一、沿固定路线走（创建Nav2文本）
//1.固定路线走，都给小球设置标签Path01
//2.把方块Player拖成预制体,写文本CreateEnemeies给了空文件夹，参数count不用填，，可以改程序中的count< ,Nav2给了预制
体，可把小球的Mesh的√去掉，就不显示了
//3.可写创造一波怪物按固定路线,暂时只能创造一波怪物，等用协程写
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------
开始：Nav2文本
1.. publicGameObject[] pathPoints;
//
public GameObject player; //去掉player，就不特指某个对象了,如果只是让一个固定对象沿着固定路线走， 就不用克隆的
那个脚本了，而且也要加上Player，文本给了Player.
//记录下一个路点
intnextPathPointIndex = 1;
1.void Start () {
pathPoints = GameObject.FindGameObjectsWithTag("Path01");
// Array.Reverse(pathPoints);翻转排序，最简单的方法，下面的排序高大上些。
Array.Sort(pathPoints, (x, y) => { returnx.gameObject.name.CompareTo(y.gameObject.name); }); //排序，得到所有路点
transform.position = pathPoints[0].transform.position;
transform.forward =pathPoints[nextPathPointIndex].transform.position - transform.position;
}
2.void Update () {
if(Vector3.Distance(pathPoints[nextPathPointIndex].transform.position,
transform.position)<0.1f)
{
if(nextPathPointIndex !=pathPoints.Length-1)
{
nextPathPointIndex++;
}
if(Vector3.Distance(pathPoints[pathPoints.Length- 1].transform.position, transform.position)<0.1f)
{
transform.position =pathPoints[pathPoints.Length - 1].transform.position;
return;
}
transform.forward =pathPoints[nextPathPointIndex].transform.position - transform.position;
}
transform.Translate(Vector3.forward * 5 * Time.deltaTime, Space.Self);//以自己的轴走动
}
2. CreateEnemeies文本
//克隆产生敌人,生成一波敌人的数量
----------------------------------------------------------------------------------------------------------------------------------------
float timer = 0;
float timer2 = 0;
//产生敌人的速率
publicfloat rate;
//敌人的预制体
publicGameObject enemeyPrefab;
//每一波的时间
publicfloat timesofEachWave = 30;
//每一波的已经产生的数量
publicint count;
1.void Update () {
timer2 += Time.deltaTime;
if (timer2 < timesofEachWave && count != 10)
{
timer += Time.deltaTime;
if (timer > rate)
{
Instantiate(enemeyPrefab, Vector3.zero, Quaternion.identity);
count++;
timer -= rate;
}
}
}
