更改 Gizmos.DrawWireCube 多维数据集限制，基于子项 transform.position

Change Gizmos.DrawWireCube Cube Limits, based in childs transform.position

问：

如何更改基于子变换 （Gizmos.DrawWireSphere） 的 Gizmos.DrawWireCube 的宽度 transform.position 或变换的左/右限制？

到目前为止，我的代码：

位置.cs

using UnityEngine;
using System.Collections;

public class Position : MonoBehaviour {
    void OnDrawGizmos () {
        Gizmos.DrawWireSphere(transform.position, 0.75f);
    }


}

编队控制器：.cs

using UnityEngine;
using System.Collections;

public class FormationController : MonoBehaviour {
    public GameObject enemyPrefab;
    public float width = 10;
    public float height = 5;
    public float speed = 5;
    public float padding = 1.5f;
    public float SpawnDelaySeconds = 1;
    private int direction = 1;
    private float boundaryLeftEdge,boundaryRightEdge;
    private PlayerController playerController;
    // Use this for initialization

    void Start () {
        float distance = transform.position.z - Camera.main.transform.position.z;
        Vector3 leftmost = Camera.main.ViewportToWorldPoint(new Vector3(0, 0, distance));
        Vector3 rightmost = Camera.main.ViewportToWorldPoint(new Vector3(1, 0, distance));
        boundaryLeftEdge = leftmost.x + padding;
        boundaryRightEdge = rightmost.x - padding;
        SpawnUntilFull();
    }



    void OnDrawGizmos () {
        Gizmos.DrawWireCube(transform.position, new Vector3 (width, height));
    }

    // Update is called once per frame
    void Update () {
        float formationRightEdge = transform.position.x + 0.5f * width;
        float formationLeftEdge = transform.position.x - 0.5f * width;
        if (formationRightEdge > boundaryRightEdge) {
            direction = -1;
        }
        if (formationLeftEdge < boundaryLeftEdge) {
            direction = 1;
        }
        transform.position += new Vector3(direction * speed * Time.deltaTime, 0, 0);
        if (AllEnemiesAreDead()) {
            SpawnUntilFull();
        }
    }

    void SpawnUntilFull () {
        Transform freePos = NextFreePosition();
        GameObject enemy = Instantiate(enemyPrefab, freePos.position, Quaternion.identity) as GameObject;
        enemy.transform.parent = freePos;
        if (FreePositionExists()) {
            Invoke ("SpawnUntilFull", SpawnDelaySeconds);
        }

    }

    bool FreePositionExists () {
        foreach( Transform position in transform) {
            if (position.childCount <= 0) {
                return true;
            }
        }
        return false;
    }

    Transform NextFreePosition() {
        foreach (Transform position in transform) {
            if (position.childCount <= 0) {
                return position;
            }
        }
        return null;
    }

    bool AllEnemiesAreDead () {
        foreach(Transform position in transform) {
            if (position.childCount > 0) {
            return false;
            }           
        }
        return true;
    }
}

举个例子：

我正在制作一款类似“太空入侵者”的游戏，但我无法弄清楚当最左边的入侵者死亡时，入侵者的阵型如何变成更小的阵型......因此，新的最左翼入侵者“触及”了左翼边界。

我的场景：

忽略最顶部的小玩意儿（圆圈）

当左边的入侵者死去时：你是想让盒子变小，以便它从下一个左边的入侵者开始，还是想把下一个左边的入侵者移得更左？

@JinJi也许......第一个。我想要的是它们左右移动，并且始终触摸相机的边缘（忽略填充）......当最左边的入侵者死去时：新的最左边的入侵者最左边，或者更准确地说是整个阵型

当玩家杀死最多的左/右入侵者（敌人）时，矩形小玩意儿的宽度会变小

你的第一条评论说敌人必须移动，盒子不能改变。你的第二条评论说盒子必须改变。

@JinJi对不起，我的英语拼写不是很好......盒子必须改变，以便形成接触左右边缘

试试这个：

using UnityEngine;
using System.Collections;

public class FormationController : MonoBehaviour {
    public GameObject enemyPrefab;
    public float widthToLeft = 5;
    public float widthToRight = 5;
    public float height = 5;
    public float speed = 5;
    public float padding = 1.5f;
    public float SpawnDelaySeconds = 1;
    private int direction = 1;
    private float boundaryLeftEdge,boundaryRightEdge;
    private PlayerController playerController;
    // Use this for initialization

    void Start () {
        float distance = transform.position.z - Camera.main.transform.position.z;
        Vector3 leftmost = Camera.main.ViewportToWorldPoint(new Vector3(0, 0, distance));
        Vector3 rightmost = Camera.main.ViewportToWorldPoint(new Vector3(1, 0, distance));
        boundaryLeftEdge = leftmost.x + padding;
        boundaryRightEdge = rightmost.x - padding;
        SpawnUntilFull();
    }



    void OnDrawGizmos () {
        Gizmos.DrawWireCube(transform.position, new Vector3 (widthToLeft+widthToRight, height));
    }

    // Update is called once per frame
    void Update () {
        float formationRightEdge = transform.position.x + 0.5f * widthToRight;
        float formationLeftEdge = transform.position.x - 0.5f * widthToLeft;
        if (formationRightEdge > boundaryRightEdge) {
            direction = -1;
        }
        if (formationLeftEdge < boundaryLeftEdge) {
            direction = 1;
        }
        transform.position += new Vector3(direction * speed * Time.deltaTime, 0, 0);
        if (AllEnemiesAreDead()) {
            SpawnUntilFull();
        }
    }

    void SpawnUntilFull () {
        Transform freePos = NextFreePosition();
        GameObject enemy = Instantiate(enemyPrefab, freePos.position, Quaternion.identity) as GameObject;
        enemy.transform.parent = freePos;
        if (FreePositionExists()) {
            Invoke ("SpawnUntilFull", SpawnDelaySeconds);
        }

    }

    bool FreePositionExists () {
        foreach( Transform position in transform) {
            if (position.childCount <= 0) {
                return true;
            }
        }
        return false;
    }

    Transform NextFreePosition() {
        foreach (Transform position in transform) {
            if (position.childCount <= 0) {
                return position;
            }
        }
        return null;
    }

    bool AllEnemiesAreDead () {
        foreach(Transform position in transform) {
            if (position.childCount > 0) {
            return false;
            }           
        }
        return true;
    }
}

我刚刚将宽度更改为 widthToLeft 和 widthToRight

当入侵者死亡时：

public void OnInvaderDeath() {
    float mostLeft = 10000;
    float mostRight = -10000;
    foreach( Transform invaderTransform in invaderList ) {
        if( invaderTransform.position.x < mostLeft )
            mostLeft = invaderTransform.position.x;
        if( invaderTransform.position.x > mostRight )
            mostRight = invaderTransform.position.x;
    }
    widthToLeft = mostLeft + 0.75f;
    widthToRight = mostRight + 0.75f;
}

我试过了，并进行了一些修改，因为 OnInvaderDeath 在另一个脚本上......但没有用。我会尝试适应这一点，我会很快发布通知。谢谢
