PS:本系列笔记将会记录我此次在北京学习Unity开发的总体过程,方便后期写总结,笔记为日更。
笔记内容均为 自己理解,不保证每个都对。

Demo地址:

Part 1 Transform组件:

常用属性:

属性名

作用

position

世界坐标系中的坐标

localPostion

相对于父类的坐标

eulerAngles

相对于世界的欧拉角

localEulerAngles

相对于父类的欧拉角

parent

返回父类

例如:

Vector3 temp = new Vector3(1, 1, 1);
 AI.transform.position = tempVector;         //设置生成AI的坐标
 
 bullet.transform.SetParent(transform, false);		//设置父类为当前游戏物体

Part 2 Input:

输入主要包括:键盘 ,鼠标 , 手指 , 摇杆,手柄。

键盘输入: 括号内是 KeyCode.按键

属性

操作

Input.GetKeyDown()

按键按下,触发一次

Input.GetKeyUp()

按键松开,触发一次

Input.GetKey()

按键按下, 一直触发

鼠标输入: 括号内是 0鼠标左键, 1鼠标右键, 2鼠标中键

属性

操作

Input.GetMouseButtonDown()

按键按下,触发一次

Input.GetMouseButtonUp()

按键松开,触发一次

Input.GetMouseButton()

按键按下, 一直触发

轴输入: Mouse X (水平轴) Mouse Y (垂直轴) Mouse ScrollWheel (鼠标中键滚动)

属性

操作

Input.GetAxis

Input.GetAxisRaw)

自定义设置属性:Edit->Project Setting->input

unity 动态获取BUTTON_游戏开发_02

Part 3 获得物体:

1,GameObject.Find(“Player”) 通过名字

GameObject target = GameObject.Find("TankPlayer");      //寻找玩家

2,GameObject.FindGameObjectWithTag(“Player”) 通过标签

GameObject TankAiS = GameObject.FindGameObjectWithTag("AI");     //用GameObejct数组找到场景内所有 Tag 为AI的物体

3,GameObject.FindGameObjectsWithTag(“Player”) 通过标签 找多个物体

GameObject[] TankAiS = GameObject.FindGameObjectsWithTag("AI");     //用GameObejct数组找到场景内所有 Tag 为AI的物体

4,Public
脚本内声明,脚本外拖入

实例化物体过程:
1,物体放入 Resources 中
2,Object tmpObj= Resources.Load(“预制体名”); 加载到内存中
3,GameObject tmpGameObj= GameObject.Instantiate(tmpObj) as GameObject 实例化到
场景中。

Part 4 坦克大战DEMO:

            tempVector.z += Random.Range(4, 20);        //随机生成Y轴

            AI.transform.position = tempVector;         //设置生成AI的坐标
            timeCount = 0;          //计时器归零
