Frog can't catch new flies, only flies I placed myself in the hierarchy window.

Question

Here is the code:

using UnityEngine;
using System.Collections;

public class FlySpawner : MonoBehaviour {

    [SerializeField]
    private GameObject flyPrefab;

    [SerializeField]
    private int totalFlyMinimum = 12;

    private float spawnArea = 25f;

    public static int totalFlies;

    // Use this for initialization
    void Start () {
        totalFlies = 0;

    }

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

        //While the total number of flies is less than the minimum...
        while (totalFlies < totalFlyMinimum)
        {
            //... then increment the total number of flies
            totalFlies++;
            // ... create a random position for the fly
            float positionX = Random.Range(-spawnArea, spawnArea);
            float positionZ = Random.Range(-spawnArea, spawnArea);

            Vector3 flyPosition = new Vector3(positionX, 1.5f, positionZ);
            Instantiate(flyPrefab, flyPosition,Quaternion.identity);
        }



    }
}

Hello Yassin,

Thanks for providing access to the project. I've had a few minutes to look at it and here's what I found.

The reason the generated flies are not being picked up is because they are located too high on the Y axis. This explains why the collision detection is not firing when it looks like the frog is colliding with the flies. You can visualize this by playing the game in Unity and when the frog is near a fly, press the pause button and move the camera to see how high the fly is compared to the frog.

The source of the problem is some of the prefabs in the view were not at the default position. The environment itself was set to a negative number instead of 0. The player was also set too low on Y. Once I reset the positions, the flies could be reached by the frog as expected. I also fixed an exception that was being caused by an extra FlyMovement component that didn't have the center transform set.

You can download the updated project here. Please let me know when you've had a chance to download it :)

I hope this helps.
