Creating new GameObject after destroying

Hi, As a beginner I'm trying to make a space shooter game. Currently the problem I'm facing is if "Spaceship" gameobject collide with "EnemyShip" gameobject 3 times after that spaceship isn't moving from it's place. How can I solve it.

Code (JavaScript):

1. public var bullet : GameObject;
2. public var spaceship : GameObject;
3.  
4. function Start () {
5.      
6. }
7.  
8. function Update () {
9.     rigidbody2D.velocity.x = Input.GetAxis("Horizontal")*10;
10.     rigidbody2D.velocity.y = Input.GetAxis("Vertical")*10;
11.    
12.     //When spacebar is pressed
13.     if(Input.GetKeyDown("space")){
14.         Instantiate(bullet, transform.position, Quaternion.identity);
15.     }
16. }
17. // Function called when the enemy collides with another object
18. function OnTriggerEnter2D(obj : Collider2D) {
19.     var name = obj.gameObject.name;
20.     // If it collided with the spaceship
21.     if (name == "enemy(Clone)") {
22.         Destroy(gameObject);
23.         Destroy(obj.gameObject);
24.         Debug.Log("HIT");
25.         createSpaceShip();
26.     }
27. }
28. function createSpaceShip(){
29.  
30.     var point = new Vector2(0,-4);
31.     Instantiate(spaceship, point, Quaternion.identity);
32. }

 

Not sure if that is your problem, but I think you shouldn't issue a Destroy(gameObject) until you are completely finished with the gameObject...

 

Hi Adnan,
I just worked out a fairly simple enemy instantiate and destroy solution, take a look and see if it is any help. It uses a random enemy instantiation (which you could simplify if you have only one type of entity) as well as a bullet detection script that destroys the enemy and then calls the instantiation script again. There is always one enemy.

As PGJ says, you don't want to destroy any enemies that have scripts or the script will be destroyed, so I put my instantiation script on an empty game object.

I also have an example where you can destroy an object with four hits:

Your problem is you instantiate your object on a position you just erased, try instantiating the new object on the old position before you delete the gameobject holding the position.

 

Just a suggestion, it is easier on performance if you instantiate a bunch of enemies at the beginning and then deactivate them with GameObject.SetActive(false) when they die. That way you can reuse them without Unity having to recreate them from scratch.
