几何中我们要画一个圆，因为圆的标准表达式是 圆心为（a,b）,半径为r。那么我们只要知道圆心和半径就可以了。 我们只要知道圆心，半径，和旋转弧度就可以了。 在Unity中创建测试工程，添加代码Circles using UnityEngine; using System.Collections; public class circle : MonoBehaviour { public GameObject circleModel; //旋转改变的角度 public int

using System; using System.Collections; using System.Collections.Generic; using UnityEngine; public class Matrix : MonoBehaviour { // Update is called once per frame void Update() { //Vector2 ve = RectTransformUtility.WorldToScreenPo
