Unity3D 学习笔记
Unity3D 学习笔记：
- Unity版本 2019.1.0f2
- C#编辑器 Visual Studio
- 官方学习手册
- 博客干货：
- 新版Unity不再安装MonoDevelopment，可以自己设定脚本编辑器，参考：Unity3D使用VS作为脚本编辑（Unity3d与vs2015关联起来）
- 代码中控制音频文件的播放，参考：Unity代码控制音频播放
- 简单界面显示倒计时，参考：简单倒计时功能
- 其它计时方式实现，参考：多种计时器实现方式
- 点击按钮/事件触发场景的切换，参考：点击场景切换
- 多个文件共享数据/变量的实现，参考：PlayerPrefs存储与读取数据
- 场景间切换传递保存数据的方法
- RigidBody与Collision :unity 2d碰撞/ui组件碰撞
- 弹出界面，参考：unity点击按钮弹出操作提示界面
- Unity2D控制游戏对象移动与碰撞：

using System.Collections; using System.Collections.Generic; using UnityEngine; public class countdown : MonoBehaviour { public GameObject text; public int totaltime = 60; public GameObject obj1; // Use this for initialization void Start () { StartCoroutine (CountDown ()); obj1 = GameObject.Find ("Red"); obj1.AddComponent <AudioSource>(); obj1.AddComponent <AudioSource>().clip = (AudioClip)Resources.Load ("3"); obj1.GetComponent<AudioSource> ().Play(); } IEnumerator CountDown(){ while (totaltime >= 0) { text.GetComponent<GUIText>().text= totaltime.ToString (); yield return new WaitForSeconds (1); totaltime--; } } // Update is called once per frame void Update () { } }
- 实现小汽车的运动，前进后退，向左向右，旋转，加速：
using System.Collections; using System.Collections.Generic; using UnityEngine; public class car : MonoBehaviour { public Rigidbody CarRgd; public Transform enemy; //终点 public float force; //加速度 public AudioSource start; public AudioSource onaudio; public AudioSource accelerate; private bool on; private bool ac; // Use this for initialization void Start () { on = false; ac = false; } // Update is called once per frame void Update () { driving (); } void driving (){ if (Input.GetKey (KeyCode.Space)) { Vector3 dir = enemy.position - CarRgd.position; dir.y = 0; Quaternion target = Quaternion.LookRotation (dir); CarRgd.rotation=Quaternion.Lerp (CarRgd.rotation, target, Time.deltaTime); CarRgd.MoveRotation(Quaternion.Lerp (CarRgd.rotation, target, Time.deltaTime*5)); //CarRgd.MovePosition (enemy.position); if (!start.isPlaying) { start.Play (); } } //前进 if (Input.GetKey (KeyCode.UpArrow)) { CarRgd.MovePosition (CarRgd.transform.position + Vector3.forward * Time.deltaTime * 2); on = true; } else { on = false; } if (on) { start.Pause (); if (!onaudio.isPlaying) { onaudio.Play (); } } //后退 if (Input.GetKey (KeyCode.DownArrow)) { CarRgd.MovePosition (CarRgd.transform.position + Vector3.back * Time.deltaTime*2); } //左移 if (Input.GetKey (KeyCode.LeftArrow) ) { CarRgd.MovePosition (CarRgd.transform.position + Vector3.left * Time.deltaTime*2); } //右移 if (Input.GetKey (KeyCode.RightArrow) ) { CarRgd.MovePosition (CarRgd.transform.position + Vector3.right * Time.deltaTime*2); } //向右旋转 if (Input.GetKey (KeyCode.C) ) { Quaternion targetRotation = Quaternion.Euler (new Vector3(0,45,0)); CarRgd.MoveRotation (Quaternion.Lerp (CarRgd.rotation, targetRotation, Time.deltaTime*5)); } //向左旋转 if (Input.GetKey (KeyCode.Z) ) { Quaternion targetRotation = Quaternion.Euler (new Vector3(0,-45,0)); CarRgd.MoveRotation (Quaternion.Lerp (CarRgd.rotation, targetRotation, Time.deltaTime*5)); } //加速 if (Input.GetKey (KeyCode.X)) { CarRgd.MovePosition (CarRgd.transform.position + Vector3.forward * Time.deltaTime * 10); //CarRgd.AddForce(Vector3.forward*force); //CarRgd.position=CarRgd.transform.position+Vector3.forward*Time.deltaTime; //accelerate.Play(); ac = true; } else { ac = false; } if (ac) { onaudio.Pause (); if (!accelerate.isPlaying) { accelerate.Play (); } } } }
