How to get all gameObjects with a script on them
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.
I don't get where/how to reference it in the foreach function with the script you made (also thank you).
