Please write here steps how to:
Attatch that weapon to FPS contoller and when I press mouse button it will play that animation.
help me Iam stuck.You know that feeling :frowning:

Without sounding callous I suggest you work through the FPS tutorial:

http://unity3d.com/support/resources/tutorials/fpstutorial

Doing so will enlighten you on a lot of the aspects of developing a game and save you a lot of headaches later on.

I watched fps tutorial.but there is no weapon animation when shooting.A gun just stay in the same place even you shooting.

http://unity3d.com/support/documentation/Manual/Character-Animation.html

From in that page there is:

function Update ()
{
   if (Input.GetAxis("Vertical") > 0.2)
       animation.CrossFade ("walk");
   else
      animation.CrossFade ("idle");
}

You just need to modify that to suit your purpose, for example:

function Update ()
{
   if (Input.GetMouseButton(0));
        animation.CrossFade ("Swing");
   else
        animation.CrossFade ("Idle");
}

What script must be?
if I want to play axe animation when mouse button pressed? and where that script must be attacthed?
