Character selection
Hello, does anyone know how to make a character selection like the one in the Ballz mobile game? I have watched a YouTube tutorial on how to do it and came up with this script :
private List<GameObject> balls;
private int selectionIndex = 0;
private void Start()
{
balls = new List<GameObject>();
foreach(Transform t in transform)
{
balls.Add(t.gameObject);
t.gameObject.SetActive(false);
}
balls[selectionIndex].SetActive(true);
}
private void Update()
{
}
public void Select(int index)
{
if (index == selectionIndex)
return;
if (index < 0 || index >= balls.Count)
return;
balls[selectionIndex].SetActive(false);
selectionIndex = index;
balls[selectionIndex].SetActive(true);
}
Now, instead of the gameobjects to get inactive, what I want instead is to change the outline color of the gameobjects and change a text inside the gameobject. How would I do that? I'm still new to coding and have no idea.
Most likely you'd like to add a component to the balls, something like BallSelectionBehaviour.
In that script you could have a public method called OnBallSelected(), where you'd do everything that you want, including the SetActive().
And finally, in your script, you would call balls[selectionIndex].GetComponent<BallSelectionBehaviour>.OnBallSelected() instead of the set active.
Note that GetComponent<> can get a bit heavy. It might be a good idea to store the BallSelectionBehaviour in a list, just like you did with the GameObject, and populate the list only once on Start. Another option would be a Dictionary<GameObject, BallSelectionBehaviour>.
From what I see, I'd also create a OnBallDeselected() and add there the SetActive(false). It is a good idea to have your things separated. So, next time you want to add some particles, e.g., when a ball is selected, you know exactly where to change the code.
Hello, thank you for your reply. When I change the balls[selectionIndex].SetActive(true); to balls[selectionIndex].GetComponent.OnBallSelected(); it gives me an error - Expression denotes a method group', where a variable', value' or type' was expected.
You need to specify which component you want to get. In the case of my example, it would be balls[selectionIndex].GetComponent<BallSelectionBehaviour>().OnBallSelected(). Ins$$anonymous$$d of BallSelectionBehaviour just put the name of the $$anonymous$$onoBehaviour you have attached to the ball with the public method OnBallSelected().
Oh gosh, I'm stupid! Yeah, I'll try, thanks.
