How to randomly select multiple gameobjects from array?

Questions & Answers

Hi guys. I’m a newbie. I want to select multiple game objects from a list of array that i have stored, and no 2 game objects are the same. This is the code that I have written.

void PlaneDisappear()
    {
        randomGround = GameObject.FindGameObjectsWithTag("Ground");

        iOne = Random.Range(0, randomGround.Length);

        iTwo = Random.Range(0, randomGround.Length);
        while (iOne == iTwo)
        {
            iTwo = Random.Range(0, randomGround.Length);
        }

        iThree = Random.Range(0, randomGround.Length);
        while (iOne == iTwo || iOne == iThree || iTwo == iThree)
        {
            iThree = Random.Range(0, randomGround.Length);
        }

        disappearGroundOne = randomGround[iOne];
        disappearGroundTwo = randomGround[iTwo];
        disappearGroundThree = randomGround[iThree];
       
        disappearGroundOne.active = false;
        disappearGroundTwo.active = false;
        disappearGroundThree.active = false;
    }

Surely there is an easier and simpler way. Can anyone help? Thanks and appreciate it!

randomGround = GameObject.FindGameObjectsWithTag(“Ground”);
for(int i=0; i<3; i++){
int index = Random.Range(0, randomGround.Length);
randomGround[index].active = false;
randomGround.RemoveAt(index);
}
