C#或unity中实现正弦函数
本类用于第一，需要绘制一条正弦曲线的朋友；第二，需要根据正弦曲线控制物体运动的朋友；里面都有注释，代码如下：
unity中使用的代码：
public class Curvy_Sin { /// <summary> /// 周期 /// </summary> private float lifeTime = 2; /// <summary> /// 波峰 /// </summary> private float MaxPos = 0; /// <summary> /// 波谷 /// </summary> private float MinPos = 0; /// <summary> /// 计算时使用的周期，避免周期为小于零的情况 /// </summary> private float ZQ { get { if (lifeTime <= 0) { return 2; } else { return lifeTime; } } } /// <summary> /// 构造一个正弦曲线 /// </summary> /// <param name="zhouqi"></param> /// <param name="minp"></param> /// <param name="maxp"></param> public Curvy_Sin(float zhouqi, float minp, float maxp) { this.lifeTime = zhouqi; this.MinPos = minp; this.MaxPos = maxp; } /// <summary> /// 根据X轴获取对应Y轴的值 /// </summary> /// <param name="x"></param> /// <returns></returns> public float GetZhengXianValue(float x) { float innner = (2 * (float)Mathf.PI) / ZQ; float ya = (float)Mathf.Sin(innner * x); float maall = (MaxPos - MinPos) * 0.5f; float middle = maall + MinPos; return (middle + maall * ya); } /// <summary> /// 修改正弦参数 /// </summary> /// <param name="zhouqi"></param> /// <param name="minp"></param> /// <param name="maxp"></param> public void SetCurvyZhengXian(float zhouqi, float minp, float maxp) { this.lifeTime = zhouqi; this.MinPos = minp; this.MaxPos = maxp; } }
C#中winform或WPF
