尝试实例化 object 时无法将类型“UnityEngine.GameObject”隐式转换为“UnityEngine.Vector2”

Question

I am trying to make a section of a Unity game where balloons will spawn within the bounds of a box collider. This is done randomly. However, I am having trouble Instantiating the prefab. I have tried two methods, with the same error being thrown for both.

This is the first method, here I used GameObject.transform .

for(int i = 0; i > numBalloons; i++){
            float randomX = Random.Range(left, right);
            float randomY = Random.Range(up, down);

            balloons[i] = Instantiate(BalloonPrefab, BalloonPrefab.transform);
        }

This was the second method, where I used a Vector2 and Quaternion to try and initialize the object:

for(int i = 0; i > numBalloons; i++){
            float randomX = Random.Range(left, right);
            float randomY = Random.Range(up, down);

            Vector2 temp = new Vector2(randomX, randomY);

            balloons[i] = Instantiate(BalloonPrefab, temp, Quaternion.identity);
        }
    }

For both methods, I get the following error: Cannot implicitly convert type 'UnityEngine.GameObject' to 'UnityEngine.Vector2' . This is confusing me beyond belief, because if I make BalloonPrefab a Vector2 (which didn't seem to be a solution but was a worthy test), it asks for an object, and if I make it an object, it seems to want a Vector2. Does anyone know what the issue could be?

Answer 1

I Think your For condition is also wrong and array think so

public GameObject BalloonPrefab,ballon_parent;

public GameObject[] balloons;

void Start()
{
    for (int i = 0; i < numBalloons; i++)
    {
        float randomX = Random.Range(left, right);
        float randomY = Random.Range(up, down);

        Instantiate(BalloonPrefab, new Vector2(randomX, randomY),Quaternion.identity, ballon_parent.transform);
    }
}
