Destroy within a certain radius?

Hello. When a condition happens, I want to destroy all objects with a certain tag that are within a certain radius of another object immediately, how would I do this? Thank you

 

Try something like this:

Code (csharp):

1.  
2. var explosionPosition = transform.position;
3. var explosionRadius: float = 10.0;
4. var colliders : Collider[] = Physics.OverlapSphere(explosionPosition, explosionRadius);
5. foreach (var col in colliders)
6.     {
7.       if (col.collider.tag == "enemy")
8.       {
9.         Destroy(col.collider.gameObject);
10.       }
11.     }
12.  

You have to check the JavaScript format.

 

I know this is a noob thing to say, but how would I implement that script? I want to destroy the enemies in the radius after the player collides with that an enemies, so would it be something like this?

Code (csharp):

1. var explosionPosition = transform.position;
2. var explosionRadius: float = 10.0;
3. var colliders : Collider[] = Physics.OverlapSphere(explosionPosition, explosionRadius);
4.  
5. function OnTriggerEnter (other : Collider) {
6.     if (other.gameObject.CompareTag ("Enemy")) {
7.        Stats.Life -=1;
8. foreach (var col in colliders)
9.     {
10.       if (col.collider.tag == "Enemy")
11.       {
12.         Destroy(col.collider.gameObject);
13.       }
14.     }
15.     }

 

My original code is intended for attaching to an explosion game object, such as grenade. Therefore, just attached the code to a explosion object and any objects within that radius you should destroy.

Now, your code is a trigger. A trigger is fired when one game object collided with another game object. In this case, a player can only collide with one enemy at a time. How do you expect to kill all enemies with a radius? That does not make a lot sense in term of visual.

Does the player have some kind of power, such a magic?

 

Okay. I actually want to use this code to help with the player respawn process. When the player gets hit, I want to destroy all objects that have the "Enemy" tag that are surrounding the player.

 

OK, if you still insisted. I think that the following script will do what you want:

1) attach a collider to each enemy and check mark Is Trigger property
2) attach the following script to each enemy

I hope that you create an enemy prefab

C#

Code (csharp):

1.  
2. public float radius = 10.0f;
3.   // Use this for initialization
4.   void Start()
5.   {
6.  
7.   }
8.  
9.   void OnTriggerEnter(Collider other)
10.   {
11.     if (other.gameObject.CompareTag("Player"))
12.     {
13.       Stats.Life -=1;
14.       print("collided");
15.       Collider[] colliders = Physics.OverlapSphere(other.gameObject.transform.position, radius);
16.       foreach (Collider col in colliders)
17.       {
18.         if (col.tag == "Enemy")
19.         {
20.           Destroy(col.gameObject);
21.         }
22.       }
23.     }
24.   }
25.   // Update is called once per frame
26.   void Update()
27.   {
28.  
29.   }
30.  

JavaScript

Code (csharp):

1.  
2.  var radius: float = 10.0;
3.   // Use this for initialization
4.   function Start()
5.   {
6.  
7.   }
8.  
9.   function OnTriggerEnter(other: Collider)
10.   {
11.     if (other.gameObject.CompareTag("Player"))
12.     {
13.       Stats.Life -=1;
14.       print("collided");
15.       var colliders: Collider[]  = Physics.OverlapSphere(other.gameObject.transform.position, radius);
16.       for (var col: Collider in colliders)
17.       {
18.         if (col.tag == "Enemy")
19.         {
20.           Destroy(col.gameObject);
21.         }
22.       }
23.     }
24.   }
25.   // Update is called once per frame
26.   function Update()
27.   {
28.  
29.   }
30.  

 

Whats a prefa...nah im just kidding
