How to play an animation all the way through on a single key

======================================================================================================================================================

var die1 : boolean;

var die2 : boolean; 

function Update() 

{

 if (Input.GetKeyDown(KeyCode.Alpha1))

 { die1 = true; 

die2 = false; 

} 

if (die1) 

{

 animation.CrossFade("die1"); 

animation.wrapMode = WrapMode.ClampForever; 

} 

if (Input.GetKeyDown(KeyCode.Alpha2)) 

{ die2 = true; die1 = false; }

 if (die2)

 { animation.CrossFade("die2"); 

animation.wrapMode = WrapMode.ClampForever; }

 else { 

animation.CrossFade("idle"); 

animation.wrapMode = WrapMode.Loop;

 } 

}

==================================================================================================================================================

if (die1) 

{

 if(animation.IsPlaying("die1"))

{ }

else

{

 animation.Play("die1"); 

} 

}

==================================================================================================================================================

the above code can be used to get an animation to play out fully without stopping on a single key press and even when you press the key again it shouldn't play, just double check that my "IsPlaying" method is used correctly

This seems to work just fine. Thank you all for your help.

function Start() 

{ 

animation["die1"].layer = 1; 

animation["die2"].layer = 1;

 } 

function Update() 

{ 

if (Mathf.Abs(Input.GetAxis("Vertical")) > 0.2)

 { 

animation.Stop("die1");

 animation.Stop("die2");

 if (Mathf.Abs(Input.GetAxis("Run")) > 0.2) 

{

 animation.CrossFade("run"); } 

else 

{ 

animation.CrossFade("walk");

 } } 

else if 

(Input.GetButton("Fire1"))

 {

 animation.Stop("die1");

 animation.Stop("die2"); 

animation["attack1"].wrapMode = WrapMode.Once; animation.Play("attack1"); 

} 

else if (Input.GetButton("Fire2")) 

{ 

animation.Stop("die1");

 animation.Stop("die2");

 animation["attack2"].wrapMode = WrapMode.Once;

 animation.Play("attack2"); 

} 

else if (Input.GetKeyDown(KeyCode.Alpha1)) 

{ 

animation["die1"].wrapMode = WrapMode.ClampForever; 

animation.CrossFade("die1"); 

} 

else if (Input.GetKeyDown(KeyCode.Alpha2))

 {

 animation["die2"].wrapMode = WrapMode.ClampForever; animation.CrossFade("die2"); 

} else { animation.CrossFade("idle"); 

}

 }
