unity3D网络游戏实战之坦克单元

      之前学的是建模，用C#编写游戏刚入门，也有很多小错误，和最开始写c是一样的，很多看着书都能敲错，所以把小错误记

下来。

1.对坦克进行上下左右控制。应该写成Tank结果把名字小写了，导致很长时间没看出来

void Start()
    {
        target = GameObject.Find("Tank");
    }

2.在写完程序后一定要先运行，先在VS中运行了，才能在unity中实现相应操作

3.控制坦克的移动这段程序我们要把C#托在Tank上才能实现

控制炮管、炮塔：

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class Tank : MonoBehaviour
{
    public Transform turret;
    public Transform gun;
    private float turretRotSpeed = 0.5f;
    private float turretRotTarget = 0;
    private float maxRoll = 10f;
    private float minRoll = -4f;
    private float turretRollTarget = 0;
    void Start()
    {
        turret = transform.FindChild("turret");
        gun = turret.FindChild("gun");
    }
    private void Update()
    {
        float steer = 20;
        float x = Input.GetAxis("Horizontal");
        transform.Rotate(0, x * steer * Time.deltaTime, 0);
        float speed = 3f;
        float y = Input.GetAxis("Vertical");
        Vector3 s = y * transform.forward * speed * Time.deltaTime;
        transform.transform.position += s;
        TurretRotation();
        turretRotTarget = Camera.main.transform.eulerAngles.y;
        turretRollTarget = Camera.main.transform.eulerAngles.x;
        TurretRoll();


    }
    //炮塔旋转
    public void TurretRotation()
    {
        if (Camera.main == null)
            return;
        if (turret == null)
            return;

        //归一化角度
        float angle = turret.eulerAngles.y - turretRotTarget;
        if (angle < 0) angle += 360;

        if (angle > turretRotSpeed && angle < 180)
            turret.Rotate(0f, -turretRotSpeed, 0f);
        else if (angle > 180 && angle < 360 - turretRotSpeed)
            turret.Rotate(0f, turretRotSpeed, 0f);
    }
    public void TurretRoll()
    {
        if (Camera.main == null)
            return;
        if (turret == null)
            return;
        //获取角度
        Vector3 worldEuler = gun.eulerAngles;
        Vector3 localEuler = gun.localEulerAngles;
        //世界坐标系角度计算
        worldEuler.x = turretRollTarget;
        gun.eulerAngles = worldEuler;
        //本地坐标系角度限制
        Vector3 euler = gun.localEulerAngles;
        if (euler.x > 180)
            euler.x -= 360;

        if (euler.x > maxRoll)
            euler.x = maxRoll;
        if (euler.x < minRoll)
            euler.x = minRoll;
        gun.localEulerAngles = new Vector3(euler.x, localEuler.y, localEuler.z);
    }
}

在进行加车轮的过程中，看了原代码把控制坦克行走的部分删除了，但结果又要求行走，由于一时没想到就把代码全删了，后来又从新写了一遍，之前有点没理解。说之前的两种方法可以删除了，不知到说的哪俩种，导致都删了。

红色部分不能删

最后运行游戏轮子和履带不转动，不知道什么原因。。。
