不对之处，敬请谅解。
1.圆内接正七边形半径
public static float r = 10;
2.存储七个顶点的值
Vector3[] ar = new Vector3[7];
3.圆心角
static float circleAngle = 360 / 7*Mathf.PI/180;
static float ca3 =2 * circleAngle-90*Mathf.PI/180;//第三个顶点的夹角
图示：
4.计算顶点坐标
static float a2y =Mathf.Cos(circleAngle) * r;
static float a2x =
Mathf.Sin(circleAngle) * r;
static float a3x = Mathf.Cos(ca3) * r;
static float a3y =
Mathf.Sin(ca3) * r;
static float a4x = Mathf.Sin(circleAngle / 2) * r;
static float
a4y = Mathf.Cos(circleAngle / 2) * r;
5.对顶点赋值
Vector3 a1 = new Vector3(0, r, 0);
Vector3 a2 = new Vector3(a2x, a2y,
0);
Vector3 a3 = new Vector3(a3x, -a3y, 0);
Vector3 a4 = new
Vector3(a4x, -a4y, 0);
Vector3 a5 = new Vector3(-a4x, -a4y, 0);
Vector3 a6 = new Vector3(-a3x, -a3y, 0);
Vector3 a7 = new Vector3(-a2x,
a2y, 0);
7.初始化顶点
void Start()
{
ar[0] = a1;
ar[1] = a2;
ar[2] = a3;
ar[3] = a4;
ar[4] = a5;
ar[5] = a6;
ar[6] =
a7;
}
8.更新物体位置
void Update()
{
if (i<7)//当循环一圈后置为零
{
this.transform.Translate(ar[i].x,
ar[i].y, 0);
}
else
{
i = 0;
}
}
