Unity二维平面上物体的移动（十八）

上一节中实现了圆形机器人到达指定目标物体时，和目标物体打个招呼。实际情况是一个环境中会有很多物体，在出发前做一次整体扫描，了解环境中的整体物体数量和物体名称。我们随机做一下巡检，让物体在出发后按照扫描出来的顺序进行分析，逐一到达各个物体前。
下图圆形机器人位于环境中间偏左的位置。

从左侧列表中查看有14个物体是有效的，除去圆形机器人本身，需要扫描13个物体，并逐一到达他们跟前。
上代码菜，
public class AutoKnowObject : MonoBehaviour
{
GameObject my;
GameObject will;
GameObject[] GameObjectAll;
// Start is called before the first frame update
float ObjectsNum = 0;//全物体数量
float goalNum = 1;//目标物体数量
void Start()
{

    //找出所有物体对象
    GameObjectAll = AutoKnowObjectsAll();
    //Debug.Log(MyObjectName().name);

}

// Update is called once per frame
void Update()
{
//移至各个物体处
  //  foreach (GameObject go in GameObjectAll)
  //{
        //Debug.Log("GameObject name is " + go.name);
        // Debug.Log(go.name + "'s position is " + AutoKnowObjectsPosion(go));
        // will = GameObject.Find("Square");
    my = MyObjectName();
    Debug.Log("myObject name is " + my.name + " and my position is " + AutoKnowObjectsPosion(my));

    //will = go;
    if ((int)ObjectsNum < AutoKnowObjectsNum())
    {
        will = GameObjectAll[(int)ObjectsNum];
    Debug.Log("willObject name is " + will.name +" and its position is " + AutoKnowObjectsPosion(will));
   
        if (my.name != will.name)
        {
            Debug.Log("goalObject name is " + will.name + " and " + will.name + " 's position is " + AutoKnowObjectsPosion(will));
            Debug.Log("Now goal numbers is " + goalNum + "个");

            AutoMoveToObjects(my, (float)0.5, will);
            if (A2B(my, will).sqrMagnitude < 1)//到达目标物位置处
            {
                Debug.Log(my.name + " comes to " + will.name + " 's position.");

                ObjectsNum = ObjectsNum + 1;
                goalNum += 1;
                Debug.Log("Now new goal numbers is " + goalNum + "个");

            }
        }
        else
        {

            ObjectsNum = ObjectsNum + 1;

        }
    }
    else {
        Debug.Log("myObject name is " + my.name + " and my search is finished. " );

    }

    // }
}

//4-1.寻找所有物体
GameObject[] AutoKnowObjectsAll()
{
// float ObjectsNum = 0;
//寻找区域内的对象
GameObject[] bodies = FindObjectsOfType(typeof(GameObject)) as GameObject[];
return bodies;
}
//4-2 寻找所有物体数量
int AutoKnowObjectsNum()
{
// float ObjectsNum = 0;
//寻找区域内的对象
GameObject[] bodies = FindObjectsOfType(typeof(GameObject)) as GameObject[];
return bodies.Length;
}

}
机器人逐一到达各物体处，

完成巡逻任务如下图所示。

简单总结一下，本节是对圆形机器人巡检的情况做了实现。各个物体暂时均不具备刚体属性，如果各物体具备了刚体属性，同时中间如果设置障碍物的话，则不能直接走直线到达障碍物跟前，需要寻路算法。在寻路算法的基础上，可以产生最优路径解。
