随机实例化预制件,但不在已经生成的位置

Question

我想在我的屏幕中随机生成气泡.当气泡在一个地方产生时,其他气泡不能在其半径1区域附近产生.表示气泡不会与任何其他气泡碰撞或触发.

我该怎么做 ？

public void GenerateBubble ()
        {
                newBubbleXPos = Random.Range (-7, 7);
                newBubbleYPos = Random.Range (-3, 3);
                bubbleClone = (GameObject)Instantiate (bubblePrefab, new Vector3 (newBubbleXPos, newBubbleYPos, 0), Quaternion.identity);
                UIManager.instance.ChangeBubbleSprite (bubbleClone);
                bubbleList.Add (bubbleClone);
                if (bubblePosList.Contains (bubbleClone.transform.position)) {
                    bubbleClone.transform.position=new Vector3(Random.Range (-7,7),Random.Range (-3,3),0);
                }
                bubblePosList.Add (bubbleClone.transform.position);
                bubbleClone.transform.parent = UIManager.instance.CurrentLevel.transform;
                GLOBALS.bubbleCounter++;
        }

在我的代码中,每个气泡都生成在不同的位置,但它可以与其他气泡碰撞,我想生成新的气泡不同的位置,也不会碰撞.我的泡泡对手的半径是1.

我找到了答案：

    public List<GameObject> bubbleList = new List<GameObject> ();
    private int newBubbleXPos;
    private int newBubbleYPos;

public void GenerateBubble ()
    {
        bool locationInvaild = true;
        while (locationInvaild) {
            newBubbleXPos = Random.Range (-8, 8);
            newBubbleYPos = Random.Range (-4, 4);
            currentPosition = new Vector3 (newBubbleXPos, newBubbleYPos, 0);
            locationInvaild = false;
            for (int i=0; i<bubbleList.Count; i++) {
                if (Vector3.Distance (bubbleList [i].transform.position, currentPosition) < 2.5f * radius) {
                    locationInvaild = true;
                    break;
                }
            }
        }
        bubbleClone = Instantiate (bubblePrefab, new Vector3 (newBubbleXPos, newBubbleYPos, 0), Quaternion.identity) as GameObject;
        bubbleList.Add (bubbleClone);
    }
