Destroy multiple game objects when player press a button

Questions & Answers

Hi
I am new to C# and Unity. I have searched the web and I am finding it hard to implement a game mechanic. I am working on a mechanic which takes away health to perform a special move. This special move will destroy all enemies with a certain tag, however I am not sure how to do this.

I have came across FindGameObjectsWithTag but as I have said I am not sure how to implement this. I have read the Unity script reference and not sure how to take whats there and put it in my code. If it helps heres the code I have at the moment.

	if (Input.GetKeyDown (KeyCode.Keypad8) & shieldHealth > 50)
	{
		shieldHealth -=50;
		
		print ("I have enough health");
	}

Any help is greatly appreciated. Thanks in advance.

this can help you destroy all object with same tag on key press you just need to set a partical affect to go off at the same time to look like an attack

var Enemies: GameObject;//declares an array of GameObjects
//to be filled later

function Start()
{
     Enemies = GameObject.FindGameObjectsWithTag("Enemy");
     //fill the Enemies array with actual enemy GameObjects
     //"Enemy" is the tag your enemies have
}

function Update()
{
     if (Input.GetKeyDown (KeyCode.Keypad8) & shieldHealth > 50)
     {
          shieldHealth -=50;
          for(var EnemyCurrent in Enemies)
          //iterates (loops) through your array, EnemyCurrent is a temporary 
          //variable given to the current array entry each loop start
          {
               Destroy (EnemyCurrent);//Destroys the current enemy object
          }
          print ("I have enough health");
      }
 }
