Instantiate GameObject
Hello,
I am getting error in my script where I try to instantiate game object:
public int mapL, mapH;
public Transform[,] mapTransform;
void Start ()
{
mapL = 10;
mapH = 10;
mapTransform = new Transform[mapL,mapH];
Stuff();
}
void Stuff()
{
mapTransform[i,j]=Transform.Instantiate(grassButton, new Vector2(i,j), transform.rotation);
}
Cannot implicitly convert type UnityEngine.Object to UnityEngine.Transform. An explicit conversion exists (are you missing a cast?)
Same if I use public GameObject[,] mapTransform: Cannot implicitly convert type UnityEngine.Object to UnityEngine.GameObject. An explicit conversion exists (are you missing a cast?)
Can anyone tell me what I am doing wrong?
You can fix that by using casts (boxing or the 'as' keyword).
someTransform = (Transform)Instantiate(....);
or
someTransform = Instantiate(...) as Transform;
The difference is, that 'as' might return null when the object cannot be casted, whereas the boxing approach would throw an InvalidCastException.
Don't count this as "Expert" advice, since I'm struggling with similar issues, but on the instantiating materials on the instantiated geo. But I think you're better off doing the whole thing as a GameObject, as a transform has to have a "Parent" to live under, and GameObject is the lowest common denominator, and most likely what Unity is complaining about...
