Description描述

Returns a rotation that rotates z degrees around the z axis, x degrees around the x axis, and y degrees around the y axis (in that order).

返回一个旋转角度，绕z轴旋转z度，绕x轴旋转x度，绕y轴旋转y度（像这样的顺序）。

public Quaternion rotation = Quaternion.Euler(0, 30, 0);
绕Y轴旋转30°；

transform.rotation=Quaternion.RotateTowards(transform.rotation,)

4种让一个物体 移动到另一个物体的方法
direction = (cubeTra.position - shpereTra.position).normalized
单位向量化；
//第一种 +=
// if (Vector3.Distance (shpereTra.position, cubeTra.position) > 0.1f) {
// shpereTra.position += direction * speed * Time.deltaTime;
// } else {
// shpereTra.position = cubeTra.position;
// }

              //第二种 transform.translate

// if (Vector3.Distance (shpereTra.position, cubeTra.position) > 0.4f) {
// shpereTra.Translate (Vector3.right * Time.deltaTime, Space.Self);
// } else { 朝向位置 自身坐标 世界坐标为 .world
// shpereTra.position = cubeTra.position;
// }

                //第三种  每次走一半 物件接近目标

// if (Vector3.Distance (cubeTra.position, shpereTra.position) > 0.1f) {
// shpereTra.position = Vector3.Lerp (shpereTra.position, cubeTra.position, Time.deltaTime);
// } else {
// shpereTra.position =cubeTra.position;
// }

              //第四种 超某个方向移动   这个1指的是最大每帧走一米;

// shpereTra.position= Vector3.MoveTowards(shpereTra.position,cubeTra.position,0.01f);

//绕着3个点移动
public List<Transform> pointList;
int currentIndex=0;
float timer=0;

void Update () {
GoRound ();
}
void GoRound(){

transform.position =Vector3.MoveTowards( transform.position, pointList [currentIndex].position,1.0f);
} else {
timer += Time.deltaTime;
if (timer >= 2) {
currentIndex=++currentIndex%pointList.Count;
