How to disable "GameObject" Then Enable After Animation.

One way to work through something like this (in any programming challenge actually) is think about every step that needs to occur:

1. You need to have a GameObject assigned for the QuickStab

2. You need to initially disable the renderers on it

3. Wait for the input of the "V" key

4. Once pressed enable the renderers

5. Play the animation

6. Check to see if the animation is complete

7. Disable the renderers

So one way to do it would be to create a script specifically for this object "QuickStab" object and place it on the object:

 Renderer[] renderers;
 string stabAnimation = "StabAnimation";
     
 void Start()
 {
     //get the renderers and store for later use
     renderers = GetComponentsInChildren<Renderer>();
     
     //turn off renderers initially
     foreach(Renderer r in renderers)
     {
         r.enabled = false;
     }
 }
 
 void Update()
 {
     //if V is pressed and we are not playing the animation
     if(Input.GetKeyDown(KeyCode.V) && !animation.IsPlaying(stabAnimation))
     {
         //turn on renderers and start playing the animation
         foreach(Renderer r in renderers)
         {
             r.enabled = true;
         }
         
         //play the animation
         animation.Play(stabAnimation);
     }
     //if we are playing the animation
     else if (animation[stabAnimation].time <= animation[stabAnimation].length)
     {
         //if we are playing and not at the end of the animation
         if(animation.IsPlaying(stabAnimation))
         {
             //do something like check for raycast hits
         }
         //we are at the end of the animation
         else
         {
             //ensure animation stops
             animation.Stop(stabAnimation);
             
             //disable renderers
             foreach(Renderer r in renderers)
             {
                 r.enabled = false;
             }
         }
     }
 }

This is just one of many ways to accomplish something like this. Sorry it's in C#. I'm a C# guy.

Here's my attempt to put it in JavaScript:

 var renderers : Renderer[];
 var stabAnimation : string = "StabAnimation";
     
 function Start()
 {
     //get the renderers and store for later use
     renderers = GetComponentsInChildren(Renderer);
     
     //turn off renderers initially
     for(var x : int = 0; x < renderers.length; x++)
     {
         r.enabled = false;
     }
 }
 
 function Update()
 {
     //if V is pressed and we are not playing the animation
     if(Input.GetKeyDown(KeyCode.V) && !animation.IsPlaying(stabAnimation))
     {
         //turn on renderers and start playing the animation
         for(var x : int = 0; x < renderers.length; x++)
         {
             r.enabled = true;
         }
         
         //play the animation
         animation.Play(stabAnimation);
     }
     //if we are playing the animation
     else if (animation[stabAnimation].time <= animation[stabAnimation].length)
     {
         //if we are playing and not at the end of the animation
         if(animation.IsPlaying(stabAnimation))
         {
             //do something like check for raycast hits
         }
         //we are at the end of the animation
         else
         {
             //ensure animation stops
             animation.Stop(stabAnimation);
             
             //disable renderers
             for(var x : int = 0; x < renderers.length; x++)
             {
                 r.enabled = false;
             }
         }
     }
 }
