I want to make a melee comblat. Now I used the OnControllerColliderHit to work between my character and enemy. But the problem before the script is counting in many time when my character is playing the attack animation. So now I but the cool down timer to prevent it. Finally is ok, but now the problem is the animation between the combo. Sometime the enemy hitted animation will play when I start the combo 2, but sometime will not. What is the problem? Is it the script or animation problem?

below is the script I put

function OnControllerColliderHit (hit : ControllerColliderHit) {
   var myFPSPlayer : CharacterController;
   myFPSPlayer = gameObject.GetComponent(CharacterController);
    if (attackid > 0)
        {
        attackid -= Time.deltaTime;
        }
    if (attackid < 0)
        attackid = 0;
   if (myFPSPlayer)
      Debug.Log ("myFPSPlayer component found");
   if (hit.gameObject.tag == "Enemy" && Input.GetKeyDown("j"))
   {
    if (attackid == 0)
    {
      Debug.Log ("gameObject with tag evil found");
      ApplyDamage(hit.gameObject);
      attackid = coolDown;
    }
   } else {
   Debug.Log (hit.gameObject.name+" don't have tag evil, his tag is "+hit.gameObject.tag);
    }   
}

function ApplyDamage(someObject : GameObject)
{
   var healthScript = someObject.GetComponent("HealthScript");
   if (healthScript != null && animation.IsPlaying("attack1") )
   {
   someObject.animation.CrossFade("hit",0.2);
      healthScript.Health -= 10;
      Debug.Log ("A");
    }
     if (healthScript != null && animation.IsPlaying("attack2") )
   {
   someObject.animation.Play("hit");
      healthScript.Health -= 10;
      Debug.Log ("B");
    }
     if (healthScript != null && animation.IsPlaying("attack3") )
   {
   someObject.animation.Play("hit");
      healthScript.Health -= 10;
      Debug.Log ("C");
    }

if (healthScript != null && animation.IsPlaying("attack4"))
    {
    someObject.animation.CrossFade("die",0.2);
    healthScript.Health -= 10;
    Debug.Log ("D");
    }
}

Also, if I want to work melee comblat, I use colliderhit to do or use physics.raycast to do is better?

Can someone help me
