How to get all gameObjects with a script on them

Questions & Answers
1

I want all my images on a canvas to rotate 180 degrees when the turn ends but I dont want to choose what cards chnage based on Tags because I needs those for later use, I put a script on all the cards called “PlayingCard” and this is my script currently:

public class EndTurn : MonoBehaviour
{
// public PlayingCard GameCards;

private void Start()
{
   
} 


private void Update()
{
    //GameCards = GetComponentsInChildren<RectTransform>();
}

private void OnGUI()
{
    if (GUI.Button(new Rect(650, 10, 100, 20), "End Turn"))
    {
        PlayingCard[] GameCards = FindObjectsOfType(typeof(PlayingCard)) as PlayingCard[];
        foreach (PlayingCard component in GameCards)
        {
           // RectTransform rectTransform = GetComponent<RectTransform>();
            transform.Rotate(new Vector3(0, 0, 45));
        }
    }
}

}

Hi @ZachBoi ,

To get all gameObjects with a specifc script on them you can use the method Object.FindObjectsOfType

Exemple:

PlayingCard[] playingCardArray  = Object.FindObjectsOfType<PlayingCard>();

After that you can accesse the GameObjects via:

playingCardArray[index].gameObject

But keep in mind that Object.FindObjectsOfType is a very slow function. So calling it many times per frame is not a good ideia. If you need to do this more frequently, I would recomend you to create a singleton controller script with a list of PlayingCard, and then have each new instance of PlayingCard putting their own reference in the controller’s list.
