1.1游戏对象运动的本质是什么
游戏对象运动的本质是游戏对象随着动画帧的变化而产生的游戏对象的坐标以及角度的变化。通过平移、旋转、缩放的方式改变游戏对象的transform属性。
1.2抛物线运动
（1）修改transform
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Move1 : MonoBehaviour
{public float speed = 1;void Start(){}void Update(){transform.position += Vector3.left * 1/10;//水平匀速以速度1前进,放慢十倍transform.position += Vector3.down * speed * Time.deltaTime/10;//竖直方向以加速度运动,放慢十倍speed += 10 * Time.deltaTime;//速度随重力改变}
}（2）向量Vector3，直接position加上变化向量
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Move2 : MonoBehaviour
{public float speed = 1;void Start(){}void Update(){transform.position += new Vector3(Time.deltaTime * 1,-Time.deltaTime * speed/2,0);//慢放2倍速度speed += Time.deltaTime * 10;//g=10}
}（3）translate一个向量Vector3
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Move3 : MonoBehaviour
{ void Start(){ }void Update(){ this.transform.Translate(new Vector3(Time.deltaTime * 1, - 10 / 2 * Time.deltaTime * Time.deltaTime, 0));}
}
1.3太阳系
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Random = System.Random;public class sun : MonoBehaviour
{// Use this for initializationprivate float x0;void Start(){x0= this.transform.position.x;}// Update is called once per framevoid Update(){this.transform.RotateAround(Vector3.zero, new Vector3(0, x0/10, 2-x0/8), 20 * Time.deltaTime*x0/5);this.transform.Rotate(Vector3.up * Time.deltaTime * 10000 * x0 / 5);}}
运行结果：
2、编程实践
- 游戏中的对象有：Priests,Devils,boat,one side,the other side
玩家动作 条件 开船 船在开始岸、船在结束岸、船上有人 开始岸牧师上船 船在开始岸，船有空位，开始岸有牧师 开始岸魔鬼上船 船在开始岸，船有空位，开始岸有魔鬼 结束岸牧师上船 船在结束岸，船有空位，结束岸有牧师 结束岸魔鬼上船 船在结束岸，船有空位，结束岸有魔鬼 - MVC架构：在Asserts目录下分别创建Model，Control，View文件夹
- 将游戏中对象做成预制
- 整个游戏仅 主摄像机 和 一个 Empty 对象， 其他对象由代码动态生成：
- ControlGameObjects.cs
