Fixed it by doing a workaround
Instantiating GameObject and Adding to list
So like the title says I am trying to instantiate an GameObject and add it to a list, in this case it's to manage the gameobjects because I do not want to many in my scene. Code:
void Start () {
for(int x = 0; x < MaxAmountWolfs; x++)
{
GameObject wolf= Instantiate(Wolfs);
Spawn.Random(wolf); // this is just another class that I use to give the object a random spawn location within the navmesh boundaries.
lstWolfs.Add(new AIAnimal { Animal = wolf});
}
Debug.Log(lstWolfs.Count);
foreach(AIAnimal animal in lstWolfs)
{
Debug.Log(animal.name);
}
}
The objects spawn just fine and they appear in the hierarchy which is good. however when I debug the list all the objects are null... which makes absolutely no sense to me.
The class AIAnimal is simply:
public class AIAnimal : MonoBehaviour {
public GameObject Animal { get; set; }
}
I probably making some stupid mistake, I just don't see it.
This should work :
void Start () {
for(int x = 0; x < MaxAmountWolfs; x++) {
GameObject wolf = Instantiate(Wolfs) as GameObject; //Instantiante the wolf.
lstWolfs.Add(wolf); //Add it to your list
Spawn.Random(wolf); //Spawn it somewhere
new AIAnimal { Animal = wolf} //Set the AI
}
}
Add the instantiated GameObject instead of the AI.
I havent tried that but that makes no sense, AIAnimal contains just set and get properties, and as soon as I spawn it it's not null so why would it become null when I add it to the list. also the list is declared as :
List<AIAnimal> lstwolfs = new List<AIAnimal>();
So it expects an AIAnimal class, not just a gameobject... so adding wolf won't work :)
What if the list was set for GameObjects? You could still access the your wolves in the list.
Using "new" for components is not recommended, you have to use GameObject.AddComponent method.
Something like this...
for(int x = 0; x < MaxAmountWolfs; x++)
{
GameObject wolf= Instantiate(Wolfs);
Spawn.Random(wolf);
AIAnimal aiComponent = wolf.AddComponent<AIAnimal>();
aiComponent.Animal = wolf;
lstWolfs.Add(aiComponent);
}
Also, that "Animal" variable inside the AIAnimal class looks redundant... why not just use gameObject? Every MonoBehaviour has the "gameObject" field that's a reference to the GameObject it's attached.
Yeah that's how I temporarely fixed it myself just by making the list of type GameObject, however I was gonna add more properties to the AIAnimal but I will just do a workaround...
By the way the weird thing is that it did work before. It did return null for every item AIAnimal in the list but after a certain amount of frames they were not null anymore. I think it may have to do with the script execution order.
