When I run game in device player velocity cannot zero when die in unity

Question

In my unity2D game run in device so player velocity set not zero when collide with ground and I use a FixedUpdate() function for player flap also my player flap on static position.

void FixedUpdate ()
{
    // Jump
    if (isAlive)
    {
        if (didFlap) {
            didFlap = false;
            myRigidbody.velocity = new Vector2(0,bounceSpeed);
            anim.SetTrigger ("Flap");
        }
    }if (myRigidbody.velocity.y >= 0) {
        transform.rotation = Quaternion.Euler (0, 0, 0);
    } else {
        float angle = 0;
        angle = Mathf.Lerp (0,-45,-myRigidbody.velocity.y/7f);
        transform.rotation = Quaternion.Euler (0, 0, angle);
    }
}
void OnCollisionEnter2D(Collision2D target)
{
    if (target.gameObject.tag=="Ground")
    {
         die();
    }
}
void die()
{
    if (isAlive) 
    {
        isAlive  = false;
        anim.Play ("Died");
        myRigidbody.velocity = Vector2.zero;
    }
}

Ok but there is no code of movement here and there you should search for problem. In `die()` you just set velocity to [0,0] but than some code will change velocity anyway. I can tell you more if you post part of code that is responsible for movement — Paweł Marecki, Jul 20 '16 at 06:30
As already stated, without code we can only guess. Here is mine, adding to what @PawełMarecki said: Are you setting the rigidbody's velocity in the `Update()` method? this is called after the OnCollision functions and would therefore overwrite the velocity of your `die()` function. (see execution order: https://docs.unity3d.com/Manual/ExecutionOrder.html) — nyro_0, Jul 20 '16 at 06:34
I try myRigidbody.velocity = new Vector2(0,0) but still player move on ground. — Chetan, Jul 20 '16 at 06:36
Show us your `Update` und `FixedUpdate` functions, otherwise we won't be able to help you — nyro_0, Jul 20 '16 at 06:39
Please, update your question with this code. Its really hard to read code like this. — Paweł Marecki, Jul 20 '16 at 07:00
You may try to set `myRigidbody.isKinematic` to `true`. Maybe there is something what make your's object move eg. gravity or bouncines on physics material. — Paweł Marecki, Jul 20 '16 at 07:50
more of a setup question: have you set your tags correctly -> is `die()` even called on collision? — nyro_0, Jul 20 '16 at 07:56

So if I am understanding this right you can still move the player around after they died in the game.

so what you need to do is when the player dies is make a Boolean that is true when the player dies

   void Update()
   {
        if (dead == false)
        {
            //player movement code hear 
        }
   }

this way if you are dead than you can't move because you player control code is not accessible.

I hope this helps.
