I am trying to get the score to reset back to zero in an asteroids like game I am programming.
So I got the score to increase every time I destroy an enemy. But I can't seem to get the score to reset back to zero when all enemies on screen have been destroyed. Someone help me out please. Here is my code.
using UnityEngine; using System.Collections;
public class Rock : MonoBehaviour { public int movementSpeed = 2; GameManager gm; public int score; public Vector3 sizepos;
// Use this for initialization
void Start ()
{
sizepos = this.transform.localScale;
transform.Rotate (0.0f, 0.0f, Random.Range (0.0f, 360.0f));
gm = GameObject.Find ("GameManager").GetComponent<GameManager> ();
}
// Update is called once per frame
void Update ()
{
if (this.gameObject == null) {
gm.score = 0;
}
//rigidbody2D.AddForce (transform.up * movementSpeed * Time.deltaTime);
transform.Translate (Vector3.up * Time.deltaTime * movementSpeed);
}
void OnTriggerEnter2D (Collider2D other)
{
if (!other.gameObject.CompareTag ("Rock")) {
if (this.transform.localScale.x > 0.25f) {
for (int i = 0; i < 2; i++) {
gm.Rock (this.transform.position, this.transform.localScale.x / 2.0f);
}
}
Destroy (this.gameObject);
if (this.transform.localScale.x >= 0.25f && this.transform.localScale.x <= 0.25f) {
gm.score += 100;
Debug.Log ("score:" + score);
}
if (this.transform.localScale.x >= 0.5f && this.transform.localScale.x <= 0.5f) {
gm.score += 50;
Debug.Log ("score:" + score);
}
if (this.transform.localScale.x >= 1f && this.transform.localScale.x <= 1f) {
gm.score += 20;
}
}
}
}

By definition this.gameObject will never be null. Hence score will never be reset.
To get a score that resets try the following
// On the GameManager Component
public int Count;
Update () {
// Do whatever
if (Count<=0){
Score = 0;
}
// Do some other stuff
}
// On the asteroid
Start(){
// The other start stuff
gm.Count++;
}
void OnTriggerEnter2D (Collider2D other){
// Do the other stuff
gm.Count--;
destroy(gameObject);
// Do not do anything here, it will not run
}
Incidentally the this is implicit in MonoBehavior for gameObject and transform.
Also nothing will run after line 34, destroyed GameObjects stop running all code as soon as destroy is called
