List Of GameObjects , Deleting these Objects !
i add objects in Run Time to a -> List();
fruits.Add((GameObject)Instantiate(fruit,transform.position, Quaternion.identity));
OnTriggerEnter() i destroy the Collider GameObject, which is a GameObject inside that list
void OnTriggerEnter(Collider col)
{
Destroy(col.gameObject);
}
Now my Question is, once i destroy it, will it also be removed from the List, Or i have to manually remove it from the List by accessing it...
The list will remain the same length- the destroyed gameObject will be replaced with a null reference. So, neither? I would recommend removing it manually before it gets destroyed, though- that would reduce confusion.
So if i say this fruits.Remove(col.gameObject);
will it be destroyed :D ?
or i have to do this
fruits.Remove(col.gameObject); Destroy(col.gameObject);
??
Thanks for helping.
You have to both remove it from the list, and also destroy it. They are two separate operations which do not directly affect one another, but you can only do them in one order (otherwise the object won't exist, so you won't be able to remove it from the list).
Its easier way to do it. Destroy all object in list and then use Delegate to clear all null object in list
SomeList.RemoveAll (delegate (GameObject o) { return o == null; });
Well, actually it's not easier since it's way longer than SomeList.Remove(item);. However if you can Destroy multiple objects at once, it would be more efficient since RemoveAll iterates through the list only once.
Here's a shorter version:
SomeList.RemoveAll((o)=>o == null);
