基于unity的直升机模拟设计

上一篇文章介绍了使用unity3D进行战斗机飞行模拟的设计http://www.cnblogs.com/jqg-aliang/p/4598515.html，其实只要稍微修改一下，就变成了直升机的飞行模拟。只需要复写一下几个移动的方法就行了。

需要写的功能如下：直升机的前进，后退，左右移动，左右旋转，升高和降落

还是以数学模拟为例，我们需要几个值来控制游戏对象（直升机）的移动效果。具体参数的我就不说了，直接上代码吧。

using UnityEngine;
using System.Collections;

public class GameHelicopter : Flight
{
//这个是直升机的算法实现
//需要写的功能如下：直升机的前进，后退，左右移动，左右旋转，升降，

bool IsFBB = false, IsLRB = false;

{
if ((IsSing) || IsOnGround) return;
CurrentSpeed += speed * aircaft.Acc * Time.deltaTime;
CurrentSpeed = Mathf.Clamp(CurrentSpeed, aircaft.MinSpeed, aircaft.MaxSpeed);
if ((IsSing) || IsOnGround) return;
IsFBB = false;
Balance(Quaternion.Euler(aircaft.AxisFB * speed, body.eulerAngles.y, body.eulerAngles.z), aircaft.RoteFBSpeed * Time.deltaTime/5);
}
public override void MoveLR(float speed)
{
//左右移动
if ((IsSing) || IsOnGround) return;
//IsLRB = false;

currentMLRSpeed += speed * Time.deltaTime * aircaft.Acc;

currentMLRSpeed = Mathf.Clamp(currentMLRSpeed, -aircaft.MoveLRSpeed, aircaft.MoveLRSpeed);
/*Vector3 vector = body.right;
vector.y = 0;

//Move(speed * vector * aircaft.MoveLRSpeed * Time.deltaTime);*/

Balance(Quaternion.Euler(body.eulerAngles.x, body.eulerAngles.y, -aircaft.AxisFB * speed), aircaft.RoteLRSpeed * Time.deltaTime * 3);
//print("MoveLR" + speed);

关于测试代码也很简单，输入检测一下，然后调用直升机的控制代码就行了，这里就不提供了。
