using System.Collections; using System.Collections.Generic; using UnityEngine;

public class BirdMovement : MonoBehaviour {

[SerializeField]
private Transform target;
private UnityEngine.AI.NavMeshAgent birdAgent;
private Animator birdAnimator;

// Use this for initialization
void Start () {

    birdAgent = GetComponent<UnityEngine.AI.NavMeshAgent> ();
    birdAnimator = GetComponent<Animator> ();

}

// Update is called once per frame
void Update () {

    birdAgent.SetDestination (target.position);

    // Measure the magnitude of the NewMeshAgent's velocity
    float speed = birdAgent.velocity.magnitude;

    //Pass the velocity to Animator component
    birdAnimator.SetFloat("Speed", speed);

The 5f is suppose to be to destroy the pick particles after 5 seconds

I am not familiar with unity or C#, which is what I think you're using here, but what you've written reads

if (the object is an enemy and it is alive, then its state should be set to true). Else, the state of the object should be set to false. So why are you then assigning false to alive in your OnTriggerEvent? I think this might be where your error lies, but I can't compile your code to check it for myself right now.

Also, you're destroying the gameObject after 5 seconds, which is probably why the frog is disappearing after that amount of time has expired. Are you trying to keep the frog on screen until it is eaten? Can you be a little more specific with what you're code is supposed to accomplish?

Ok, that's what I figured. Correct me if I'm wrong then, but if the object is an Enemy, and the frog is alive, you want the frog object to be destroyed. Right? If that's the case, you need to add some more code. You need to assign the value of alive (in this case false) to the frog, and then define what happens to the frog when it's state is false (or dead). Otherwise, if the frog is in a living state, nothing should happen to it. As for the bird, it looks like you might need a for loop. How long do you want it to walk?
