
